Java 1.4

serializable

This Callback class represents a request for a password. A CallbackHandler should handle it by displaying the prompt returned by getPrompt( ) and then allowing the user the enter a password. When the user has entered the password, it should pass the entered text to setPassword( ) . If isEchoOn( ) returns true, then the Handler should display the password as the user types it.
