Try reading some of these (I did a search on Interface and abstract to get some references): http://www.javaranch.com/ubb/Forum33/HTML/002345.html http://www.javaranch.com/ubb/Forum33/HTML/002318.html http://www.javaranch.com/ubb/Forum33/HTML/002016.html
etc

and kesava,
The Java Ranch has thousands of visitors every week, many with surprisingly similar names. To avoid confusion we have a naming convention, described at "JavaRanch Naming Policy" . We require names to have at least two words (not just letters), separated by a space, and strongly recommend that you use your full real name. We want to get to know you as a Professional. Please choose a new name which meets the requirements and re-register.
Cindy
