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..");
}
}
