Method in Java
Use of methods in Java
Main method in Java
return type in methods
Syntax of method
#1
A method in Java or Java Method is a collection of statements that perform some specific task and return the result to the caller.
Methods in Java allow us to reuse the code without retyping code.
In Java, we create the components with the help of classes.
Every class has a behavior and it is defined through the method.
Behaviour or method is defined with the round brackets ().
For every method, we also have to specify the type of access to it.
Method does some tasks and it also returns something.
We can call methods by creating an object.
We can pass also pass values in a method.
We can also put conditions inside the method like with the help of if..else.
return keyword stops the execution of a method as it does not execute the further statements after it.
#2
-- void is used when we do not want a method to return something.
-- String is used to return a string value.
-- int is used to return an integer value.
Main method is the start of execution from where the program begins.
#3
The syntax for method:-
class Computer
{
public void playMusic()
{
System.out.println("Music Playing..");
}
}

[@abhishekmitra9712]

Watching this video today and realized that your joke about "Nothing phone" actually became true. There is actually something called nothing phone.😄

[@smittt20]

The kind of details in the video like explaining every single word from void to object to function helped me a lot, i have never understood class and object effectively until now. Thanks a lot sir

[@Sorjen108]

[@everyone3602]

dr's of java

[@czarscrib3680]

I knew about the nothing phone but I wasn't expecting that joke😅😅😅😅

[@JehanSaren]

Hi Sir, please help🙏, how to access the variables inside the method to another method? Void Room1(){ name1="Elisa"; name2="Jefrey"; } Void Room2(){ i want to access "Elisa" }

[@droste07]

Then you have to create instance variable (variable inside the class) then you can access it anywhere in the class block!

[@DarkyBoy-n1i]

Sir, Who returns nothing?🤣🤣🤣🤣

[@pratiktiwariramji]

[@rkrk5378]

One SUGESSTION Sir, Please don't give different 2 examples, Please stick to one example through out the video.. if you are giving example of 'Computer' then please stick to that example only Instead of giving several examples like Car, Pen, Computer etc this could confuse a viewer.. OTHERWISE THE VIDEO WAS GOOD

[@singasong7679]

method inside method give error. please correct this anyone ij() in k() method show error class A{ int i; int j; void ij(){ System.out.println("i and j"+i+ " "+j); } int show(){ return i+j; } class B extends A{ int k; void k(){ System.out.println("value of k"+k); ij(); } int sumijk(){ return show()+k; } public static void main(String[] args) { B obj =new B(); obj.i=44; obj.j=33; obj.k=21; int c=obj.sumijk(); System.out.println("value of sum"+c); } } }
