Controlling the display of text in a JTextField

[peahead]

I have the following routine:

  private void getEngineOutput(Process engine) {
    try {
      BufferedReader reader =
        new BufferedReader(new InputStreamReader(engine.getInputStream()), 1);
      String lineRead = null;
      while((lineRead = reader.readLine()) != null) {
    	
        textArea.append(lineRead);
        textArea.append("\n");
        textArea.setCaretPosition(textArea.getDocument().getLength() - 0);
        System.out.println(lineRead);

      }
    
    }
    catch(Exception e) {
      e.printStackTrace();
    }
  }

It produces lines of data as follows:

	5     31       0   2250  1. e4 Nc6 2. Nc3 Nf6 3. d4
	5     31       0   2853  1. e4 Nc6 2. Nc3 Nf6 3. d4
	6      9       0   3192  1. e4 Nc6 2. Nc3 Nf6 3. d4 Bd6
	6      9       2   4298  1. e4 Nc6 2. Nc3 Nf6 3. d4 Bd6
	7     49       2   6336  1. e4!

Is it possible to 'reverse' the output routine so that data outputs/prints at the top of the JTextField as opposed to outputting at the bottom? Using the above, I would like the data to print out as follows...

	7     49       2   6336  1. e4!
	6      9       2   4298  1. e4 Nc6 2. Nc3 Nf6 3. d4 Bd6
	6      9       0   3192  1. e4 Nc6 2. Nc3 Nf6 3. d4 Bd6
	5     31       0   2853  1. e4 Nc6 2. Nc3 Nf6 3. d4
	5     31       0   2250  1. e4 Nc6 2. Nc3 Nf6 3. d4
