GenericServlet is a class in javax.servlet package which implements the Servlet interface.This class is independant of the protocol.
HttpServlet is a class in javax.servlet.Http package which extends the GenericServlet class.All Http servlets must extend the HttpServlet class.

if we use Genric then the service() is required to be overridden but in case of Http Servlet it is already there and no need to override.
