Efficient way of identifying request parameter

There are 11 request parameters coming from client side to a servlet. Once a request comes any one of them is set. I need to identify which parameter is set. Is there an efficient way to identify the parameter set in client side?

The cost calling HttpServletRequest.getParameter(String) on 11 possible parameters will be barely noticeable. If it worries you though, call HttpServletRequest.getParameterMap() and iterate over the keys in the returned map.
