This week's book giveaway is in the OCPJP forum. We're giving away four copies of OCA/OCP Java SE 7 Programmer I & II Study Guide and have Kathy Sierra & Bert Bates on-line! See this thread for details.
I'm closing this thread because it doesn't really ask a question. Many people will be working on an assignment at any given time. I did this assignment in the past. If you have a question about the assignment, ask it in a new thread.
