What about HttpServlet class? This class doesn't have any abstract method, still is an abstract class.

According to my knowledge, Generic Servlet class implements Servlet interface and it gives definition of all the methods present in Servlet interface except service() method. service() method is abstract in Generic Servlet class, that's why Generic Servlet is an abstract class.Please correct me if I am wrong or is there anything I can add in my explanation.
