java - How do you reveal the text of a JPasswordField

Question

I'm making a Authentication app in java and i want to add a JRadioButton, where if it is selected it will allow you to see the text in the JPasswordField, i was trying to figure it out and i was just wondering is there any way to do it?

Answer 1

From the Java-Doc of the setEchoChar() method:

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.

So just use:

second.setEchoChar((char)0);

to set and to reset:

second.setEchoChar('\u2022');

The default EchoChar is determined by the Look & Feel. To be always in harmony with the theme it's the best to save the default EchoChar before changing it the first time:

char originalEchoChar = second.getEchoChar();
