I am trying to show the message based on the text shown on webpage after a particular action. If the webpage contains text MESSAGE HAS BEEN SUBMITTED SUCCESSFULLY, I want to print Message sent successfully on the screen otherwise MESSAGE SENDING FAILED. Everything is working fine but for one thing.

PrintWriter printWriter = new PrintWriter(new OutputStreamWriter(sendConnection.getOutputStream()), true);
        printWriter.print(sendContent);
        printWriter.flush();
        printWriter.close();
        //Reading the returned web page to analyse whether the operation was sucessfull

        BufferedReader bufferedReader = new BufferedReader(new InputStreamReader(sendConnection.getInputStream()));

        StringBuilder SendResult = new StringBuilder();
        String line;

        while ((line = bufferedReader.readLine()) != null) {
            SendResult.append(line);
        }

if (SendResult.toString().contains("MESSAGE HAS BEEN SUBMITTED SUCCESSFULLY")) {
            System.out.println("Message sent to " + phoneNumber + " successfully.");
        } else {
            System.err.println("Message could not send to " + phoneNumber + ". Also check login credentials");
        }
        bufferedReader.close();

The problem is that even if the webpage contains the text MESSAGE HAS BEEN SUBMITTED SUCCESSFULLY, the condition always goes into ELSE part and show MESSAGE SENDING FAILED but thats not true because the message has been sent and i see the MESSAGE HAS BEEN SUBMITTED SUCCESSFULLY on the webpage.

Can anyone tell me where am i going wrong?
