Java Homework Help?

spatel14

Hey guys, I'm taking my first Java programming class right now and I was wondering if I could get some help with my first assignment. The .pdf to the file is here:

Now, the first two classes were easy to implement and I got them working just fine, but the last class is proving to be difficult. I can't figure out what predegrees and postdegrees are.. Can anyone explain this to me, or is there a better way to implement a pie chart other than what is explained in the homework?

Thanks guys.
