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.
In kathy and bert certification book it is mentioned there is 49 keywords and identifiers. I was going through Complet Java 2 Certification - Philip Heller and Simon Roberts book it says 52 keywords including "false, null and true" which is right!... Thank you for the reply.
