    Default JTextField:four digit in the middle displayed as wildcard while user type the number

    hi all,

    I am developing a Swing application which use JTextField to let user input telephone number. For security, the four digit in the middle need to be displayed as wildcard while user type the phone number. At meanwhile, this JTextField also show the four digit in the middle as wildcard when the phone number is from database .

    How to customize the JTextField? Any help are highly appreciated.
