Hi, Thanks all of you for motivating me, some way or the other. I am proud to say that I am a big fan of the HEAD FIRST series and its authors Kathy Sierra and Bert Bates. I recommend their books to all of my friends. I used two books viz. 1.Khalid Mughal and 2. Kathy Sierra and Bert Bates. Both the books complement each other. But the questions I encountered were very similar to that of K&B. Thanks once again to the members of this largest online developer community!!! Regards, Ram.
