I am at present working on servlets, I am encountered an difficulty in differentiating b/w getAttribute and getParameter in servlets

I basicallly know
request.getAttribute("String") returns value in string

request.getParameter("String") returns an Object :roll:
I did not understand what type of object it returns

Thanks in advance

You've got it backwards.

GetParameter returns a String. It's what you use to retrieve form parameters from an HTTP post.

getAttribute(String) and setAttribute(String, Object) are what you use to bind object variables to a scope (request, session, or context) and retrieve them from another servlet or JSP.
