I'm glad you all enjoyed it, and thanks PAWS for giving that link in jcreator. I thought I had it in the first tutorial but I think it is actually in the one I wrote about applets. To use jcreator you will also need to download the java sdk
from http://java.sun.com
make sure to install the sdk first, then jcreator because jcreator needs the sdk to compile and run the programs.
