The Java Extra Credit problem set is the actual first problem set for a
second-semester CS class (i.e., the class you would take right after this
one). Completing it gives you significant extra credit in this class, as
well as the knowledge that you are well-prepared for a subsequent CS class.
Materials:
Read the problem set description. Although it seems long and involved,
there are actually only three questions (on pages 5 and 6) and only two of
them are required.
You will need to research Java on your own (e.g., Google "java tutorial").
That's it! Good luck!
