public static void main(String[] args) {
        String url = "http://localhost/DTKCPTSWJ/NewsDetail.aspx?PID=9&ClassID=19&NewsID=115";
        String[] parameters = { "ClassID", "NewsID" };
        String u;
        try {
            u = URLDecoder.decode(url, "UTF-8");
            for (String s : parameters) {
                String[] a = new String[2];
                if (u.indexOf(s) != -1) {
                    a = (u.substring(u.indexOf(s))).split("&");
                    a[0].split("=");
                }
                System.out.println(a[0]);
            }
        } catch (UnsupportedEncodingException e) {
            e.printStackTrace();
