* GenericServlet defines a generic, protocol-independent servlet.
* GenericServlet gives a blueprint and makes writing servlet easier.
* GenericServlet provides simple versions of the lifecycle methods init and destroy and of the methods in the ServletConfig interface.
* GenericServlet implements the log method, declared in the ServletContext interface.

GenericServlet is an abstract class which is protocol independent mean we can use GenericServlet to handle HTTP requests,ftp requestes etc.. HttpServlet is protocol specific it is intended to handle HTTPRequests only.
