  1. Many Methods & Instances

    by , January 29th, 2012 at 15:52 (JD1's Personal Development Blog)
    This post goes over how we can use multiple methods in different classes. It's a very inefficient program we've written, but it's designed to show you exactly what each method does and how they relate to each other. Here's Class2, the guts of the application. I've included comments to show you what everything does.

    public class Class2 {
    	//New string
    	private String friendName;
    	/* This method is responsible for collecting the name
    	 * variable

  2. Private Variables

    Private variables cannot be used over multiple classes. They are specific to the class in which they were created, hence the private part. You can declare a private variable by writing private before it, as seen below.

    private String devName;

    If the variable devName was in Class2, it would not be able to be used in Class1, since it is exclusive to its home class, if you will.

  3. Comments

    You can make comments in your Java code in two ways, single line comments, and multiple line comments. Below is a single line comment.

    //This is a single line comment.

    And below is a multiple line comment.

    /*This is a multiple line comment.
    It can span over multiple lines.*/

    Comments are used to explain certain code to yourself and others that may be reading your code.

  4. I've Learned About A Few General Java/Programming Conventions

    by , January 29th, 2012 at 15:51 (JD1's Personal Development Blog)
    First of all, thanks to the following members for helping me out thus far. I very much appreciate your time and effort and I've decided to take everything on board.




    First of all, KevinWorkman told me of the importance of implementing braces on all statements (If Statements, Switch Statements, etc) regardless of whether there's only one line's code after the condition. If you don't implement braces around these statements ...

    String name="Tony";
    vs
    String name = "Tony";
