http://uploads.offtopic.com/files/java.zip i don't know what to do? i'm using jcreator but i don't know some things like the averages, and printing each student

What is it you don't understand exactly? How to come up with the average? Think about how you'd come up with an average by hand - add all the numbers together, then divide by the count. You do exactly the same thing in java, have a loop to add them together, then divide the total by the count.

Which would be against the rules of the forum. The assignment in that .zip file was due the day after he posted it anyway, so I don't think he's still looking for an answer.
