    void makeQuery(String query) {
   
     System.out.println(" Querying for " + query);
   
     try
     {
      // Convert spaces to +, etc. to make a valid URL
      query = URLEncoder.encode(query, "UTF-8");
     // note: you can change the start index here.
      URL url = new URL("http://ajax.googleapis.com/ajax/services/search/web?start=0&rsz=large&v=1.0&q=" + query);
        println("hello before");
   
      URLConnection connection = url.openConnection();
       connection.addRequestProperty("Referer", HTTP_REFERER);
     
      // Get the JSON response
      String line;
      StringBuilder builder = new StringBuilder();
    //      println("hello");
      BufferedReader reader = new BufferedReader(new InputStreamReader(connection.getInputStream()));
      while((line = reader.readLine()) != null) {
       builder.append(line);
      }
    
      String response = builder.toString();
      JSONObject json = new JSONObject(response);
   
      System.out.println("Total results = " +
        json.getJSONObject("responseData").getJSONObject("cursor").getString("estimatedResultCount"));
   
      JSONArray ja = json.getJSONObject("responseData").getJSONArray("results");
   
      System.out.println(" Results:");
      for (int i = 0; i < ja.length(); i++) {
       System.out.print((i+1) + ". ");
       JSONObject j = ja.getJSONObject(i);
       System.out.println(j.getString("titleNoFormatting"));
       System.out.println(j.getString("url"));
      }
     }
     catch (Exception e) {
      System.err.println("Something went wrong...");
      e.printStackTrace();
     }

Can anyone please help me out how can I resolve this exception?

Thanks.
