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, callHttpServletRequest.getParameterMap()and iterate over the keys in the returned map.
