Selenium Quick Tutorial 4: Java for Selenium Part 2 Video Lecture | Selenium Test Automation:Tutorial for Beginners (English) - Software Testing

say Java quick tutorial for selenium
part to Java quick tutorial in part 1 we
discussed what we discussed first Java
environment setup Java environment set
up next Java fundamentals Java
fundamentals here we discussed the
writing comments comments in Java next
data types data types next container
Sridevi tell me the Java fundamentals in
sequence what we discussed in the last
class
Java data types next you continue
people buy nobody responding crystalling
intro Java modifiers next our variables
variables next operators in Java
operators next as flow control under
flow control conditional statements
conditional statements next loop
students loop structures or loop
statements next string handling a string
handling in Java string handling next
arrays in Java Java arrays next
operation IO operations input and output
operations okay these topics we
discussed in the last class next
continuation what are the remaining
topics for selenium next to file
handling file handling next job
methods Java methods first Java built-in
methods are predefined methods next Java
user-defined methods user-defined next
exception handling exception handling
say these are the Java fundamentals next
whoops object-oriented programming
concepts Java whoops be just a minute
first Java fundamentals than Java whoops
Java Oh PS oops transfer object object
oriented programming system or here for
fun
mentals of hoops what are they mother a
author inheritance inheritance
inheritance next polymer good
polymorphism next abstraction
abstraction abstraction last one not
good encapsulation encapsulation ok say
faster file handling file handling say
computer point of view everything is
file drive is file folder is file file
is file database also file database
files correct Tom sake the under user
point of view drives folders files
databases etc this classification but
computer understand things in terms of
files only computer point of view
everything is filed here how to handle
files using file class predefined at a
class using file class we can handle
computer files to just a minute using
file class file class we can handle
compute
files computer files say using using
this just a minute computer files using
this file class we can handle extra
files only folders text files but other
files what are the other files for
example Excel Word etc see if you want
to handle Excel files you need to
download third-party jar files Excel jar
files Word files for jars see this file
file class only for flat files drives
folders and flat files if you want to
handle Excel you need to download excel
jar and the addict next word or jars ok
anyhow that we will discuss later using
this file class we can handle drives
folders and flat files I will show an
example example create a folder create a
folder she launched eclipse create a
Java class suppose sample C check main
method it will generate main method you
know what is the purpose of main method
purpose of main method
Sreedevi purpose of main method in Java
see they were not responding Santhosh
purpose of main method in Java
programming Madhuri
principal purpose of main method in Java
programming yes to say you create the
programs you only get has become after a
shuttle method so rogue program
execution starts from main method
program execution starts from main
method okay create instance in file
class instance means object file this
file is predefined a class you take any
object name file object you can use ABCD
also equal to new keyword next class
name same file within parentheses and
double quotes path path for storing
suppose I want to store on desktop in
just a minute
desktop you take desktop path just
terminate
suppose folder named selenium are used
double backward slashes are single
forward slash semicolon import file
class from Java yo Java dot IO okay
next using this file object create
folder C file object dot make their type
iam select m'kay their semicolon auger
on desktop no selenium folder run the
program see observe principal selenium
folder create on desktop na yes sir
see this okay remaining examples we will
discuss in detail chapter here only
quick tutorial see file handling next
topic Java methods first predefined are
built-in methods Java built-in methods
Java built-in methods say a Java method
is a set of statements that are grouped
together to perform an operation a java
method is a set of statements that are
grouped together to perform an operation
methods are also known as functions
methods are also known as functions in
structured programming for example C
language we
functions built-in functions and
user-defined functions in
object-oriented programming example Java
language we use methods built-in methods
and user-defined methods getting this
point ma the way
methods are also known as functions in
structure programming example C language
we use functions in object-oriented
programming example Java language we use
methods okay when we choose methods
whenever we want to perform any
operation multiple times then we choose
methods C purpose of methods reusability
code reusability next we have two types
of methods built-in methods and
user-defined methods first I will show
some examples for built-in methods then
those are different methods see examples
for built-in methods see we have some
categories of built-in methods for
example string methods methods on
strings number methods methods on
numbers array methods methods on arrays
character methods methods on characters
see first I will show on string method
just a minute
string method string str1 equal to say
lynnium semicolon next spring str -
equal to
CAPITAL LETTERS selenium semicolon
string STR 3 equal to STR a spring name
you can use any name any meaningful name
selenium C spring is object in Java say
display suppose STR 1 dot equals method
this is built-in method equals STR to it
returns boolean result logical result
true or false
next sy as for control space enter short
form for display statement output
statement STR 1 dot equals str3 observe
Salani what is the first output string
one false hopes string one small letters
string 2 capital letters so false next
st over dot str3 true you run the
program
she falls true just a minute
this is this is an
sample for string method method on
strings next one number method rounded
for example what is this method equals
equals method next rounded method names
starts with small letters class name
starts with uppercase letter C round
method what is the what is the
functionality of rounds round method
rounds the value to nearest integer
rounds the value to nearest integer
observe suppose double data type double
a equal to ten point four five six next
double B equal to ten point seven five
seven six seven semicolon next output
statement here math math is built-in
class math dot rounded round off a next
at the dot roundoff B what is the first
output Sreedevi Sridevi can you hear me
yes sir I can hear himself what is the
first output around the value false
false not false it is value-based output
is logical outputs and ten nearest
integer suppose B below point five to
nearest integer 10 next second output 10
point five mm nearest integer 11 11 11
run the program
10 11 just a minute
observe Ravindra earlier we used a
method on string directly STR 1 dot
equals this time math dot round of hey
why the string variable string is object
but double data type is not object
that's why we are taking that math
built-in function support getting this
point Praveen draw say in Java
everything is object except primitive
data types integer double boolean etc in
Java
everything is object string is object
array is object everything is object
except primitive datatypes
that's why Java is not 100% whoops
hundred percent object-oriented
programming why primitive data types are
not
objects that's why here I used math
predefined at a class earlier I used the
methods directly y string is object but
double data type is not object next from
character function character function is
alphabetic is alphabetically what is the
functionality it checks whether the
value is alphabet or not and returns
boolean result logical result true or
false like sees example or declare two
characters care ei equal to single quote
this is Java syntax suppose Jade
semicolon next care be equal to single
quote suppose 1 you can use any
character alphabets or numbers are
special characters next display here
also character is not object it is
datatype primitive datatype so here I am
taking character character predefined
class character dot type I select is
alphabetic method next yay
next just a minute
B Saloni
the outputs but is the first output is
alphabetic are not you have to prove
just a minute
next be
false output true false expected output
true false okay just a minute
okay now Madurai are you following okay
next come to user-defined methods yours
are definer of ethics see anyhow it is
quick tutorial in detailed tutorial I
will explain each and every concept in
detailed manner here just overview
user-defined methods user-defined
methods here we have two types of
user-defined methods method with
returning value method with returning
value next method without returning any
value method with returning a value
method without returning a value these
are the two types of methods say I will
show example examples and one more thing
usually we call methods using object
calling methods by invoking object
without object also we can call methods
static methods only anyhow that I will
discuss later see in two ways we can
call methods not two ways if it is
static method without object we can call
if it is non static
method by invoking object we call here I
will show only non static methods in
user-defined methods chapter I will show
static and non-static methods here two
simple examples first create a method
with returning a value create a method
just a minute
create a method with returning a value
with returning a value and call the
method called the method by invoking
object by invoking object
Nadja first create a method for blake
you don't concentrate on the syntax that
we will discuss later suppose return
type hint method name multiply next
parameters int a int B suppose into C
open curly braces next I am declaring
one local variable int result next
result result equal to
plus B plus C not plus multiplication a
multiply B multiply C semicolon next
written a written result semicolon or is
the problem public and removing invalid
mother's what is the invalid modifier
here o method declaration before main
method method declaration before main
method next method calling after main
method okay next create object how to
create object class-name what is the
class name here sample class name
gnashed object name class name object
name you can use any meaningful name
suppose ABC are obj equal to new class
name class name is sample open and close
parenthesis semicolon next you can use
this object for calling methods how to
call suppose return returning type
integer now we have to store the value
equal to ABC Ossorio Vezina obj dot
method name multiply suppose 10 to
4c whenever you want to multiply three
numbers you can use this method if you
want to display X run the program 80
okay now Madhuri Madhuri okay okay cool
cool okay next observe ravindra here two
statements make it one statement make it
a single statement reduce the code size
without disturbing the functionality
progres Paul make these selected
statements into one statement single
statement without disturbing the
functionality reduce the core size and
here is what we call foreign you remove
this one and here enough now say clarity
point of view I use it two statements
single statement enough and one more
things Philemon here also 12 and 13 two
statements required suppose your your
interpretation is only displaying the
output only displaying the output use
single statement yes he same system that
all print line in object that multiply
good she want to display the value just
to use single statement
run the program same output but when
purpose is there if you store that value
into variable you can use that value
anywhere here only display okay now
principal so you see in the second
scenario two statements required why you
want to display the value you can use
single statement suppose I want to store
the value later later I will use that
value in another block of code that time
taking values in two variable is
mandatory now this okay next one more
method without returning any value
without returning any value suppose
public wide wide means return type
nothing public wide suppose I add open
curly braces next suppose int a equal to
10 B equal to 20 semicolon just a
display statement a plus B here no
return statement
J dot yard
here I didn't use parameters you can use
parameters no issue from the program
Tati method without returning any value
see here you can ask one question it is
written Athena that P is not returning
the value displaying the value
displaying is different returning is
different yes sir
so why did we display before here before
bad method before yesterday we put
system out before main method the
previous syntax we didn't put before
observe the system out system dot out
dot println method is part of this
method it was a define and method ok but
we are calling after main method now we
are calling that method after main
method only yes sir before main method
only declaration the system dot out dot
println statement is not independent
statement it is part of the C add method
it was a different method okay now focus
is recorded okay
next come to Java exception handling
Java exception handling just a minute
exception handling say an ax
is an event that occurs during execution
of a program when normal execution of a
program is interrupted exception
handling is a mechanism to handle
exceptions next common scenarios where
exceptions may occur common scenarios
where exceptions may occur one is
scenario where automatic exception
occurs next scenario where mullendore
exception occurs next scenario where
number four made exception occurs next
scenario where array index out of bounds
exception occurs these four are the
common scenarios scenario where our
thematic exception occurs scenario where
null pointer exception occurs scenario
where number format exception occurs
scenario where array index out of bounds
exception occurs remember these four are
thematic exception null pointer
exception number format exception array
index out of bounds exception I will
show an example for remaining I will
show one example for automatic exception
for remaining exceptions we will discuss
in exception handling chapter observe
example
say int a equal to10 next hint Bay hint
B equal to 0 0 also value next hint
result in result equal to EA by be a by
B observe of Salone something by 0 what
is the output something by 0 0 no sorry
that number will be the output 10
mathematics mathematics important for
conclude of programming see there is
something by 0 today Paul D job Philemon
it's only tonight we cannot divide by 0
I infinite now yeah so we cannot display
that one so our thematic exception but
it is not syntax error it is not showing
any syntax errors runtime error
see suppose selenium testing next
hello Java observe Sridevi in this
program
how many outputs are there in this
program
how many outputs Venkatesa pardon
puh
what about tenth align you have three
three outputs okay forget about
exception but three outputs but first
our problem problem in first output so a
rogram execution will be interrupted it
won't so second output and third output
say problem in first output but it won't
so remaining outputs why program
execution will be interrupted from the
program
observe exception here using try catch
block using try catch block we can
handle this exception can you tell me
prove a try catch you should write
open curly braces next catch catch after
10th aligned or after 11th line saluton
lanes closed catch braces and the last
operative night
here exception what is the what is that
exception
exception what type of exception are
automatic nah ultimate is just a minute
automatic exception the automatic
exception arithmetic exception suppose
exception a me any meaningful name you
can use what is the problem
spell mistake exception okay spell a
spelling mistake next error handling
code error handling code
okay yeah you can use any meaningful
statement around the program
observe observe siddaway
first output error but it is showing
remaining outputs na means complete
program executed now this time Hodder a
moderate this time complete program
executed now but it is showing second
and third outputs but earlier earlier
program execution interrupted ok knob
Madhavi did you follow this one
Ravindra okay next come to Java whoops
be Java oops we have four fundamentals
of hoops now first I am taking
inheritance inheritance
what is inheritance inheritance
inheritance means reusing it is a
process of inheriting inheriting means
reusing the class members it is a
process of inheriting the class members
from one class to another class members
what are the class members variables and
methods variables and methods are known
as class members
it is inheritance it is a process of
inheriting the class members from one
to another next the class where the
class members are getting inherited he
is called as superclass or parent class
our base class see once again
the class where the class members are
getting inherited he is called as parent
class or superclass or base class next
the class to which the class members are
getting inherited is called as subclass
or child class or derived class next the
inheritance between super class and
subclass or you can say parent class and
the child class is achieved using he
extends keyword he extends also the
example continue see once again
inheritance is a process of inheriting
the class members from one class to
another see example first create a class
suppose select package new class class a
class a
Class A here create a method create a
method before that just a minute
int a equal to 10 ain't be equal to 20
just variables next method public wide
public void add open curly braces next
just a display statement a plus B next
create object create object in order to
call the method
tell me Madhavi create object how to
create object how to create object in
java
Saloni yes
create object in this class classy
classy you know the syntax class name
yes name than any name any meaningful
name any name for object suppose le b c
equal to new keyword class name what is
the class name classy a open and close
parentheses semicolon next a b a b c dot
what is the
name IRD run the program it is showing
output now oh okay
next create one more class class suppose
class name Class B Class B next inherit
reuse class members from glossier how to
inherit using a extends keyword extends
Class A in this scenario which one is so
so per class which and which which is a
subclass Sridevi identify the parent
class and a child class which one is
parent class B are Class A Class A is
the parent child
okay now I want to access method from
class ii a parent a class a create
object you know how to create object
class b next XYZ equal to MU Class B
Class semicolon and this makes the
access than one XYZ dot yeah I did see
this XYZ method is not available in
Class B but available in parent class we
are accessing we are realizing we are
reusing the method from parent class
from the program getting the output now
yes suppose you know just terminated in
the child class also same method
available int a equal to 100
in to be equal to 200 next public wide
he had open curly braces next display a
plus B then what is the output C say
method method overriding this concept is
called method overriding same method
awell same method name available in
parent class and child class that time
first priority goes to local class first
priority goes to local class run the
program 300 suppose here no method no
add method just a minute then it will
access that the add method from parent
class Praveen draw D to understand this
concept so same methods available in
parent class and child class that time
first priority goes to local class local
class suppose I want to access parent
class method only in the child class
also same method same method available
but I want to access parent method
parent class method only then how to
access or you create a object using you
create object using parent class name
glossier next obj to equal to new
see a next obj2 dot he had supposed
meaningful name use meaningful name obj1
obj2 on what is the first output 300
second output totty totty rhonda progra
and just a minute run the program 330
observe principal no no add method in
local class then what are the outputs 32
outputs
totty totty totty totty 'no yes sir okay
just a minute
Santosh did you understand the concept
look at the soil class real class local
class means where we are executing the
programs in held class only just
terminated anyhow it is brief idea this
is class 1 all of you put note class 1
next class two
okay next polymorphism polymorphism
polymorphism what is polymorphism
existence of object behavior in many
forms existence of object behavior in
many forms there are two types of
polymorphism in Java one is method
overloading
another is method overriding method
overriding first one method overloading
next method overriding what is method
overloading if two or more methods with
same name in the same class but they are
different following ways number of
arguments are type of arguments observe
method overloading if two or more
methods with same name in the same class
but they differ in in the following ways
one is a number of arguments are type of
arguments next method overriding if two
or more methods in the if two methods if
two methods that are available in parent
with same name if two methods with same
name that are available in parent class
and the child class that is method
overriding earlier we discussed observe
ravindra earlier in inheritance Descanso
overriding now
two methods two methods available in
parent class two methods with same name
available in parent class and child
class observed in the previous example
yard method available in parent class
and the child class if two methods with
the same name available in parent class
and child class that concept is method
overriding next method overloading
prevent row
what is method overloading you know two
or more methods with same name different
child class if two or more methods with
same name in the same class but they
differ in following ways number of
arguments are type of arguments observe
protocol in method overloading single
class only yes or more methods with same
name in the same class that is method
overloading next method overriding two
methods with same name that available in
parent class and child class method
overriding indirectly we discussed in
previous example next I will show one
small example for method overloading
okay now yes sir okay observe observe
okay suppose Class C create two methods
with same name just a minute
suppose public void he had int a int B
open curly braces next display a plus B
next one more method two or more methods
suppose you add if he's showing a it is
showing a syntax error
why same name duplicate duplicate names
not allowed but if you use a number of
arguments different number of arguments
or type of arguments then it will accept
for example just a minute
double ee8 next
BB w a BB next in C observed Madhavi in
this class I created three methods three
methods name same ma FF but difference
is their custom method two arguments
integer type arguments two parameters
integer type parameters second men
second method also two parameters but
double type an external hard one integer
type only but three parameters okay now
just a minute call you know how to call
these non static methods by invoking
object first create object class-name
see obj equal to MU class c open curly
braces close semicolon next open a dot
suppose yadda based on values
for parameters based on values for
parameters it will call that method
observe suppose I am using one point two
three four comma three point four then
it will call this second method next obj
dot he had off suppose 10 comma 23 comma
45 next obj dot add suppose 10 comma 70
run the program
Sreedevi observe
he's showing three outputs now method
overloading yes sir
sir if you put one more sir called
method like a three-digit ah what will
happen if you if you call one more
method with 300 years three integers
already we call it na so if we call one
more so like not one more you can you
can call thousand times same out of
orbit otherwise you can is different
output different parameters suppose one
two three one two three okay now user on
the program see trying output na six a
useful method functionality is primary
purpose of methods is reusability you
can reuse the N number of times no
issues okay so n number of times
okay good question you can reuse methods
n number of times once you once you
define methods once once you declare
methods then you can use n number of
times before moving to next topic just
to prevent route just to tell me what is
method overloading and what is method
overriding
method overloading
don't confuse
Santhosh two methods - are more people
to - are more monsters methods having
same name in the same class but they
differ him observe ravindra now don't
confuse method overloading single class
method overriding multiple classes
observe method overloading if two or
more methods not only two who are more
methods in the act in that previous
example i used three methods if two or
more methods with the same name in the
same class but they differ in number of
arguments or type of arguments that
concept is called method overloading
next method overriding Madhavi method
overriding having multiple arguments in
the same class but they follow said
methods overriding to class having two
or both if two methods with same name
that are available in parent class and
subclass or child class is called method
of overriding observed just a minute
just a minute
method overloading continued
what is method overloading if-if-if
methods for two or more methods same
name with same name in same class ah
with same name in the same class
say what yeah but they're different but
but the different number of arguments
and type of our words but they differ in
one is number of arguments number of
number of arguments are okay just a
minute but they're different number of
arguments or type of arguments or type
of arguments
if two or more methods with same name in
the same class but they're different
number of arguments are type of
arguments this concept is called method
overloading next method overriding if
two methods two methods with same name
that available available in parent class
parent class and some child class are
subclass sail'd class
this is method overriding okay nicely
they win any confusion no sir
Pradeep all are following the world okay
cool next abstraction say we discuss the
inheritance polymorphism next third one
abstraction
abstraction what is abstraction it is a
process of hiding implementation details
and showing only functionality to the
user actually this abstraction is not
required for selenium testing is only
for Dowell of ours
okay concept is there I will explain it
is a process of hiding implementation
details and showing only functionality
to the user we have two types of methods
in Java one is concrete methods another
is abstract methods she observed earlier
we discussed two types of methods one is
method with returning a value another is
method without returning without
returning any value that classification
is different that is general
classification in this scenario means
abstraction scenario we have two types
of methods say based on the scenario
earlier we discussed two types of
methods method with returning a value
method without returning any value that
is general classification this is
another classification abstraction point
of view we have two types of methods one
is concrete methods another is abstract
methods concrete methods means the
methods which are having body abstract
methods means the methods which are not
having body see I will create one
abstract class in abstraction chapter I
will explain all concepts related to
abstraction just I will create an
abstract class abstract class having one
or more abstract methods
suppose I'm taking this class C Class C
say public or just omit take new class
suppose class name bikes class name
bikes
classname bikes suppose public wide
handle display bikes bikes have handle
observed Maduri is it concrete method or
abstract method I think
great method is complete method next
seated open curly braces see bikes bikes
have seed this is also concrete method
next public wide wheels open and closed
parenthesis semicolon this is abstract
method observed quick fixes add body
otherwise change bikes dot wheels to
abstract this abstract method suppose if
any one method in the class is abstract
then class also abstract abstract
observe this is abstract class means
incomplete class in this class to
concrete methods and one abstract method
available next how to reuse methods from
abstract class that I will explain in
Maine chapter now I just showed this one
how to create concrete and abstract
methods abstract class creating abstract
class
next and one more thing try to create a
object try to create a object Saloni try
to create a object
buycks obj equal to new my new bikes
semicolon
still error what is the problem we
cannot create instance our object in
abstract class getting this point pretty
ball we cannot create object our
instance in in abstract class then how
to access abstract how to access methods
from abstract class that we will discuss
in main main chapters next one more
thing is there a encapsulation small
topic encapsulation actually this
encapsulation also not required for our
test automation is only for dowel of
ours okay in Maine chapter I will
explain encapsulation also first of all
what is encapsulation it is a process of
wrapping code and data into a single
unit it is a process of wrapping code
and data into a single unit is called a
encapsulation on general example for
encapsulation capsule medical example
capsule capsule ease mixer of several
medicines
next encapsulation is the technique
making the fields in a class private and
providing access way a public method
what is the advantage of encapsulation
it provides control over the data we can
make a class read-only our right only
see for security purpose we use
encapsulation anyhow it is it is used it
is used for developers only in selenium
testing we do not use this concept
observe people what is the encapsulation
so it is the wrapping the code and
methods wouldn't data not moving it
wrapping code and data into a single
unit what is the advantage of
encapsulation it provides control over
the data next we can make a class read
only or write only okay example my
example I will show in a main program a
main class it is only overview okay this
is about Java for selenium trick
tutorial just a final conclusion say we
already discussed it how much Java is
required for selenium C Java is version
all Java concepts are not required for
selenium how much then how much Java is
required for selenium core Java is
enough advanced Java is not required see
we can segregate Java for selenium into
two categories one is Java fundamentals
another is Java whoops
core Java is enough for test automation
advanced to Java is not required we
discussed all core Java concepts Java
fundamentals
and Java whoops next in these
fundamentals and whoops also I will
explain in brief usage comments comments
shall we use comments in our selenium
test cases pretty pal yes sir we do
sometimes just like a - more more clear
yes say yes I think comments is not
mandatory tasks but if you write
meaningful comments that is best
practice coding standard anybody can
understand program in our scenario test
the case in in our test cases if we
write comments then anybody can easily
understand the test case okay now next
data types we use or don't use use yes
use data I've seen test automation most
of the time we handle data different
types of data for storing and operating
data data types required next of
modifiers just modifiers limited use or
no use say modifiers is required for
modifiers are required for developers
they use public private protected etc
security point of view in our test
automation most of the time
ninety-nine percent hundred percent we
use public modifier only our system work
we share all resources to all team
members getting yes security so for most
of the time 100 percent we use public
access modifier only getting this next
another modifiers are then
access modifiers man access modifiers
Adama yes sir Amana we use a non as
small fares for example static modifier
is there we use static modifier for
creating static methods and static
variables hitting next one more most non
non access modifier final modifier is
there you use final modifier for
finalizing the value variable value okay
limited use modifiers limited use see we
have two types of modifiers access
modifiers non access modifiers most of
the time we use public access modifier
only usually we don't use private
protected etc access modifiers next
another type man access modifiers we use
a non access modifiers static modifier
we use static modifier for creating
static methods and static variables next
final modifier for finalizing variable
values etc next what about variables
prevent route we use or don't use in our
selenium test automation functional test
automation using selenium we are using
yes we use variables for storing and for
storing the data next three they way
operators we use or don't use operators
we use our projection for mathematical
calculations operators mandatory for
mathematical calculations our logical
logical comparisons etcetera we use
operators next Madhavi conditional
statements and we used in affiliation we
use conditional statements for example
for to insert verification points to
instruct verification points
and for error handling we use
conditional statements next loop
statements Saloni loop statements yes or
we use yes we use loop statements for
repetitive execution next string is
strings it is more important for our
test automation whenever we read data
then computer program conscious the data
a string type data so strings we use
arrays limited use are no use limited
use for reading data from excel file we
use array limited use next i/o
operations we use Ocana principal
input/output operations
Santhosh IO operations is it useful yes
in our test automation or not we use
next file handling Solomon file handling
sVU's file handling safe or debt order
one testing we work with the text files
Excel files etc file handling we use
next built-in methods sridevi so we use
those methods for handling for operating
strings numbers characters arrays etc
next those are definite methods we use
user-defined methods we in our cases if
you if you find more reusable components
if we find more reusable components then
you can reduce the code size in our test
cases we use user-defined methods
exception handling yes we use exception
handling next
what are the remaining whoops
inheritance yes we use inheritance for
reusing class members polymorphism
limited use usually we don't create
methods with same name
he finished scenario is therefore
creating methods with same name then we
use polymorphism limited use limited use
inheritance use polymorphism limited use
abstraction principle I think knowing so
whose encapsulation no use
