Java Tutorial 2: Introduction to Java and Java Environment Setup Video Lecture | Selenium Test Automation:Tutorial for Beginners (English) - Software Testing

say selenium classics introduction to
Java see in this chapter we are going to
discuss introducing Java programming
language Java environment set up next
Java program structure see introducing
java programming language next Java
environment setup environment set up
next Java program structure Java program
structure okay say first I am taking
Java introducing Java C
reintroducing java programming language
say java programming language was
developed at Sun Microsystems in 1991
but the first publicly available version
of java java 1.0 released in 1995 20
years completed next now it is subset of
oracle corporation c in 2010 occurred by
oracle corporation c he introducing java
programming language java programming
language java programming language was
developed was developed at Sun
Microsystems Sun micro systems in 1991
the first the first publicly available
publicly available
version of Java that is Java 1.0
released in 1995 released in 1995 next
now it is subsidiary of Oracle
Corporation now it is subsidiary of
Oracle next Java is an object-oriented
programming language in Java
everything is object except primitive
datatypes Java can be easily extended
since it is based on the object model we
can we can easily reuse methods and
fields fields means variables next Java
is object oriented programming language
what about seek or not yes sir I have a
quick question sir what is I do not know
much about the programming so what is
different between object use and method
sir I do not know sir say in future
classes you can get more clarity okay
chef sir thank you sir tell me good nod
yes sir ah ah T what about C programming
language Java is object oriented
programming language what about C
language okay you don't know programming
language na naled rishabh nella Dre can
you tell me yes see the structure with
structured programming language not
basic structure is not base structured
programming language Java is object
oriented programming language
VB script is object-based
scripting language object-oriented
object abrasive okay
next Java is platform independent it can
be compiled as well as he interpreted
what is interpreting I will explain Java
is simple easy to learn and easy to
implement next a developer point of view
developers point of view Java is
securable using Java we can develop
virus free and tamper free systems it is
not for testers it is for dollar purse
okay
anyhow Java primary purpose is
development only half Dalek meant
application development not test
automation test automation is secondary
use not primary use okay say Java
observe guna ague nod you must know some
basics about controller programming in
our Suri requisites also I mentioned
computer programming fundamentals too
much' says programming fundamentals go
through that one second Java Java is an
object-oriented object-oriented
programming language object-oriented
programming language in Java
everything is object everything is
object except primitive datatypes
next Java can be easily
extended since it is based on the object
model Java can be easily extended since
it is based on object model C next point
Java is a platform independent language
it can be compiled and interpreted Java
is a platform independent platform
independent language it can be compiled
it can be compiled and he interpreted
say you know compile compile Asian say
converting high-level language into
mission level language that is
compilation it can be compiled and
interpreted say it is flat form
independent language now you can you can
use Java on Windows platform next UNIX
platform Macintosh platform any platform
suppose write Java program on Windows
compile and run see three steps in
computer programming Oh writing program
compiling the program and executing the
program write program on Windows compile
the program
and Rhonda program next another scenario
right program on unix compile the
program and run the program next another
scenario write program on macintosh
compile the program and run next
interpreted naam suppose write program
on Windows compile the program then it
will create class file you copy that
class file execute that file on Windows
and UNIX you no need to write the
program again and compile I compile it I
write one program on Windows and compile
after compilation you can get class file
you copy that class file execute on
other environments other operating
environments Unix Linux Macintosh etc
this is interpreting getting this point
nil Adri yes a writing program on one
environment one operating environment
and compile after compilation copy that
class file you execute that class file
in another operating environments it can
execute or can on guru nod it sir got
itself sir I have one question what is C
sir it is this is hoops right
object-oriented but C is what is a
structured programming language but the
structured programming thank next Java
is simple easy to learn and implement C
Java is simple easy to long
and implement next one more point just a
minute
this is developers point of view Java is
securable Java is securable using Java
using Java we can we means developers we
can develop virus free and tamper free
systems system means application in this
scenario say these are the important
points ah Smith are you following
Smitha it's any confusion Sangeeta so
far good ok cool Sanji debacle re
following yes Alfred
ok cool safe next one general topic
observed not general topic is a usage of
Java usage of Java we are going to use
Java for test automation but test
automation is not the primary purpose of
Java Java was not dollar profit
estimation Java developer for software
development not for testing ok secondary
purpose test automation what are the
primary uses of Java say
observe using Java we can develop we
means developers developing desktop
applications developing otherwise to
develop desktop applications can I give
an example
Sanji da can you give an example for
desktop application calculated paadam
calculator calculator okay any other
what about notepad notepad also desktop
application ah yes
not browser-based okay example Acrobat
Reader Acrobat Reader next to develop
web applications you say Java can be
used for developing websites to develop
web applications so many examples next
to develop enterprise applications to
develop business applications enterprise
applications enterprise applications
for example banking applications
insurance applications etc banking
insurance insurance applications etc
next to develop mobile applications
mobile software to develop mobile
applications next to develop embedded
systems soon L what is the embedded
system to develop the head system
embedded systems gulping cups
ah yes L mean L embedded systems
inserting software program into devices
electronic devices are mechanical
devices for example lift operating
program telephone Cayenne box etc C
inserting software components into
devices embedded systems chip
programming etc next to develop smart
cards next to develop game software
games
Xsara what a smart cut sir
smart cards ATM card software credit
card software etc next our purposes
observe 3d observe Smitha what is our
purpose to develop desktop applications
or web applications or enterprise
applications know all these our
development next our purposes test
automation test automation actually the
secondary purpose
tell me predict usage of Java general
topic usage of Java it is used for the
developing desktop applications ah
for example a program a production just
to list out ah developing web
applications ah develop enterprise
applications ah developing mobile
applications developing federal systems
embedded systems ah yes my cards and get
soft face okay etc next hour our usage
is estimation estimation actually if not
the memory primary usage secondary
secondary you see Oh
Okin an ela Dre 2 topics we discuss
there one is introducing Java under the
introducing Java usage of Java nella 3
any confusion no sir
oh can you welcome Java syntax Java
in tax say I will I will introduce Java
syntax in brief manner in Java program
structure chapter we will discuss with
examples now only theoretical approach
first one Java is a case since two
language Java is a case sensitive case
sensitive
language for example VB script VB script
used in U of T test automation that is
also secondary purpose VB script not
case-sensitive no difference between
upper case and lower case values
goodness did you understand this concept
Java is a case sensitive language what
is the meaning cases to unity node is it
when you look at its cases to me is like
an upper case and lower case land it can
have n vertices there in between upper
case and lower case values okay I think
so
it's different okay difference is there
in between upper case and lower case
values alphabets for example capital ABC
is different small ABC is different but
in VA script capital ABC small ABC both
are same okay say case sensitive where
say Java is a case sensitive language in
case of variable names operator names
conditional statements loop statements
all Java keywords all Java keywords are
essence too for example messages
messages not sensitive comments not
sensitive but all Java
woods reservoirs are sensitive and some
user-defined keywords also sensitive
yours are definer keywords see sometimes
we define keywords for example
user-defined method you can use your own
name but user definer keywords also
sensitive soon L following this concept
taste sensitive language yes sir ok next
first letter of fake first letter of
class name say in Java we create classes
in the class file only we write program
the class file we write Java program
first letter of class name should be in
uppercase second letter on words you can
use small letters or numbers first
letter should be uppercase next method
names should start with lowercase letter
next I am introducing important Java
syntax rules in Java program structure
chapter I will give you examples next
Java program file names should exactly
match with class name next Java program
execution starts from main method which
is mandatory in every Java program next
some formalities every statement our
step should end with semicolon symbol
but in VB script no such type of
formalities you can write plain
statements or steps but in Java every
statement should end with semicolon in C
language also said
in parallel script also said gnashed
codeblocks
example condition block if condition
block next loop blocks method blocks etc
code blocks enclosed with curly braces
observed first one Java is a case
sensitive language next first letter
first letter of class first letter of
class name class name should be in
uppercase uppercase next Java method
names method names pretty method names
should start should start with little
lowercase letter lowercase since the
data question can a ah the data is case
sensitive forum data type is case
sensitive data type yeah data type means
what is the keyword or value C in data
type two things are Dana anyhow it is
not time to discuss the concept just a
minute suppose int a equal to ten number
leave it the number suppose cha
be equal to capital yay here two things
one is char CH AR his datatype this is
Java keyword what is this big bees
variable name
what is this capital a capital e is
value now which one you are asking can't
be this B yes yes B also sends to you
can in our case our lowercase uppercase
or lowercase but sensitive suppose if we
use B ba just a minute suppose
cause I want to print this one print
Ellen off capital B is that correct
syntax are in correct syntax in current
incorrect now since tuna yes since two
but you can use suppose char B also that
time that is car this is correct syntax
but you can't use char this is incorrect
this is Java keyword Java keywords in
lowercase only but variable names you
can use uppercase or lowercase if we use
uppercase use uppercase only if you use
lowercase use lowercase only in other
statements values also same capital a it
will display it will use capital here
suppose if we use smaller it will you
small e getting this pointed in a
confusion no said thinking okay say
method name should start with lowercase
letter next Java program file name
should exactly match with class name
Java program file name program file name
should exactly match with class name
next Java program execution starts from
main method Java program execution
starts from main method if you don't
right main method program won't be
executed say which is mandatory it is
mandatory mandatory in every Java
program every Java program next every
statement our step should end with
semicolon every statement are step
synonyms should I end with semicolon
semicolon symbol next a code blocks code
blocks blocks not normal statements
blocks give some examples for blocks
code blocks
Sanji de indirectly I mentioned give
some examples for code blocks
conditional statements yes conditional
block conditional statements loop
statements method method declaration etc
ha are you following yes sir CA where
you disconnected and connected several
times what is the problem
yes I had system issue sir
no it's getting okay now now : yes sir
okay cool
see code blocks he enclosed with and
closed with what is the symbol flower
brackets curly brace corrected curly
braces okay see these are the important
syntax rules gharana do not tell me what
are the important Java syntax rules so
Java syntax is Lucknow it is course it's
K since - sir ah and the first letter
should always begin with the uppercase
letter sir ah and method M should start
with lowercase first telegraph class
name
okay next matter names method names
should start with lowercase sir okay
then the Java file name do should be
same as program program file name should
be same as the class name sir and
compartment one Java program execution
starts from main method seven method
which is mandatory in every every
programs every Java program Naxos and
every statement should end with
semicolon next we saw blocks enclosed
with Club racism curly braces okay next
next topic important one Java
environment setup Java environment setup
say first steps steps first step
download Java software download Java
software JDK Java development kit while
JDK in this JDK you can find javac Java
C Java command using the Java command
you can compile Java programs from
command prompt also command prompt ok
download Java software and install
install this is first step ok
next set environment variable path set
environment variable path a variable
name also path path variable
Oh Chanel have any idea why we need to
set an environment variable path yeah
generally whenever we install Java in
any C Drive or somewhere moon offense
you should understand where exactly it
is located in the in the control panel
we set the environment it will say not a
troll' panel okay say in order to
execute Java software from any directory
in the computer we set environment
variable path using if you set
environment variable path then you can
use Java software from any directory in
C Drive okay now and one more thing
use the Eclipse IDE you no need to set
this environment variable path if you
want to use command prompt to set this
environment variable path anyhow I will
show that one we will discuss how to
write and execute java programs using
command prompt as well as Eclipse IDE
but in our training program not only
training program in real time also we
use IDE only not command prompt Eclipse
IDE see first we discuss how to write
and execute Java programs later we added
webdriver Java bindings to Java project
in Eclipse and we can execute webdriver
code also at end we install test ng RJ
unit framework also in Eclipse so in
real time we use ID but I will show how
to write and execute programs using
command prompt that is basic concept
okay next
download Eclipse IDE and extract no need
to install download Eclipse Eclipse IDE
integrated development environment and
extract then you can write and execute
programs using Java programs using
Eclipse IDE ok just a minute you observe
how to download pretty observe type Java
download in Google search engine Java
download say you can download Java
software from either java.com our
oracle.com suppose oracle.com observe
gunas here Java platform JDK is there
now it says if you click this download
image link next location accept the
agreement
see it is also free software open source
here select executable file based on you
are operating environment see here linux
solaris windows available mac Xsara see
suppose - windows x86 32-bit operating
system suppose your sees a windows
64-bit you download this loss the exe
file suppose - windows x86 operating
system see here click this executable
file link then save the file on tell on
hard disk
after save you can get this type of file
just a minute
footnote see here JDK Windows this
executable file click this one here it
will provide the guidance install this
one simple installation it will provide
installation guidance okay follow that
guidance and install after installation
just a minute
open C Drive Program Files here you will
see sir ice-cream got that blacked out
this is furniture problem from your side
good not his wherever rising tokens for
everything what about you nail Adri can
you my desktop and here he has a guru
knuckles I also have the same thing they
connect and connect again now right now
is everything fine of the SATA file you
click it was black black stream this way
what about using in just a minute so
nearly yeah the blank screen was
appeared for a dog scale ok göransson
would not see after installation you can
get Java fold up c program files java
can you be this java folder Sridevi
what about you nella 3 can you view this
Java folder yes goo not now you are
getting properly are still desktop
sharing problem for a minute sir when
you are trying to extract the file I
think so that's the only time sir okay
that's so now now it is ok yes sir
amiable Caesar no problems okay cool say
when
you face any problem ask me okay this
time not problem not from your side okay
say once again guide me Sridevi how to
download and install Java software JDK
software guide me gave me the steps I
said first we need to download Java
software from Oracle or Java dot some
just a minute
suppose a gave me grade missteps suppose
Java download here showing first aside
Java calm next site of oracle.com okay I
am selecting Baraka calm based on our
system configuration if account next
select this one Java platform JDK image
link click this link next first we
access the license agreement next based
on our computer operating environment
select the executable file and download
to computer hard disk ok after download
you can get this file this one JDK
something lost file
next click this file follow the
installation guidance and install after
installation how to confirm nail Adri
yes sir we have to go inside right anger
we drive who broke acid web for over
half minds in this program files you can
find Java folder na yes sir Java folder
is there ok this is about download and
install JDK software ok
next set
environment variable path set
environment variable path C navigation
navigation say faster first take JDK bin
JDK bin directory path first take JDK
bin directory path how observe observe
Sanji de click say drive program files
next Java JDK bin you take this path JDK
bin directory path from address bar next
select my computer and right click
properties next advanced system settings
next environment variables next here two
types of environment variables first
half user variables second half system
variables select system variables here
select a path variable suppose if you
don't find path variable you can create
new variable suppose path variable
already there added here in this value
variable value field provide that bin
directory path click ok again click ok
ok close my computer ok just guide me
gay San Jesus tell me the steps select
my computer
yes and then right click select my
computer and right click advise Lake
just a minute
next add visiting advanced system
settings next then environmental
variable the environmental variable just
terminate right click properties
yes then advanced and system settings
just a minute before advanced system
settings properties properties
properties next environment variables ah
next you know then system defined from
system defined variable kinetic variable
select the path variable in system
variables yes and just edit selected
path variable variable from system
system variables suppose if path
variable
not available then you can create new
variable Nations added here did AA
gnashed ready and then first them when
we copy the okay already
I mentioned that prerequisite first it
take it if index report can't paste bin
directory
Java bin directory Java bin directory
path in variable value field next okay
okay okay observe okay okay close oaken
on Smitha set environment variable path
just a guide make quick how to set a
path variable environment variable just
to guide me quick okay
first select of my computer select my
get a right click on the computer right
click and properties advanced system
settings
not able to use the screen yeah I can
view the screen environment variables
next shall I stay with variability
systems where a system variables click
Edit play a paste variable JDK bin
directory path and variable value field
click OK okay okay
close ok now yes okay not gonna are you
following this one now two steps here I
have one equations are when you go to
the where you get let me use it 32-bit
or 64-bit how will I know my system
information sir see that is not relevant
or training program no sir I do not
watch I don't know which one $2 if I
have to download see you need to observe
your system 32-bit are just a minute ok
how will I know that's all I do know is
not relevant
don't ask relevant questions say also
here my computer there nah ok 40
properties here it is showing system
type what a system type 32-bit operating
operating system say this question is
not relevant she says say 32-bit of 62
bit that you have to you have to observe
that one ok sure gotta say thank you say
how to install on how to use only we
will discuss ok short circuits say
32-bit operating system see observe my
computer and right-click properties here
system type 32-bit operating system
suppose ever sees Macintosh or Linux
that is different Navigation
say okay two steps over Chanel download
and installing this one Java JDK
software next set environment variable
next download Eclipse IDE and extract
download eclipse ID this is also open
source say Eclipse ID say select this
one Eclipse Jie Mars package Java EE
here windows 32-bit based on your
operating system select Windows Touch
2-bit 64-bit Mac we X Linux 32 lion x64
etc see this layer this Eclipse site is
very slow free site na server is very
slow just a minute
here download download say we have
different flavors of Eclipse see save
the file
observe
Sandi de you save the file to hard disk
yes okay now yes sir
otherwise see in our website also we
have download link you can directly
click that one initiative this lengthy
navigation observe here selenium
tutorials here selenium downloads Java
software link next Eclipse IDE link
click this Eclipse IDE link observed nod
yes sir thanks her welcome it is slow
side eclipse in this terminate Eclipse
IDE link
not responding properly okay you can use
this link Eclipse IDE link otherwise you
can directly download from Eclipse dot
huazi website after downloading you can
get this folder zip version
observe Smitha eclipse see different
flavor we have different flavors of
Eclipse Eclipse Mars Luna you try to
download Mars you can download other
flavors also no issue after downloading
this folder next extract extract just a
minute I already extracted just a minute
where it is after downloading eclipse
extract after extraction you can get
this Eclipse folder no need to install
just click the folder here you can find
Eclipse file absorb nella 3 you can find
Eclipse file now yes sir click the take
eclipse file run it will launch Eclipse
IDE integrated development environment
launched ok just to close this one ah
Smitha guide me download and extract
Eclipse IDE just guide me suppose
cannot clips 2x clips download I Eclipse
IDE here Eclipse dot war the site is
there now you select eclipse downloads
see it is very slow subside just a
minute see it is free sale freeware
that's why is taking more time
our next here religious are there Nam
are Sunni on lunar different flavors you
Selma us suppose you select Mars
packages and configuration Eclipse IDE
for ah here selected filters like
depends are never and depends on your
operating environment suppose windows
32-bit already clickable but slow site
is very slow just a minute
but it is taking our next Eastham it is
showing just a minute
I extract the folder suppose filter and
filter the order no need to know need to
install yeah
data folder after a care action you can
get this folder here you open the
Eclipse folder then you can find Eclipse
file click this file one next to ok
Eclipse IDE launch it now yes ok I will
show Eclipse IDE later first basic using
command prompt Neela dream try to follow
hostages I will show write write and
execute write and execute a Java program
using command prompt command prompt
next save write and execute a Java
program using you're not using Eclipse
IDE is a Clips Aidid
shanell you disconnect and connect again
can you hear me Sanji de yes sir
clear say Chanel I am NOT in note to
disconnect and connect again I am NOT in
mute melody can you hear me yes sir try
and fear cool cool say these to forget
about first one we follow second one
only in our test automation in real time
also see just the basic knock first I
will explain these two methods Eclipse
IDE then I have question tell me
so just now you said rater the Eclipse
IDE has so many flavors right the Mars
and Leon barcelona kappa yeah so is
there is a very big difference in those
are no small herbs and some files extra
ok but our but we can write in java
programs in any flavor no issue
ok ok thinking down ok say Sunil Sunil
you disconnect and connect again
say first right say in computer
programming in computer programming we
have three steps say in computer
programming we have three steps first
one is write program who write program
soon L yeah anybody here not say ok
whenever you face this type of problem
you just disconnect and connect again
suppose all of this is the same problem
then I I will find the solution say
bribes program next compile compile the
program say writing program in any
editor editor required suppose Eclipse
IDE provides the editor and other tools
compilation auto compilation etc next
suppose if you want to use command
prompt you can take notepad as editor
say for writing computer programs editor
required for example notepad for 8
program in any editor next compile the
program what is compilation say
converting the high level
language into converting high-level
language into machine level language say
you take any computer program we use
high level language English English is
high level language for computers not
for human beings English is high level
language for Computers Computers no only
binary language zeros and ones but in
our computer programs we use high level
language English if for do all these are
English words getting this points Angie
de yes sir a system does not know about
English language system knows only
binary language in company computer
compiler converts high-level language
into machine level language that is
compilation yes next third step execute
or run the program run or execute the
program
see these are the three important steps
in computer programming write compile
run okay next
our first step override program first
step
oh right
program don't concentrate on this syntax
we will discuss syntax tomorrow in
program structure Java program structure
chapter now just concentrate on how to
create and execute Java creating and
executing a Java program don't
concentrate on the syntax okay see I am
writing one small program public class
class name sample open curly braces
close curly braces C class declaration
next every Java program execution starts
from main method right main method
public static void
what is this public what is static what
is wide I will explain tomorrow void
main open paranthesis string open square
brackets orgs close parenthese open
curly braces close curly braces this is
basic structure here you can write after
main method you can write your
statements suppose I am writing single
statement system dot out dot println of
string type data message hello' java
world
semicolon this is normal statement this
is one simple program okay
provide this program in editor create a
launch notepad notepad just tell
do not wheat I put that steps now just
tell me class declaration faster suppose
public public class sample suppose
public class class name sample are
something awesome only racism should
start with captain let us craft a letter
open curly braces following closed curly
braces it's a next then we prepare the
trust then when Marisa we methods a
public attic wide I like England is
keyboard tomorrow public static void
main
next open parentheses string square
brackets square square brackets orbit
close close parenthesis and open curly
braces closing of the braces with next
right or right one normal statement
suppose system s capital system this is
class built-in class system dot out dot
println print Ellen display statement
for example any meaningful message hello
Volvo Java world next this is normal
statement na every job or statement
should end with a semicolon next save as
Java file save as Java file we have to
use same class a class name and the
program file name should be same nah
it's a sample save as salesman sample
extension is Java sample dot
Java suppose I am saving on desktop save
close this was say observe the sample
java how to edit this file select the
file and right click edit' after edit
just to save the file okay
sample dot java first step over next
just a minute
step two just a minute
step one next step to step to compile
the program come file the program
compile the program here observe first
change to first launch launch command
prompt command prompt next change to
java program file directory suppose java
program file are available on desktop
change directory change to java program
file directory directory next are type
just a minute first launch command
prompt next change to java program file
directory next type small letters
jaywalk java c javac means Java compiler
next program file name program file name
what is the program file name
sample dot Java whoa
here after compilation it creates Java
class file it creates Java class file
this is second step next step three or
one run the program are execute the
program run or execute okay how to run
say type Java and class file name
extension not required see in command
prompt type Java it is command next
class file name here class file name is
sample extension not required then it
displays the output it displays the
output on the console system console
computer console
suppose if we use Eclipse ID ID console
okay just guide me
Sanji de first step for writing java
program next second step compile the
program say i
a Java program on desktop sample dot
java next i want to compile and run
compile and run ah we will we will go to
the CMD uh CMD okay and set the file
path set file bottle is distal of our
change directory that concept is change
directory for cds desktop why desktop
our program file available on desktop
next and then i did you Java Java Java
the Java C Java Java compiler space I'll
name dot dot java enter era sample dot
Java what is the problem it has actual
syntax error in our program just a
minute
edit println syntax error see it doesn't
provide syntax guidance why it is
notepad editor if it is Eclipse IDE you
can get guidance syntax guidance and
errors etc ok println save now again
compiled Java
see space s capital sample dot Java Java
small enter after comparison you can get
class file just observe that one
dar observe gunas in this directory
can I get Java class file
yes simple doctrine sauce sample dot
class is there not it's a racer okay
just a minute here eggsy continuous
Angela Romulan egg
run run only the class name ah what is
the command for executing Java program
or compilation Java C Java
yen for resident just a Java Java Java
the class name yes custom class file
name and Inter samples enter observe it
is providing output on the console not
yes sir
hallo Java or Alden isn't it yes sir I
just a minute edit the program suppose
select the program file and right click
added suppose I am writing one more
statement one more display statement
hallo selenium hallo selenium now to
display statements save save run Java
sample
what happens Angela it is showing single
output only but we have two outputs to
stay in it we need to compel again
compiler it say after editing the
program compile again otherwise you
cannot get that rocket put updated
output again compile Java see next
program file name sample data sample dot
Java
okay next Java sample now we can get two
outputs na hello Java world and hallo
selenium econo econo Sunil
yes sir I got it okay writing program
compiling gunas any confusion writing
compiling and run using command prompt
search a little bit sir can you put a
space between two line forum any space
between two line who is asking today as
Sanjana between two lines where yeah
yeah over there there is no space in
between two line oh we can issue
discontinuous display ah
can we put a space in between two lines
space okay that is different concept you
don't concentrate on putting spaces are
on something that that is a different
concept you at this point of time you
concentrate on writing compiling and run
the program
okay now yes sir yes we can use line
also that is different one next same
same second one right program in Eclipse
okay all right same using Eclipse IDE
Eclipse IDE
now brief interaction about Eclipse IDE
observable Adri Eclipse IDE integrated
development environment
Smitha have any idea what is Eclipse IDE
well Eclipse IDE is used to run the
program ran on writing writing and run
program okay integrated development
environment say Eclipse IDE is a
platform to create and run create means
write to write and run programs computer
programs like Java parallel Python Ruby
PHP etc not only Java but our usage is
writing and executing Java programs say
Eclipse IDE it is also open source
Eclipse IDE is a platform to write and
execute computer programs computer
programs like Java for me next
Python Ruby PHP Xsara okay to write and
execute computer programs our usages
write and execute Java programs next
Eclipse IDE is open source open source
anybody can download and use next what
is the advantage of using Eclipse IDE it
provides editor for writing programs it
provides editor for writing programs for
overwriting programs next syntax
guidance syntax guidance next context
help context help next auto compilation
save if use Eclipse like like IDE you no
need to compile auto compilation got
this points meta auto compilation yes
sir next etc facilities
tell me good nod what is eclipse ID
eclipse ID is in eclipses chips ready
integrated development environment the
platform which right and it's good the
program's written in different
programming languages like Java Ruby
Python or PHP etc but our languages
writing and executing Java programs next
Eclipse IDE is open source next what is
the what of the advantages of Eclipse
IDE now it provides it's a miracle for
writing programs assets it provides a
plain text syntax guidance ur
protections context helps er content
auto auto compilation etc ok next steps
steps faster launch launch
Eclipse IDE observe Sanji de you need to
get me yes a create Java project create
Java project next under the project
create C we already discussed Java
program hierarchy in Java for selenium
chapter the last class creates a Java
package next create Java class or
interface see in this Java class you can
write your Java program and one more
thing under
under a Java project you can create
multiple packages if required under a
Java package you can create multiple
Java classes series of classes related
similar type of classes okay next next
write Java program write Java program
under run write Java program under on
just a minute okay just a minute again
miss Angie da same program I want to I
want to write and execute using Eclipse
IDE earlier we used a command line a
command command the problem ah continuum
No ah
launch eclipse ID yes
run ah is launching now ok larger honest
no new file new job
just a minute file new developer Java
project here enter java project name
suppose selenium tests finish project
created next select the project and
right click in old package for example
ABCD finish next select the package and
right click new okay
suppose sample sample
okay finish yes sir okay
suppose you can customize a Eclipse ID
suppose it is showing small fonts
observe how to customize window menu
preferences preferences general
appearance colors and fonts colors and
see colors and fonts edit suppose I want
18 okay
apply next
this is editor fonts this is console
fund console font next editor Java
editor edit suppose 18 okay
apply okay see you have to customize you
can customize the editor fonts as well
as console fonts output fonts also now
guide make you how to customize any
hello so can enjoy it again please
just a minute we can do this from the
preference our window window Meno
preferences just a minute
just a minute window menu preferences
now just the restore defaults why it is
not showing defaults window preferences
just a minute appearance colors and
fonts Java editor restore defaults now
10 apply next debug console font restore
defaults apply just a minute
okay
ah this is Baystate now you guide me
Neela three I want to increase editor
fonts as well as output just a minute
output first write the program then I
will show again main method public
static void main string s capital curl
square brackets orgs open curly braces
okay just a minute after class
declaration after class statement after
class statement public static void main
string square brackets orgs open curly
braces next write normal statements
suppose system dot out just a minute how
to dot println
it is providing context help context
help hallo
yeah just a minute
no need to compel just to run run okay
observe
Smith Knight is providing output on the
high D console anot system console Neela
Snell can you hear this output yes sir I
am able to you this is also small font
now yes sir
okay now guide me Neela 3 how to
increase editor and the output console
font size okay all you have to go window
way go reference preferences general
general on appearance appearance color
circles fonts colors and fonts absorbing
a first time selecting Java here select
Java editor yield here increase the font
size font style etc suppose 18 okay
applied next selected debug here select
console font edit suppose I want 18 okay
apply okay
now editor font size increased try to
run this one run this program absorb
console font also increase in on
hello user okay just a minute
suppose you create close this one you
create another program suppose in same
package ABCD new class suppose metha
here observe Smitha main method main
method is program execution starts from
main method 'no yes sir and it is
mandatory in every java program you can
type main method otherwise while
creating the class you can select a main
method here observe main method syntax
is there now is a public stock public
static void main string args it will
generate generated na yes just a minute
and you can type suppose system don't
forget about this shortcut case that we
will discuss later shortcut key for
display statement sy s ho control space
enter suppose hollow Java Hollow Java no
need to compile auto compilation just
run the program it is executing hollow
Java suppose I want to add one more Pro
one more statement I want to add one
more statement same display statement
this type are just a minute
hello selenium observes Angela no need
to compile yes sir
auto compilation you just execute the
program run yes hallo Java hallo
selenium Akana and one more thing if it
is not bad no context to help no syntax
guidance here it is observe
it is showing sin syntax errors nam yes
see observe the guidance change to quick
fixes change to println
this is syntax guidance syntax guidance
next context help suppose system dot
what is this what is this a venom can
take out this is context help nah listen
system dot here you can select if you
know the syntax out dot next println
println you do not concentrate on this
one for example
you can display variable value say first
statement message second statement
variable value Oh what is the output
Gounod what are the outputs hello Java
and so Joe one hundred one hundred good
hallo Java one hundred okay this is
about writing and executing program in
Eclipse IDE okay
tomorrow we will discuss this one Java
program structure that is separate
chapter in the chapter I will explain
Java syntax again and how to write
normal statements and first what is the
program structure next how to write
normal statements how to write code
blocks etc okay now
Smitha i am going to close the session
any queries regarding this class today
we discuss reintroducing java next write
and execute java programs are two
different scenarios one is using command
prompt another is using ide we used
eclipse ide in our training program also
we use eclipse ide not omit in hiring
program in real time also we use eclipse
ide with a selenium Oh Eric juarez said
when query sir ah in the Eclipse IDE you
like a new we by default will find the
Java project by divide it say in some
flavours of some flavors of Eclipse by
default you can find Java project
otherwise no issue you take other you
select other here
you can find different types of projects
there you can select Java project no
issue ah okay okay now say is of your
good question say in some flavor South
you are in some flavours of eclipse you
can find direct option new Java project
but in some flavours you don't find Java
project no no problem you just select
new other here you can find Java project
select Java project next and continue ah
any other queries thank you sir welcome
so Smith ah
Sangeetha pretty madhumathi I'm good sir
thank you welcome madhumathi here and
good says okay we're not Sam good sir
thank you okay welcome will make the
tomorrow same time thank you
