Add this line to your code,
jop.setInitialSelectionValue(password);
If you use a custom UI, you can replace the JTextField instance with a
JPasswordField instance by overriding the getMessage() method,
import javax.swing.plaf.basic.BasicOptionPaneUI;
...
class MyOptionPaneUI extends BasicOptionPaneUI {
class TextFieldActionListener implements ActionListener {
public void actionPerformed(ActionEvent e) {
optionPane.setInputValue(
((JTextField)e.getSource()).getText());
}
}
protected Object getMessage() {
Object sv = super.getMessage();
if (sv instanceof Object[] &&
((Object[])sv)[1] instanceof JTextField) {
JPasswordField pf = new JPasswordField();
pf.addActionListener(new TextFieldActionListener());
Object inputValue = optionPane.getInitialSelectionValue();
if (inputValue != null) {
String inputString = inputValue.toString();
pf.setText(inputString);
}
((Object[])sv)[1] = pf;
inputComponent = pf;
}
return sv;
}
}
JOptionPane jop = new ...
jop.setUI(new MyOptionPaneUI());
...
