public class JPasswordField
extends JTextField   

JPasswordField 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. You can find further information and examples in How to Use Text Fields, a section in The Java Tutorial.

JPasswordField is intended to be source-compatible with java.awt.TextField used with echoChar set. It is provided separately to make it easier to safely change the UI for the JTextField without affecting password entries.

Warning: Serialized objects of this class will not be compatible with future Swing releases. The current serialization support is appropriate for short term storage or RMI between applications running the same version of Swing. As of 1.4, support for long term storage of all JavaBeans^TM has been added to the java.beans package. Please see XMLEncoder .
