How can I change the text that is actually displayed by a JTextArea?

Question

Hi. Does anyone know if there is a JTextArea method that I can override to change what is displayed on screen?

I want to keep the contents of the field the same. Ie. If I set the text to "hello" and I call getText(), I wan't it to return "hello".

However, I wan't to be able to override what is displayed on screen (Eg. to replace with '*')

Yes I know JPasswordField does this, but I need to use a JTextArea, and also would like fine control over what is displayed.

Any ideas? Is there a display method that I can override? Many many thanks if you have!!!

Manipulating User Data at the Model Layer in Swing

SUMMARY: Most of the graphical user interfaces (GUIs) developed with the Java Swing toolkit accept user input and validate it. Swing is built on the principle of the separable model architecture, a version of Model-View-Controller design where all of the graphical components have corresponding data model objects.

Part 1: Model-View-Controller and Swing

Document doc  = new DefaultStyledDocument();    // MODEL object
JTextArea ta1 = new JTextArea(doc);             // VIEW object 1
JTextArea ta2 = new JTextArea(doc);             // VIEW object 1
