/** * Represents the state of a Connect Four board on which multiple games can be played. The board consists of a * rectangular grid of squares in which playing pieces can be placed. Squares are identified by their zero-based row and * column numbers, where rows are numbered starting with the bottom row, and columns are numbered by starting from the * leftmost column. * * Multiple games can be played on a single board. Whenever a new game begins, the board is empty. There are two * players, identified by the constants P1 (Player 1) and P2 (Player 2). P1 moves first in the first game, P2 moves * first in the second game, and so on in alternating fashion. * * A C4Board also keeps track of the outcomes of the games that have been played on it. It tracks the number of wins by * P1, the number of wins by P2, and the number of ties. It does not track games that were abandoned before being * completed. */ public class C4Board { /** The number used to indicate Player 1 */ public static final int P1 = 1;
