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.
This site is to help you with your code and other related issues, not to give you THE code.
Search the same thing on google and write something on your own, if you face any trouble then post your code and we will help you out.
