    Default

    I do not see why you can't use a JPasswordField, but that aside one way would be to extend one of the classes which implement the Document interface and override a few of its methods (remove, insertString, getText(), etc...). You can keep a StringBuilder variable which holds the true password value and is modified by the override methods, but in insertString call the super method to insert *'s. Why do all this when its done for you in a JPasswordField though.
