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.
EDIT: I am very sorry for a misleading post. The above line of code compiles. But, throws an exception - java.util.regex.PatternSyntaxException: Unexpected internal error near index 1.
Thanks Bear Bibeault.
