Java Tutorial 9: User Defined Methods in Java Video Lecture | Selenium Test Automation:Tutorial for Beginners (English) - Software Testing

selenium class 13 Java methods
user-defined methods say first chapter
index today we are going to discuss
three topics introduction to Java
methods introduction introduction to
Java methods next types of methods types
of methods say we have two types of
methods built-in methods and
user-defined methods today we will
discuss user-defined methods today we
will discuss your different methods
tomorrow built-in methods see
user-defined methods heõs or define our
methods say this is the today's agenda
introduction to Java methods types of
methods user-defined methods see first a
topic introduction to Java methods
introduction to Java methods say first
of all what is method for the problem
pretty okay okay
what about you
okay what is okay pretty what is Method
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 next methods are
also known as functions in structure
programming example for example C
language we use functions in C language
no method concept no method a Tarma only
function in structured programming for
example C language we use functions
built-in functions and user-defined
functions in object-oriented programming
for example in Java language we use
methods built-in methods and
user-defined methods sake a java method
a java method is a set of is a set of
statements or steps is a set of
statements or steps or instructions that
are grouped together that are group put
together to perform
an operation to perform an operation
next methods are also known as functions
in computer programming methods are also
known as functions methods are also
known as functions next point in
structured programming in structured
programming example C language in
structured programming we use okay
dollar pursues we use functions two
types of functions built-in functions
built-in and yours are defined euros are
defined it belton and yours are defined
next in object-oriented programming in
object-oriented oriented programming for
example Java language just a minute Java
Java language
we use methods methods here also say
methods basically two types of methods
built-in are predefined methods and
user-defined methods those are
definitely built-in methods limited
read-only but yours are defined methods
unlimited you can create a number of
methods and you can edit user-defined
methods okay okay now Gounod Natarajan
Gounod it said I am able to hear you sir
yes sir I understood sir okay cool
say first of all when we choose methods
when we choose methods method just guess
method is reusable component reusable
code method means is a reusable code
when we chose methods when we need to
perform the action multiple types are
good whenever we want to perform any
operation multiple times then we choose
methods instead of writing the same code
again and again we choose polychaetes
next what is the advantage our purpose
of methods code reusability using
methods we can reduce the project code
size see when we choose methods when we
choose methods say whenever whenever we
want to perform any operation any
operation say method is technical term
business term is operation whenever we
want to perform any operation multiple
times multiple times in the same class
our other classes multiple times then we
choose methods then we choose methods
next advantage of methods advantage
advantage of methods code reusability
code reusability say using methods we
can reduce the core size we can reduce
the code size project core size project
codes we can read just a minute miss
placement we can reduce the project code
size suppose for one project total
suppose 100 classes hundred programs
5,000 lines if we use more reusable
components if you find and use more
reusable components definitely you can
reduce the code size this is one primary
advantage any other Rahman Muhammad
Rahman any other
there is a code reusability and who have
the reduced of course I didn't reduce
the code size okay if you reuse
definitely you can reduce the code size
one more thing is there maintenance is
easy na yes
code maintenance supposed on
functionality are one operation is there
you are using that operation in you are
using that operation multiple times
suppose seven times in your project
whenever any changes are there in that
operation just to change at one place
that can be reflected to all classes
where you are using that operation say
maintenance is easy C code maintenance
code maintenance is easy easy to
maintain these two are the important
advantages of methods code reusability
so that you can reduce the project core
size next maintenance easy modifications
easy okay
next C this is the bridge
introduction about methods next types of
methods we already discussed there say
we have basically we have two types of
methods basically we have two types of
methods what are the two types of
methods Sunil Sunil yes sir what are the
two types of methods concentrate observe
this line until netted in
object-oriented programming for example
Java language we use methods built-in
and the other define it but how many
types of methods basically we have two
types of methods what are the two types
yes types are two types of methods two
types of methods one is built-in
built-in or you can say predefined
methods predefined added methods these
are read-only you cannot edit the code
you can use as it is and one more thing
that method names also standard you
cannot change the method names if it is
user defined method you can use your own
names and you can change the method
names also next user-defined methods
user-defined methods see these are the
two types okay I will provide brief
introduction about built-in methods
tomorrow we will discuss built-in
methods today user-defined methods see
just a brief introduction built-in
methods say Java has a library of class
and methods organized in packages Java
Java has library of classes library of
classes and methods organized in
packages organized in packages Java has
as a library as a library of classes and
methods organized in packages for
example I will package Lang package C
Java dot IO dot for example console
console observes meta this is built-in
like a built-in library
what is this Java project what is this I
bow package package
what is this console class see we are
importing just just we write import if
you want to import this one import
import keyword Java dot IO dot console
what is the functionality of the
statement we are importing console class
from IO package under Java project
suppose
or not I want to import all classes from
io package all classes not only can
whole class our second import Java dot
IO dot - console dot asterisk control Y
console yeah I or dot Java dot IO dot
restriction first dot hostak a followed
by a semicolon semicolon enough say next
in order to use built-in methods we need
to import packages or classes particular
classes say in order to use in order to
use built-in methods built-in methods we
need to import import packages
yes
yes suppose you want particular class
you can import our entire package you
can import next Java dot lang package is
automatically imported to your very java
program this is automatically imported
to your Java program
you no need to import say Java dot
language footnote somebody's to
mechanize packages automatically
automatically imported imported to
imported in every Java program every
Java program next using import keyword
we can import packages or classes using
import keyword don't write double course
in programs just understanding purpose
easing import keyword this is Java
keyword or reservoir word we can import
package
yes packages one by one or classes say
we have some categories of built-in
methods our test automation point of
view for categories are important see
categories of built-in functions
built-in methods categories of built-in
methods on his important 1 string
methods string methods methods on
strings operations on strings next array
methods array methods operations on
arrays next number methods operations on
numbers next character methods character
methods methods on characters etc see
this is a brief introduction about
built-in methods we'll discuss tomorrow
now come to user-defined methods see
thought topic user-defined methods just
a minute this is second one types of
methods
just a minute yours are definer methods
say we have two types of user-defined
methods two types of user-defined
methods what are the Raman two types of
user-defined methods method with turning
value a method without returning any
value good see two types of user-defined
methods one is method without returning
any value see just a performing
operation no value returning see method
without returning without returning any
value next method with returning value
method with returning value a returning
value
say first one only performing operation
second one performing operation under
returning value method without returning
any value method with returning value
okay
next again calling first one method
without returning value calling two
types so can you repeat the question
method without returning value and
method which returning only what's the
difference if you say something without
returning any value means only
performing operation no value written
method returning value means performing
operation under returning value say call
say calling two types see this is
defining defining next calling are
creating method creating method method
without returning any value next calling
two types calling can you tell me are
the calling two types creating method
creating method method without returning
any value that is one type method with
returning value that is another type
first I am taking method without
returning any value this is creating a
method next calling two types you can
call that method in two ways tell me
Aarthi Aarthi
baby it's a call-by-value
call-by-reference
baby well that is a different one raha
maan sir
calling method by invoking a object
without invoking object good say in
order to access methods in order to
access methods are in order to use
methods object required object 2.2
method that is the syntax object data
method without object also you can call
methods one is calling method calling
method by invoking object C calling
methods by invoking object another one
calling methods without invoking object
calling methods without invoking object
next same method with returning a value
also same calling methods by invoking
object and calling method without
invoking object okay next one more
flavor also there that is also calling
point of view not creating point of view
calling external
there's external methods say first first
to calling methods in the same class
creating and using within the class here
external suppose in the first in the
class one we have some methods want to
use those methods in class two you can
use calling external methods of our
internal methods what is the internal
method Smitha here another
classification another classification
internal method external method what is
internal method and what is external
method internal method is without
written no nella three internal method
external method another classification
which is inside any particular class
inside class inside term confusing
creating and using methods within the
class suppose in the same class create
method and use that is the internal
method net external method means calling
from external classes other classes any
confusion Smitha re following or any
confusion can you please repeat the
internal method internal method suppose
class one class one I created two
methods in class one and I am calling
those methods in class one only class
one
means creating and calling within the
same class those are internal methods
suppose I am calling these methods from
another class class to class to point of
view class one methods are external
methods now
yes sir those are external methods any
confusion Nayla 3 no sir I will provide
examples then you can get more clarity
say in this today's class I will
introduce methods syntax with example
again in selenium webdriver
module we use user defined methods again
we will discuss but that is testing
point of view this is general see today
general overview next in selenium
webdriver module again we will use
user-defined methods okay first one
first one I am taking returning value
writing overwriting methods for writing
methods with returning value with
returning value returning value what is
the advantage of returning value rahman
suppose only performing operation that
is one scenario performing operation and
returning value that is another scenario
what is the advantage of returning value
value so we can use it you can pass the
value 2 you can pass the value two other
methods are you can explore
the value to external files hitting this
point we generally we store we store
returning value to variable variables
can be exported say you can export the
value that is one advantage next primary
advantages you can pass the value to
other other other methods observe
Smitha suppose login login method is the
testing point of view login method is
there just the performing login
functionality just the performing login
functionality okay the enter user name
enter password click default button
logon war only operation he had no
returning value next another scenario
performing operation and returning value
suppose after entering login after enter
after entering username and password
clicking on default button login
successful then return that value login
successful I want to pass that value to
next function next to method next method
is logout method our create vendor or
any other method after login successful
only I want to execute next method I can
pass this value this output to next
method hitting this these two scenarios
one is only performing operations
another is performing
operation and lessening value what is
the advantage of returning value the
value can be passed to the other class
other not other class other methods
suppose one method input is output for
next method that time you can fast not
yes say faster writing methods syntax
right method
oh right method observe soon L we define
our right methods before main method
getting this point he said that is rule
before main method
not after main method say we write
methods before main method next call
method right methods before main method
call methods
Smitha call methods before main method
are after main method after weather
after main method after main method C
program execution starts from main
method after main method these are rules
okay first override methods
syntax syntax follow the syntax axis
modifier access modifier if you don't
specify access modifier then RT RT not
responding tell me if we don't if you
don't use any access modifier then can
you tell me
Sridevi we disagree yeah public is
access modifier okay suppose if I don't
specify any access modifier then what
will happen so by default it will accept
it will considered as public no that is
in VBA scripted in vbscript default is
public but in Java ah Rahman in Java
what is the if you don't if we don't
specify any access modifier then what
will happen
nobody responding ah leave soon a
correct answer
default C we have for access modifier
public private default under protected
click on specify any modifier dipwad
ferries default default okay C access
modifier next return type return
I say datatypes
not only for variables we use data types
for constants and methods also method
with returning value here this method
when to return value so return type
required this is data type next method
name method name next parameters
parameters parameters optional if you
don't use any parameters use blank
parent this blank suppose I want to use
two parameters user ID password user ID
comma password see by separating with
commas you can use n number of
parameters open curly braces close curly
braces say next method body here you can
write statements every normal statement
should end with semicolon say what
programming features we use in main
program all can be used in methods also
see in methods you can use conditional
statements loop statements operators
variables all all programming features
can be used within the methods also next
calling calling
first the syntax writing method next to
syntax calling calling for calling
methods object required first create
object create object how to create
object class-name class name next object
name object name your own you can use
any meaningful name equal to new keyword
again class name semicolon next call
methods the class name object name new
them class name the last class name it
is modifier constructor white foreign
the like first this class name then
object him equal to new class name hmm
the last class name is construct away
call methods call methods by invoking
object by invoking object say what is
the syntax here returning the value na
datatype returning the value for storing
the
value variable required variable name
equal to object dot method suppose if we
use any parameters values values for
parameters semicolon if you don't use
any parameters leave blank or if you
want to display directly suppose if you
store in two variable you can export
this value or pass this value if you
want to only display that value you can
directly display system dot out dot
println of object dot method semicolon
semicolon syntax for example example
create a class suppose in this Java
examples XYZ da pack XY JD a package
create a class class name supposed Java
methods Java methods generate main
method okay
say
Smitha gave me before main method I want
to create a method I want to create a
method that method functionality is
multiplied three numbers create a method
for multiplying three numbers any three
numbers calling time we pass values
observed okay see those are the finer
methods he was our defining methods what
is the problem pretty system dot out dot
println
that is only displaying purpose if you
want to pass if you want to pass the
value or export the value taken to
variable forget about that second usage
take into variable that is the correct
syntax you leave this one forget this
one correct syntax is data type variable
name that is the syntax if you want to
display or if you want to pass the value
this is the syntax any confusion forget
about the display this is the calling
calling methods by invoking object
method with returning value you can
display the value otherwise otherwise
you can pass the value preethi are you
following see you okay you you try to
use proper wise device okay at least by
tomorrow or say
for example public okay pretty int
datatype I ain't supposed method name
multiply okay now open paranthesis
suppose int a say for parameters also
datatype important datatype mandatory in
to be hint see not only in da intervene
c can use XY Jade also ok Here I am
declaring one local variable end result
equal to ei multiplied B multiplied C
semicolon next return return keyword
return result semicolon see whenever you
want to multiply three numbers any three
numbers you can use this method okay
today I will explain methods with
mathematical values increased automation
chapters we will use test operations
here only mathematical values see this
method for multiplying three numbers any
three numbers okay continuous method
call this method in the same class for
calling method we need to create a
object now create the object faster
create object say object creation
one-time activity suppose in our class
10 methods are there only one object
create one object
and I access all ten methods one by one
create object you continue Sunol you
know how to create object we discussed
that syntax yes mmm that is not that is
calling create object class-name class
name is Java methods Java methods and
object name object name any name suppose
a B C and Java methods open open ba this
semicolon just a minute sensitive
okay object created next call methods
gonna call methods
this method is a returning value call
you know the syntax Nell Adri continue
yes what type of method what is the
method type method returning type we see
dot just a minute what is ABC that first
return type data type require not it
returns value na what type of unit what
is that what is the method type what is
the method data like in so use same same
method same data type int suppose he X
equal to our method ABC
dot what is that method name type IAM
multiply here it explains ABC provide
values suppose I want to multiply 10
comma 25 comma 35 semicolon next if you
want to if you want to pass that value
you can use X variable or if you want to
print that value same run printing now
that value Smitha yes sir
say this is method with returning value
next by invoking object say they are you
following any confusion spheres next
same method with returning value this
time without object without object
without object
yes terminate
method method with returning value
method with returning value and call
call the method by invoking object by
invoking object this is one type for
this we discussed the syntax as well as
example next b-1b method with returning
value and call the object called the
method without object
don't confuse first one method with
returning value and call the method by
invoking object next one method with
returning value and call the method
without object without object say for
this syntax writing methods syntax
common just the calling only different
calling only different say writing
method same calling only different can
you tell me writing method same Rajamani
writing
same syntax access modifier return type
method name next method name parameters
in the parameters parameters optional
open curly braces next statements next
close curly braces next colleague rahman
calling methods without returning
without written without object calling
methods without observable data type
then variable variable name equal to
variable name equal to mass of them
method name direct method name object
method object without object know just a
method name tell me Rahman
the method name juster may also say
method same calling only different you
can use the same example
Oh
the variation in syntaxin oh I didn't
forget one thing
syntax some difference is there
different syntax observe non access
modifier is required non access modifier
see access modifier non-access observe
RP intact some differences that if it is
by invoking object access modifier
return type method name if it is without
object access modifier non access
modifier return type method name
parameter statements close ok observe
here not a small affair we need to use
static modifier what is the purpose of
static mode fair what is the purpose of
static modifier Sreedevi recollect that
static modifier in modifiers modified
using object we can invoke method yes
without using any object we can invoke
methods we can use methods that is the
functionality of static modifier see for
main method also we are using static
okay now X equal to Java methods dot
multiply observe the set now now you
tell me the syntax neela 3 calling
methods without object
we're dead a variable name equal to
their work was cosmic class Magnum
class name just a class name dot method
method if available parameters using
class name we call static methods
observe class name
then 25 put mute 35 semicolon Aaron okay
now
Smita yes sir sir this is Brad can you
please once more please quickly
I got country Celica so we're just a
minute here two scenarios just a minute
observe do not those are defined methods
basically two types first type is what
is the first type method with a
returning value for example method with
returning value it is returning a value
suppose this is one one type of
user-defined method okay next next you
can call this method in two ways
what are the two days by invoking object
by invoking object located another way
without without object
okay now yes sir a subversive by
invoking object
to see creating method next a calling
method
creating calling one is by invoking
object without invoking object here are
creating methods also syntax difference
suppose creating create methods methods
first syntax this syntax for this syntax
for okay first the syntax here call
method by invoking object I am going to
call this method by invoking object
syntax vary on tell me the syntax access
modifier access modifier return type is
equals to become method name return type
next method names method name method
name parameters in the optional things
are optional parameters yes open curly
braces next state nominal statements
using next close curly braces next they
say I this is the syntax for creating
method next calling method call first
create object you should create object
how to create object class-name trust
him object name is supposed to class
name object name is equal to nu + o new
class name is a new class name
okay is a semicolon next create object
call method data type serve on data type
variable name variable name is equals to
object is equal equal to object dot
method suppose we use any parameters
pass values values semicolon over next
suppose same call method say same just a
copy this one okay so called method
without object without invoking any
object without call method without
object here just syntax of access
modifier non-access
non access modifier here we have to use
static static non access modifier what
is the formality of static already we
discussed in Java modifies chapter if we
use the attic without invoking any other
of you can access the method this is the
only only difference in syntax next to
here call method you no need to create
object you no need to create object
just calm method data type variable name
next object
class name dot method dot method i any
confusion you know solution think Snell
following these two to two different
flavors one a 1 B 1 a by invoking object
1b without invoking any object okay
next second to writing method of writing
methods without returning any value only
performing operations without returning
any value okay here also same two
flavors what are the two what are the
two flavors ramen one is by invoking
object and another one without invoking
object call method by invoking object in
working object next bees call methods
you can call multiple methods one by one
call methods by Col methods without
invoking without invoking object.observe
abs our own Ella three in the first one
also with with returning value without
returning value next we threatening
value by invoking object without
invoking object next without returning
value also in working up by invoking
object without invoking object to to to
into to total for now
yes sir say first call methods by
invoking object first syntax syntax for
creating methods first creating syntax
for creating methods observed here a
access modifier notic written type not
required return type not required
observe Aarthi have no returning value
not yes see access modifier access
modifier next a return type nothing
written type nothing next method name of
parameters parameters optional open
curly braces close curly braces next
statements
statements written type nothing next
Ramon you tell me the syntax part
without invoking object without invoking
object access modifier access modifier
known extras molecule on access modifier
yes without invoking of this non access
non access modifier written at nothing
return type nothing return type nothing
metal emblem Latin name open paranthas
parameters open curly braces statements
okay
next close curly braces next nail odd
recalling creating methods for creating
method purpose by invoking object second
one without invoking object next call
create object create object create
object create object you know how to
create object we already discussed it
next to create object what is the create
object name object name new q equal to
new keyword new keyword last name again
class name open and closed parent this
semicolon
okay next call
the desert no datatype
without returning any value not okay
just the object dot dot network method
kilometer parameters here we have to
pass values for parameters values
semicolon here only performing
operations no returning value
Tsun Tsun l4 second one without invoking
object without invoking object we
already used a non access modifier tell
me the calling directly the authority
required although they rejected yellow
brianza he had no datatype no returning
value only performing operation how do
you call with no returning value and no
object also directly directly how to
call class name ma yes new class name
new occupation class name have no object
no object no returning value class name
and thought method
suppose if any parameters of their
values okay now these four syntax s is
Smith are you following any confusion
yes sir okay I will show the example for
second one as metha how to guide me
pose first define method create method
create great a method without without
returning any value only performing
operation observed what is the syntax
access modifier public for example
public next static static not refers to
first by invoking object by invoking
object next without invoking any object
just return type nothing
what is the keyword for written type
nothing is one keyword what is why she
observed in in main method also we are
using that one wide wide next method
name method name for example student
rank student rank suppose end marks in
marks observe here no return keyword in
this method suppose I am writing on
condition F if
marks if marks greater than are equal to
600 then display the display ranky rank
e next yell safe marks greater than or
equal to 500 open curly braces then
display rank b rank b
next suppose else else rank see put me
out rank see see see somebody's to make
nice Howard upon echo coming with the
system ok observe madhumathi not
madhumathi Smita see this is this is the
method we created one method method
without returning in any value and and
we are going to call this method by
invoking object
ok now create object after main method
see create object here class name is
Java methods quick any problem
Smitha you continue Snell yes sir ah she
sank several times we discussed the
syntax where you are confusing just a
minute our thing continues Finella
class name student
Java methods next object name
engineering suppose woe be J equal to
new class name in Java methods meters
semicolon next call call that method
without returning value okay how to call
here without returning of a value so
without returning any value now you no
need to take any variable it's just
object job object object object dot
method object dot method what is the
method name student rank suppose marks
700 enough it will it will perform that
operation it will present acts okay
object method okay what is the output
are they observe the method
what is the output ranked reggae Frankie
C say rank II suppose 550 rank B suppose
450 rank see see this is about creating
and calling Smith are you following oh
just a minute this is for yeh yeh
example Smith are you following yes sir
our next second one you gave me call
method call methods without invoking
object for that creating methods syntax
different call methods in calling
methods syntax also different you
observe you observe two to two important
things one is without returning value
another is without invoking object
okay now previous of previous example
without returning value by invoking
object this example without returning
value without in working object here
syntaxes access modifier next non access
modifier require now what what is that
an access modifier
troit wide is not access modifier why it
is written type nothing read it
attic static static next here object no
object require now call method how to
call method without without object
it's a met him using class name Java
methods is the class name dot method any
confusion
Smitha any confusion ask me I think I'm
trying third one is showing ranks rank
see suppose 650 rank Hey
okay Neela three to diversify our
methods see we discuss a tattoo type
avoid the confusion we discussed two
types of user-defined methods and I mean
in each method two types of calling two
types of user-defined methods with
returning value without returning value
and in each method and in each method
two types of calling bernad and in each
method are two types of calling you see
here method means list or methods see we
have two types of user-defined methods
what are the two types calling method
without invoking or me and calling me
and user define what is my unit and what
is my question we have two types of
yours are define our methods what are
the two types of user-defined methods
with returning value because yes with
returning value and without returning
any value and then and in each type we
have two types of calling calling
methods what are the two types by
invoking object routine object without
invoking it enough this is the structure
observe of the simple two types of
user-defined methods with the returning
value without returning value and in
each type two types of calling methods
by invoking object without invoking
object without invoking object how you
call using class name
good not assertive next observe usage of
usage of methods usage of methods
already told here usage internal methods
internal use internal use next external
use internal use and external use Ramon
what is internal use our internal method
defining defining means creating
creating and calling calling methods
defining and calling methods within the
same class within the same class up to
now we did this next external use
externally you see very defining calling
sake calling calling methods methods
from other classes one or more okay none
Ella the usage of methods I will show
see respond quickly yes sir yes
internally use we already discussed the
internal Muse nah up to now we created
and collared methods within the same
class next I will show external use
external use just terminated suppose
class one class one first one just
terminated what is that code just
terminate with the returning value is
there now method with returning value
just terminate this one method with
returning value
just run just a minute one more curly
braces run this is the internal use
internal use next external use external
use suppose I am creating one more class
suppose class to observe Gounod I want
to I want to use multiply method from
Java methods another class another class
how to how to access that one just in
hand we are not discussing inheritance
if we inherit you easily reuse Here I am
NOT discussing inheritance that is
concept without inheritance also we can
we can use methods just a minute I want
to call that method which one this one
okay first create a object create
object.observe of 0 Chanel create object
where in class one what is that class 1
Java methods
suppose X Y Z equal to new Java methods
new Java methods semicolon say for this
method for this method multiply method
Java method otherwise make it class 1 in
order to avoid the confusion suppose
class 1 renamed the compiling unit just
a minute here also class 1 we are in
class 2 but creating object using class
1 why for that multiply method class 1
is the home class say X 4i j dot
multiply suppose 10 25 35 semicolon it
is a returning value now is it returning
value and just a minute actually you can
remove this from returning value suppose
into y equal to
run observe observe Neela dream
executing now yes say observe we are we
are calling the method in second class
- but method created in class one not
hello yes yes sir any confusion no sir
here no inheritance na inheritance not
required why here
here you we are using class one name
home class name so no inheritance yes
sir see this is creating creating a
method in class one creating a method in
class one just a minute
last one next accessing from class - you
can access in class one also class two
in just a minute this is plus two first
one class one
class 1 say this is without rate with
returning value by invoking object next
without invoking object guide me through
daily without in working object with
returning value without without in
working object suppose in class one
static static you were required next in
class to no datatype just a minute
without invoking object data type
required no need to create the object
how to call out object class-name what
is the class name class to not matter
class one method definition available in
class one run showing now just a minute
now you can get more clarity class one
observer observes cannot not guru nod
nitrogen this first example is a example
one with returning value method with
returning value
method with returning value and calling
the method by invoking the object by
invoking object
kokaina this is example one yes next the
example two with returning value taurima
calling the value hardened working
object by without invoking listen
without without invoking object it's a
class 2 also I will copy just a minute
just using class name home class name
home class where method created ok
in this first one first type method with
returning value we covered two flavors
by invoking object and without invoking
object nature example 3 this is example
2 next sir I haven't questions
ah if you are calling the method from
the other classes those things should be
in the same package there same package
yes
ok if it is not in the same package then
eerie heritance concept that we will
discuss in woofs chapter or cases
inheritance concept is there now without
inheriting we are reusing examples are
guarded ok example 3 example 3 same 2
method with returning valina without
returning value without returning value
and calling the method by invoking
object this is example 3 next example
for method without returning value and
calling the method without in working
without in working object
okay my remaining two examples guide me
Chanel third one method without
retaining value and calling method with
by invoking object first class one
method without returning value without
returning value means you need to use
void now suppose I will change the
example in just a minute
I'll change the example observed in this
example know without returning any value
without returning any value but by
invoking object okay
first create object class-name class 1
suppose method XYZ a object object X Y
Zed new class 1 okay
next call what is the method name object
name XYZ net method name student and
marks suppose 700 what is the output
ranky thank you
rank e C this is third flavor just a
minute
third one next last one fourth one or is
this flavor method without retaining
value and calling the method without
invoking object Neela dree faster yes
sir is there a static next calling also
no object
no object only using class name yes
class one yes run showing rank inna okay
now all flavor says Smitha
it's her for method one just omit class
one I copied it for this one also class
one next plus two
for our example I didn't copy class -
just a minute just a minute class one
open and closed parent a semicolon just
X Y Z dot student rank of six seven th
or is a problem
a run okay say I forgot this in third
one plus one okay plus two okay now I'll
play versus meta and two more concepts
also there in the CIO's are different
methods but it is not time to discuss
those methods we will discuss those
those examples two more topics are there
two more topics are there we will
discuss those topics in polymorphism
chapter whoops
Java whoops chapter say other topics one
is method overloading method overloading
method overloading
next method overriding say method
overloading method overriding say it is
not time to discuss these two topics we
will discuss these two topics in a
polymorphism chapter polymorphism
chapter okay by method overloading and
method overriding we can achieve
polymorphism okay this is about
user-defined methods again we will use
user-defined method
sin testing chapters selenium-webdriver
in a quarries any queries Artie I am
going to close the session any quarries
nos or thank you for us welcome we're
not not Rajan any queries thank you
Smita
Smita nope no queries okay okay Chanel I
am going to close the session Sunil and
Neal are three any queries good sir
thank you welcome and welcome
