          Please google or search the forum. This question is asked very very often.

              @OP. Please do also use a better subject next time. We know that you are posting here because you want to know about java programming, so that doesn't help much.

                what is the difference between 'abstract' class and
                'interface'
                An abstract class can have some concrete methods (from none to all)whereas an interface always only have abstract methods.

                This question is asked frequently but it never seems the OP ever understands the reply. So I'm curious as to how long you have been programming and what prompted you to ask this?

                  There's something strange with this question. It doesn't matter what you reply, the OP never comes back for additional information or to say thank you I got it. So I figure the most succinct and informative reply probably is:

                  I have a doubt. Why do you ask?

                  Am I getting cynical. You bet I am. I better stop posting for a while otherwise I may join the Annual Newbie Hunt this year. -:)

                    It's about 99% chance that a new user never posts again, especially if you say that the question has been asked many times before.

                      Well I guess I haven't qualified myself for this year's hunt. Maybe I could get a free-card because I was always on the Most Arrogant List a few years ago.

                        Ok. I'll be nice. You'll get a free pass.
