title: How to Remove an icon on a JButton?
body: <p>I'm trying to make a memory matching game, and I have icon images that I place onto a JButton when it is clicked. My question is, is there a way to remove the Icon from the JButton? I want to make so when a user clicks, the image is displayed, and if the second button the user clicks does not have the same image as the first button, then it disappears...any ideas?</p>
