How do I set the maximum age of a cookie?

package org.kodejava.example.servlet;

import java.io.IOException;
import javax.servlet.ServletException;
import javax.servlet.http.Cookie;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

public class CookieExpirationExample extends HttpServlet {

    protected void doGet(HttpServletRequest request,
	    HttpServletResponse response) throws ServletException, IOException {
	doPost(request, response);
    }

    protected void doPost(HttpServletRequest request,
	    HttpServletResponse response) throws ServletException, IOException {
	String username = request.getParameter("username");
	if (username != null) {
	    Cookie cookie = new Cookie("username", username);
	    
	    //
	    // Set the cookie age to 600 seconds (10 minutes). Setting the age
	    // to 0 will delete the cookie while giving it a negative value will
	    // not store the cookie and it will be deleted when the browser is
	    // closed.
	    //
	    cookie.setMaxAge(600);
	    response.addCookie(cookie);
	}
    }
}
