How to set focus on JOptionPane

Question

Hello guys,
I create a
String options[] = {"Ok", "Cancle"};
JOptionPane.showOptionDialog(..,..,..,YES_NO,null,options, JTextField);
and inside this JOptionPane, there is a JTextField for receive what user input,
when I set this JTextField to be the default focus, the Ok and cancle button don't receive
action from Enter key, they are accepted only Mouse-clicked action.
Do you have another idea to make the button can accept the action from Enter key?

Answer 1

thank you, but I forgot to tell you that my JTextField is JPasswordField.
And we can't add keylistener to String, can we?
this is my code:
JTextField acodeField = new JPasswordField(12);
String[] buttonLabels = {"OK","Cancel"};
do
acodeField.setText("");
option = pane.showOptionDialog(this,
panel,
super.getTitle(),
JOptionPane.OK_CANCEL_OPTION,
JOptionPane.PLAIN_MESSAGE,
null,
buttonLabels,
acodeField);
// Quit operation if cancel button is selected.
if (option != 0 || option < 0) {
return option;
} while (authCode.compareTo(acodeField.getText()) != 0);
