Answer / sonia

GenericServlet belongs to javax.servlet package
GenericServlet is an abstract class which extends Object and
implements Servlet, ServletConfig and java.io.Serializable
interfaces.
The direct subclass to GenericServlet is HttpServlet.It is a
protocol-independent servlet.
To write a GenericServlet you need abstract service() to be
overridden.


HttpServlet:
HttpServlet belongs to javax.servlet.http package
This is an abstract class which extends GenericServlet and
implements java.io.Serializable
A subclass of HttpServlet must override at least one method
of doGet(), doPost(),doPut(), doDelete(), init(), destroy(),
getServletInfo()

Answer / sudha rani

A GenericServlet has a service() method aimed to handle
requests. HttpServlet extends GenericServlet and adds
support for doGet(), doPost(), doHead() methods (HTTP 1.0)
plus doPut(), doOptions(), doDelete(), doTrace() methods
(HTTP 1.1).
Both these classes are abstract.
