Well, when you build it in Netbeans it creates a Jar file. Jar files are universal in Java, its basicly an executable zip file. But the mime-type need to be correctly set to run it. If not go to DOS or a terminal, and then run "java -jar helloworld.jar". The jar file is located in the Netbeans Project Folders. Example is "My Documents/Netbean Projects/helloworld/dist" or it might be "build" folder.

Thanks, Eclipse has this as well but it seems a bit more clunky and slower

He's using Windows 98 (hence, it can be assumed its a slow machine) unlike you computer freak :P working on a Dual or Quad core processor ;)

For beginners,it is highly recommended to avoid the use of an IDE, as you will fail to unerstand the basic workings of java as much is done for you. Furthermore you will not be able to learn from your mistakes, as the IDE will simply suggest a correction rather than get you to work out the issue. What annoyed me here is that you said "ignore all that package and stuff" (or something to that effect) , really this is not good Java teaching, things like this are core to Java

Notepad ++ usually works good on every thing
