Catch an HTTP Error

Question

Hello all,
Can you tell me if there's any way to get an HTTP 500 Error with the code below:
    html = "";
    int r;
    BufferedInputStream in=null;
    do {
      retry = false;
      try {
     in = new BufferedInputStream(url.openStream(), 4096);
     //      System.out.println("DoneOpening input stream");
      catch (IOException ioe) {
     ioe.printStackTrace();
      try {
       //       while(in.available() == 0){
       // System.out.println("Nothing available on input stream!");
       while ((r = in.read(buffer, 0, buffer.length))!=-1) {
           if (r>0) {
            html = html + new String(buffer, 0, r);
           //           System.out.print(".");
      catch (IOException ioe) {
      }With this code I can get the HTML code but my objective here is to get the HTTP Header and catch an HTTP Status (Error) message (e.g. HTTP 500 ). Is it possible?
Best regards,
Nuno

change the code piece
in = new BufferedInputStream(url.openStream(), 4096);with this one
HttpURLConnection connection = (HttpURLConnection) url.openConnection();
int responseCode = connection.getResponseCode();
if (responseCode == HttpURLConnection.HTTP_INTERNAL_ERROR) { // error code 500
     // do your stuff here
in = new BufferedInputStream(connection.getInputStream(), 4096);
