Creating A Java Project:

The first step you need to do is to create a Java Project. This is very easy. All you need to do is click 'File' in the upper right hand corner, click on 'New' and the first thing you will see is, 'Java Project'. Click that and then call it whatever you want, I called mine, Test.

Creating Classes Inside Your Project:

You will have two types of classes in side your project, a main class and sub-classes. Right now, you just need to focus on your main class. To create a class for your project, just right click the project, click on 'New' and then click on Class as shown in the picture below.


Once again, you can call it whatever you want.

Hello World:

Now it's finally time to create your first Java Application! Like I said before, you will need a main class. To make the class you just create the main one, follow these instructions:

class test {
public static void main(String args[]) { (This is the line that shows which class is the main method)
System.out.println("Hello World"); (This is what the console reads and shows)

Now just click, 'Run' in the upper left hand corner and in the bottom of Eclipse you will see, Hello World.

You did it! You just created your first Java Application. Now this is where it gets trickier and more fun so stay tuned for more tutorials later on! Thanks for reading.
