I moved your code around. I think it now does what you wanted.
It actually needs some changes to be good OOP, but I wanted it to still be reconizable to you.

import java.util.*;
public class...

Personally, I like Eclipse. Certainly better than NetBeans. These guys are right though, you don't really need 2 learning curves at once.

As a first tool, I'd recommend TextPad. It's mostly...

try
{
Thread.sleep(1000); // do nothing for 1000 miliseconds (1 second)
}
catch(InterruptedException e)
{
e.printStackTrace();
}
