Write a SERVLET program which counts how many times a user has visited a web page. If user is visiting the page for the first time, display a welcome message. If the user is revisiting the page, display the number of times visited. (Use Cookie)

import javax.servlet.http.*;
public class VisitServlet extends HttpServlet
{
    static int i=1;
    public void doGet(HttpServletRequest request, HttpServletResponse response)
        throws IOException, ServletException
    {
        response.setContentType("text/html");
        PrintWriter out = response.getWriter();
        String k=String.valueOf(i);
        Cookie c = new Cookie("visit",k);
        response.addCookie(c);
        int j=Integer.parseInt(c.getValue());
        if(j==1)
        {
            out.println("Welcome");
        }
        else
        {
            out.println("You visited "+i+" times");
        }
                i++;
