Simple Methods

Methods allow the programmer to create pieces of reusable code.

Syntax:

public int add(int x, int y)
{
return (x+y);
}

In the above header there are a few important details:
Public defines whether the method can be used by a program outside of the current class (more on this later).

int defines what the return type is from the method.

add is the method's name (this can be anything).

(int x, int y) are the parameters of the method. This method has two parameters x and y, and both are of type integer.

return sends a value back to the method that call add.

Calling a method is a term used when a program uses a method. For example if we were using exp in main it would look like this.

public static void main()
{
int a=5, b=7;
int sum=0;
sum = add(a,b);
Sytem.out.println(sum);
}

What should the output be?
