Thread: Java won't compile

I know nothing of Java, however, I've got a class that demands it, and I'm stuck.

I got this code by using Visual Paradigm to convert this from UML to code. I changed what I could based on what we've learned in class, but it won't compile. It is supposed to compile but not execute. Any feedback is greatly appreciated.

I think next week we move on to XML, thank goodness.

OK. Here's the code. I'll put the errors in another post.
