Haraprasad, as a beginning programmer, it is understandable that you would be confused. However, you have to man up and learn to help yourself. Google is just a click away and it's actually easier to type "Java boolean operations" into Google search than it is to type "Please give me the reference (any books, blah blah blah" and post a message that, frankly, annoys the people here who have already given you a lot of tips. We try to be friendly and patient here but showing some effort instead of asking to be spoon fed also goes a long way in gaining respect and empathy.
