Any problem in any area of the Java section of codingbat.com makes for
good practice.  Here are some I have recently inspected/completed that
I think make for particularly good practice.

The point of these exercises is to solve them independently to help
you practice for the exam.  You may of course seek guidance from the
instructor, the tutors, each other, etc. but ensure you are thinking
though the solutions.  It's pretty pointless to just see the solution
code... reading code is not the point of the final exam.  Creating
code is the point.
