To find number of parameter from request

Question

Freinds,
Is there any way to find out number of parameter submitted from request object. But the constraint will be with out going through loop.
Example
int count = 0;
          Enumeration list = request.getParameterNames();
          while (list.hasMoreElements())     {
               count++;
               list.nextElement();
          }
