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.
Please use ctrl-C ctrl-V to copy your code, so as to avoid spelling errors like
You ought not to use the == operator to check objects (which includes Strings); try
instead. And make sure that you are using exactly the correct spelling for ALL. Have you really declared "double d" in the if? In that case the code won't compile in the first place. PostRealCode, please.
