Would you like to restrict your question to something less that the size of an entire chapter in a Textbook.
Also, please re-register without the underscore in your name. Your name should be compliant with JavaRanch's naming policy. Your ID should be 2 separate names with more than 1 letter each. Thanks, Cindy

sohrab_niazi, Any good java text will answer these questions. If you don't have one, there are a number of free ones online. Check out Thinking in Java by Bruce Eckel, also check Sun's site for the Java Tutorial, or even the Java Language Specification.
