My out put is OK for the Project & Contestant Name, but the Average Score is not calculating correctly. it keeps returning 4.

Write some getters for Project1 .. Project n
Print out the values before you call the average. It will make sense as to why you are getting 4 every time.

Step through your code and follow the path it takes.

Also, the formatting was lost on your first class, or it was done incorrectly, makes it terribly hard to read.
