java - 带二维数组的 TicTacToe

Question

我的教授希望这段代码打印出井字游戏板，但我不完全确定从这里做什么。这是我尝试过的:

public static void main(String[] args) {
    Scanner keyboard = new Scanner(System.in);

    char[][] board = new char[3][3];
    boolean hasWinnerOrStaleMate = false;

    while (!hasWinnerOrStaleMate) {
        int row;
        int col;
        boolean setLocation = false;
        do {
            row = keyboard.nextInt();
            col = keyboard.nextInt();

            if (board[row][col] == '\u0000') // vacant
            {
                board[row][col] = 'X';
                setLocation = true;
            } else {
                System.out.println("Occupied Try again");
            }
        } while (!setLocation);

        for (row = 0; row < board.length; row++) {
            for (col = 0; col < board.length; col++) {
                System.out.print(board[row][col]);
            }
        }
    }

}

Answer 1

这里给你一个提示:当你打印数组时，你应该在打印完一行后打印换行符。

for (row = 0; row < board.length; row++) {
    for (col = 0; col < board.length; col++) {
        System.out.print(board[row][col]);
    }
    System.out.println();
}

剩下的部分我留给读者作为练习。
