Updating text on a JButton

Question

is it posible to update text on a JButton before the actionPerformed method has completed??
to put this into context if two buttons have been assigned names, by clicking on the button the names are displayed (as labels by saying button.setText(button.getName());. Can you then check if the names are the same, and if not set the labels to "?"

Answer 1

Not quite sure I understand what you need, but is this any use?
When the button is pressed, if it's name is not the same as it's text
a "?" is shown, when released the text is restored.
