JTextField + JTextArea -> Problem with backspace-ing

[Kemal Sokolovic]

I was working on simple Swing application, and I got stuck - again! The application is something similar to Windows Command Prompt.
This is the deal now:
I have a JTextField where user can enter command; the response is shown in the JTextArea above it.
I am waiting for the command in the field until user presses Enter key. After that some logic is invoked, and result is displayed inside of JTextArea. I also have one more event assocciated with JTextField - when any key is pressed, character pressed is appended to text in JTextArea, so it lookes like user is typing command in JEditorPane. And now, I don't know how can I make application remove last entered characted from JTextArea if user presses Backspace (just in case user wants to change/correct entered command)?
One way might be to retreive all the text from text area, then "manually" remove last character and then set new text again. But, I was wondering if there is a "more ellegant" way to do that?

Thanks!

Get the field's Document and use remove and getLength to remove the final character.

Here is the solution, someone might use the idea later:

  
if(evt.getKeyCode() == KeyEvent.VK_BACK_SPACE) {
      Document doc = terminalArea.getDocument();
      int position = doc.getLength() - 1;
      try {
          doc.remove(position, 1);
      } catch (BadLocationException ex) {
          //
      }
}

@Rob: Thanks for directions!
