In response to #2, your comments made me look back at the assignment and I now notice that it only calls for me to put in the hours for the week, not for each day. Thanks. In response to #5, I have to stick with the UML diagram that was provided in the class and cannot add any additional methods to the classes.

Thanks very much for all the suggestions. I have implemented most of what you indicated.

Thanks for your feedback. Very helpful. id = Integer.valueOf(initialId); was a leftover that from earlier work that I forgot to simplify. The overuse of comments is because the instructor for the courst that I am taking indicates that he would like everything commented. As for creating a separate IdGenerator, I am not allowed to as it is not part of the spec.
