Tutorial: Methods - Introduction

The word method is commonly used in Object-Oriented Programming and is used in Java.

Tutorial Details:

Method = Function = Procedure = Subroutine = Subprogram
The word method is commonly used in Object-Oriented Programming and is used in Java. Every programmer has this idea, but sometimes uses other terms such as function, procedure, subroutine, ... Many programmers use these other terms, especially function, but these notes will use method.

Why use methods?
For reusable code
If you need to do the same thing, or almost the same thing, many times, write a method to do it, then call the method each time you have to do that task.
To parameterize code
In addition to making reusable code that is the same in all cases, you will often want to use parameters that change the way the method works.
