public class JPasswordField
extends JTextField
JTextField is a lightweight component that allows the editing of a single line of text where the view indicates something was typed, but does not show the original characters. It is intended to be source-compatible with java.awt.TextField used with echoChar set. It is provided seperately to make it easier to safely change the ui for the JTextField without affecting password entries.
