I have a simple game that is in progress. As of right now all I want to do is click the green button and have the fifth and third pieces switch places. The paintComponent is called after the swap in the arraylist is made, but the JPanel is not refreshed to show these changes. When i am running my application I am choosing 4 for the pieces for each side. Thus, the inner green and black pieces should change place. Please help.
