Java Swing Restart Timer After Operation

Question

I need my timer to restart or at least add another delay after a certain line of code is performed.

private static class ButtonHandler implements ActionListener

I was going to post this into your previous question, but it seems you've some progress, well done.

Okay, so, this example gives you three buttons to choose from. When you click one, it records what you choose, disables the buttons and starts a Timer which waits 1 second.

The Timer's ActionListener then checks to see what you choose and updates the output, then starts another Timer which waits 1 second, which then re-enables the buttons...

    }
