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.
K&B is simple to understand but it should be used as a first timer because book is exam specific and skips lots of concept(but clkarifies a hell lot more) and writers themselves suggest that the book should be used with some previous java knowledge , if you do coding that would count,
but for exam perspective it is best book available, and more informative than any other java source I found
