How to reuse Request.getParameter(“paramName”) in other place in doGet servlet

Question

I have doGet and doPost methods in a servlet and I have Request.getParameter("paramName") in both of them I want to use Request.getParameter("paramName") out of doGet in another place in my code for example:

protected void doGet(HttpServletRequest Request, HttpServletResponse res) throws IOException {
        res.setContentType("text/html");
        PrintWriter pw = res.getWriter();        
        pw.print("Param is "+  Request.getParameter("paramName"));
    }

  PrintWriter out = res.getWriter();
  out.write( Request.getParameter("paramName"));

Could it be possible to achieve this?

Answer 1

You can either pass request to the method, or pull the value into a variable and pass that to the method.

String data = Request.getParameter("paramName");
doSomethingWithData(data);

private void doSomethingWithData(String data){
    System.out.println(data);
}
