hm, I'll try that. I need more practice navigating with cmd anyway. I doubt I'll deal with Swing much right away if I'm doing that, but I can still import the swing libraries as usual if I wanted to, right?

That was actually the exact answer I was trying to get. Thanks! So upon compiling those two .java files, I'd tell Netbeans (for example) to compile as I would anything else since it puts them in the same package when I make them. right?

Oh also, assuming I make a class to handle the calculations, I can call methods from it in other objects, right? It doesn't have to be the one with the main?

i.e. in the event handling class, I can tell it to, instead of printing out a line, to look to say...calc.java to call calc.add? Or do I have to call new calc() first?

I would just fiddle and test all this myself, but I'm at work right now and I don't think these computers have the SDK.

Okay, so I'm comfortable with Visual Basic's program setup. (A main form + a bunch of modules to hold your functions.) What I didn't understand in the tutorial on the Sun website was how the pieces fit together. Say I wanted to make a basic calculator program with a swing UI. Would I have a bunch of .java files for each object/class I make? Where would I call these methods, tell the program to run some on startup or event handling code? As of now I can write some decent object code but I have NO clue how to make them work together. Thanks for any help.
