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 am SCJP certified (1.4) but is expiring soon. I used your book earlier and planning to get re-certied. The question is: Can I use the earlier book, is it still good enough or has there any updates/new material ?
