Is there a better way to check for null in HttpServletRequest.getParamter()

Question

Can there a better/optimized way to extract value from request ?

void m() {
    String tFlag = request.getParameter("tFlag");

    tFlag = (tFlag == null) ? "" : tFlag;
}

Answer 1

If you could use Java-8, you can use Optional.ofNullable as :

String tFlag = Optional.ofNullable(request.getParameter("tFlag")).orElse("");

or alternatively the suggestion from ernest_k in comments :

String tFlag = request.getParameterMap().getOrDefault("tFlag", "")
