Thanks again for your help, now all I have to do is write the program. *dies*
I think my main trouble was that the computers at Uni use Linux, and that confused the hell out of me, but I have used some of those commands you mentioned before, just not in windows.

p.s. Depending on how you set up your classpaths, if the command prompt says that it doesn't recognize the "javac" command, you might have to implicitly say where the "javac" command lives. That's why most people set up their classpaths so that they can call the "java" and "javac" commands from anywhere.
Yeah I think I did that. There was installation instructions the lecturer typed which included something about adding lines to an autoexec.bak file so you could run the commands from anywhere though I don't know if it worked or not.
