What happens if I declare HttpServletRequest as final & HttpServletResponse as final in a doPost method. I am trying to test that in a login page.

do you have an understanding of the `final` keyword? That means you will not be able to reassign the object after initialization. That's what happens when you add final to those types. – ddavison Feb 13 '14 at 16:04

so there will be no difference in using request1 & request2, if I declare `final HttpServletRequest request1` or `HttpServletRequest request2` – Anjigadu Feb 13 '14 at 16:08

@Anjigadu that's what I'm saying in my answer. – Luiggi Mendoza Feb 13 '14 at 16:08

It won't affect your application, you just can not modify their references in the doPost method, but even if you could (by not marking them as final) you should not even attempt to do it. It would be a very bad idea to modify these references. Still, even by declaring them as final you can modify their state e.g. adding and removing attributes in request.
There's a good explanation about final parameters here: final keyword in method parameters
