6 - Methods

While you are programming, there may be parts of your code which you will want to re-use rather than re-writing them.  That is where methods come in.  Methods  allow you to create blocks of code which have some functionality which can easily be used.  In this tutorial I will teach you what makes up a method, and how to use them in your code.

Note:  You may be wondering why methods are called methods instead of functions.  Methods are essentially the OOP version of functions.  There are a few slight differences between them, but for the most part they are the same.

Anatomy of a Method

<Type> <Name> (<Parameters>) { //do stuff code }

Name

Each method that you create will have a unique name assigned to it.

Parameters

Very often, you will want to pass in variables to a method you create.  Parameters are the variables that you put into the parameter section of your method.

Return

Sometimes you will want to return some value when you call a method.  Return types and the return keyword are how you will achieve this.
