Methods are similar to functions and expose the behavior of objects. Example: Java program to demonstrate how to create and use a method.

Methods are used to perform certain actions, and they are also known as functions. Why use methods? To reuse code: define the code once, and use it many times. A method must be declared within a class. It is defined with the name of the method, followed by parentheses ().
