Java Applet Tic-Tac-String game-how to start again? (Leave problem)

Today in the textbook to see the source of the applet tic-tac-Small game, but did not restart this function, I am prepared to write a Isrepaint () method to pop-up dialog box to ask the player whether to start again, but will not initialize the game, left to solve later.

If there is a passing master greatly, look at the liberal enlighten, Green bamboo grateful!
