New to Java

Good Day:

I'm totally new and performing a very simple test. With the code on below, when I compile and run using dos prompt, no problem - is showed the "Testing" message.

But if I copy and paste it to netbeans 5.5, it doesn't have any output. I think something got to be added on to the code if I were to see the result? pls help!

Thanks!

public class Testing{
public static void main(String[] args)
{
System.out.println("Testing");

}
}
