i am having this problem where i have retrieved a value using the post method and i want to print that value how do i do that?

@Override
protected void doPost(HttpServletRequest request, HttpServletResponse response)
        throws ServletException, IOException {

    String comment = request.getParameter("comment");
    PrintWriter out = response.getWriter();
    int id = Integer.parseInt(request.getParameter("qid"));
