Some Help Please

That's a very large list of things. If you have a textbook for the class, I'd suggest reading through it, or you can look at Java Classes and Objects Lesson.

If you have any specific questions, ask us. Oh, and by reading through the requirements for your program, I don't think it's a set that you want, but rather an array. If your teacher will allow it, use an ArrayList. They are basically arrays, but they have extra code that makes expanding them very easy. You can read about Java Arrays here if your teacher won't let you use ArrayLists.

What do you have?

I'm sorry alonino but there is no way we are going to complete all of this for you. You obviously haven't left enough time to finish this work. To get help you need to show us the steps you have taken to complete this work yourself. At least show us your basic classes so we can help you move forward.

If you are really desperate, I suggest you post in the 'paid projects' forum and hire someone to do this work for you.

A quick search of the forums brought up this code. It may help you get started..
