In this tutorial we will be creating our first application, the standard “Hello World” used as the first lesson in most programming languages.

To make it a little more interesting I have broken the lesson into two parts. In the first part I will demonstrate how to make the “Hello World” application with just notepad and the JDK command line.  In the second we will use the Eclipse IDE to accomplish the same application.

The code for both sets (just in case it’s not clear in the video) is:

public class HelloWorld
{
public static void main(String[] args)
{
System.out.println(“Hello World”);
}
}

The command line is accessed by in Windows 7 by clicking the windows button, type ‘run’ in search box, them type ‘cmd’ and press enter.  Also, Windows 7 will not allow you to save the HelloWorld to the root of C:\ so you will need to put it in another folder like C:\java.
The easiest way to do this in Windows 7 is:

cd \Program Files (x86)\Java\jdk1.6.0_20\bin (your jdk directory might be different)
then at the Prompt type: javac  c:\java\HelloWorld.java
