Because it implements many methods of this class, if it was an interface you would be forced to implement every single method in it, which is not exactly what you want (unless you have a lot of time to waste). if you look at this class API you find many implemented methods

Thank you...I really overloked those methods. I had only the abstract method in my mind.

Thanks again....

You are welcome Kousik, remember that Object Oriented & Design patterns are very important, try to follow them as much as possible to write clean and great code.
