The diff is that inGeneracicServlet we had to implement the
service()method the GenericServlets service() method is
declared as abstract.But the Generic Servlet is not
implementing keeping the HttpSErvers in mind. Methods we
have in this class are
init()
log()
service()
While implementing the HTTP Servlet the service() method is
already implemented .service()method of HTTP sevlet is
declared as protected.the HTTPServlet is implementing
keeping the HttpSErvers in mind. Methods we have in this
class are
doGet(),doDelete(),doPost()

Answer / l sujata
Actually generic sevlet class is a super class of
HttpServlet class.both of these classes are abstract in
nature.As in generic servlet service () methob is not
defined so they r defined in HttpServlet class. as we are
not interested to create an object of HttpServlet class
so,we make it as abstract class and class that implemnts
HttpServlet Class creates objects and uses three methods
such as init(),service(),destroy() mainly.

Answer / qim2010
Both these classes are abstract but the differences are
A GenericServlet has a service() method to handle
requests.
The HttpServlet extends GenericServlet and adds support
for HTTP
protocol based methods like doGet(), doPost(), doHead()
etc. All
client requests are handled through the service() method.
The service method dispatches the request to an appropriate
method like doGet(), doPost() etc to handle that request.
HttpServlet also has methods like doHead(), doPut(),
doOptions(),
doDelete(), and doTrace().
GenericServlet is Protocol independent. GenericServlet is
for servlets
that might not use HTTP (for example FTP service).
But HttpServlet is protocol dependent (i.e. HTTP).

Answer / luqman khan
HttpServlet is used to handle only http request & response.
where as GenericServlet is used to handle any type of requests.
Http servlet sends large data and its protocol ndependent
whereas GenericServlet sends a small data
Http servlet support cookies sessions.whereas genericservlet
does not support sessions.
Http servlet is protocol dependent.
it is a sub class of GenericServlet.
HttpServlet is a Abstract class.
