(Game: connect four) Programming Exercise 7.20 enables two players to play the connect-four game on the console. Rewrite the program using an applet, as shown in Figure 18.34c. The applet enables two players to place red and yellow discs in turn. To place a disk, the player needs to click on an available cell. An available cell is unoccupied and its downward neighbor is occupied. The applet flashes the four winning cells if a player wins and reports no winners if all cells are occupied with no winners.

(Game: connect four) Connect four is a two-player board game in which the players alternately drop colored disks into a seven-column, six-row vertically suspended grid, as shown below.
