Question

那是我的tictactoe游戏，我有这个问题我找不到...当我编译我的程序时欢迎来到井字教授Falken！

_1_|_2_|_3_|

_4_|_5_|_6_|

_7_|_8_|_9_|

  You Go First!

___|___|___|

___|___|___|

___|___|___|

Player X, enter move (1 - 9):

10

INVALID MOVE: Enter number 1 - 9 only:

5

___|___|___|

___|_X_|___|

___|___|___|

Player O, enter move (1 - 9):

___|___|___|

然后停在那儿，我不知道为什么有人可以帮助我？

我在move和checkMove上做了一些更改

public void move() {
    int move = 0;
    Boolean valid = false;
    System.out.println("Player " + turn + ", enter move (1 - 9): ");
    if (turn == 'O') {
        move = randomNumber;
    } else {
        move = in.nextInt();
    }

    valid = checkMove(move);
    while (!valid) {
        if (turn == 'X') {
            move = in.nextInt();
        } else {
            move = random.nextInt(9);
        }
        valid = checkMove(move);
    }

    count++;
    board[(move - 1) / 3][(move - 1) % 3].piece = "_" + turn + "_|";
    board[(move - 1) / 3][(move - 1) % 3].player = turn;
    board[(move - 1) / 3][(move - 1) % 3].used = true;

    printBoard();

    if (count >= 5) {
        checkWin(move);
    }
    if (turn == 'X') {
        turn = 'O';
    }else {
        turn = 'X';
    }
}

public Boolean checkMove(int move) {
    if (move < 1 || move > 9) {
        System.out.println("INVALID MOVE: Enter number 1 - 9 only: ");
        return false;
    }else if (board[(move - 1) / 3][(move - 1) % 3].used) {
        System.out.println("INVALID MOVE: That move has been used. Enter another move (1 - 9): ");
        return false;
    }else {
        return true;
    }
}
