Use Password Field Instead of using textfield

Answer 3

How exactly do I mask the user input with asterisks preserving its original value?

Use the JPasswordField which has nice function jPasswordField.getPassword(); to get the password as char[] to work with.

• Use jPasswordField1.setEchoChar('*') to mask the password characters with *.
• If you wish to see the value you are inserting use jPasswordField1.setEchoChar((char)0); Setting a value of 0 indicates that you wish to see the text as it is typed, similar to the behavior of a standard JTextField.
