how do i print a variable inside a servlet

Question

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"));

    out.print(+id+);
}

/**
 * Returns a short description of the servlet.

Answer 1

You can use ServletOutputStream with print() method. Another possibility is to use PrintWriter .

response.getWriter().print(variableToPrint);

Answer 2

Usually, you can do something like that,

String json = "<some_JSON>";

response.setContentType("application/json");
response.setCharacterEncoding("UTF-8");
response.getWriter().write(json);

, and you will see your response printed in the log console.

In the same way, you can write your value instead of a JSON.
