I am doing a slot machine project. It is close to completion and as far as I know runs perfectly, as I took great care in checking for and eliminating bugs (one thing that may arguably be a bit sloppy is the fact it is possible to get a 3 in a row of more than one type of value). However, there are a few requirements I have yet to complete, and these requirements merely are to demonstrate that I know material from previous chapters.
Requirements I would appreciate help with said:
5. At least ONE interface and THREE classes (One of which MUST be abstract), Not including the driver, which brings the total to FIVE.
9. Polymorphism must be implemented with the student designed classes.
10. Class Array List must be used in at least ONE student designed class and it MUST be traversed through AND accessed via an Iterator.
12. Animation OR Graphical Interface are optional for extra points

However, I would also appreciate help understanding how to do graphics. I guess I have one simple fundamental question about Java and graphics. Like, say you have some images saved on your computer that you want to apply (probably as slot icons I'd assume). How do you apply those images onto like a Java applet? On a related note, I believe this is why I can't get this code (not related to the project) to work. Tiled Pictures Java, aka there are supposed to be pictures that are displayed getting progressively smaller from the lower right to the upper left.
Now, I'll show what code I'm using.
