I would start with:

private class askTheTeacherWhatToDo implements bullShit {}

You may need to study some of the basics of DAOs ...

http://java.sun.com/blueprints/corej2eepatterns/Patterns/DataAccessObject.html

http://www.corej2eepatterns.com/Patterns2ndEd/DataAccessObject.htm

The best introduction to the general topic of core J2EE design patterns
is Core J2EE Patterns: Best Practices and Design Strategies by Dan
Malks, Deepak Alur, and John Crupi.

If you're really not so sure about what you're doing, you could try
generating the DAOs rather than hand coding. You can read more about
that here:
