Thanks, both of you, for the advice on using classes. I'm currently reading through a book titled "Java Programming: From the Ground Up", and have just gotten to the basics of OOP. In fact, I think the chapter I'm about to start is about making classes and implementing them correctly.
Btw. for method lengths a good rule of thumb is methods between 3 and 7 lines, especially when the logic is complex, you want less lines.
I'm always afraid that I'm going to have too many methods in my program, so would I clear this up by making custom classes, and then just creating an object that can reference them?
Code Complete seems to be a seminal book that might interest you, although I haven't read it myself so I can't vouch for it.
Thanks for this! I'll look it up on Amazon and give it a whirl.
