Server returned HTTP response code: 500 for URL

si trasformerebbe così:

    /**
     *
     */
    private static final long serialVersionUID = 1L;

    /**
     * Extends the size of an array.
     */
    public void sendPostRequest() {

        //Build parameter string
        //String data = "/id_sra=2/id_file=1";
        try {

            // Send the request
            URL url = new URL("https://ip?nome=pippo&cognome=pluto);
            HttpsURLConnection conn = ( HttpsURLConnection ) url.openConnection () ;

            conn.setRequestMethod("GET");
            conn.setDoOutput(true);
            conn.setDoInput(true);
            conn.setUseCaches(false);
            conn.setAllowUserInteraction(false);

            conn.setHostnameVerifier ( new NullHostnameVerifier ()) ;
            conn.setRequestProperty("Content-Type", "text/plain");



            //write parameters
           //** writer.write(data);
            //** writer.flush();

            // Get the response
            StringBuffer answer = new StringBuffer();
            BufferedReader reader = new BufferedReader(new InputStreamReader(conn.getInputStream()));
            String line;
            while ((line = reader.readLine()) != null) {
                answer.append(line);
            }

            reader.close();

            //Output the response
            System.out.println(answer.toString());

        } catch (MalformedURLException ex) {
            ex.printStackTrace();
        } catch (IOException ex) {
            ex.printStackTrace();
        }
    }
    /**
     * Starts the program
     *
     * @param args the command line arguments
     */
    public static void main(String[] args) {
        new Main().sendPostRequest();
    }

    private static class NullHostnameVerifier implements HostnameVerifier {
        public boolean verify ( String hostname, SSLSession session ) {
            return true ;
        }
   }
} 

però mi da lo stesso errore
