#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..”);
}
}
