Hello World

A "hello world" program is usually the simplest program that actually does anything. For comparison with Java, here it is in BASIC:

10 print"Hello World"

And in JavaScript:

document.write("hello world")

Compared to those ever-so-complicated languages, writing one in Java is *so* easy:

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

}
