Java编程实现五子棋人人对战代码示例
代码如下：
import java.util.Scanner;
public class Gobang {
private static final int BOARD_SIZE = 15; //棋盘大小
private String[][] board = new String[BOARD_SIZE][BOARD_SIZE]; //棋盘数组
//初始化棋盘，所有格子都用"＋"符号表示
public void initBoard() {
for(int i=0; i<BOARD_SIZE; i++) {
for(int j=0; j<BOARD_SIZE; j++) {
board[i][j] = "＋";
}
}
}
//在控制台上打印棋盘
public void printBoard() {
for(int i=0; i<BOARD_SIZE; i++) {
for(int j=0; j<BOARD_SIZE; j++) {
System.out.print(board[i][j]);
}
System.out.println();
}
}
//玩家落子的方法
public void playerPutChess(String chess) {
Scanner scanner = new Scanner(System.in);
System.out.println("请输入您要落子的位置，格式如：5,5");
String inputStr = scanner.nextLine();
String[] posStrArr = inputStr.split(",");

int posY = Integer.parseInt(posStrArr[1]) - 1;

}
}
//判断游戏是否结束

}

}
//判断一行是否有五子连珠
