如何使用int数组编写我的取胜方法

public class TicTacToe {
    private int[][] board;
    private int currentPlayer;

    public TicTacToe() {
        board = new int[3][3];
        currentPlayer = 1;
    }

    public void makeMove(int row, int col) {
        if (board[row][col] == 0) {
            board[row][col] = currentPlayer;
            currentPlayer = currentPlayer == 1 ? 2 : 1;
        }
    }

    public boolean checkWin() {
        // 检查行
        for (int i = 0; i < 3; i++) {
            if (board[i][0] != 0 && board[i][0] == board[i][1] && board[i][1] == board[i][2]) {
                return true;
            }
        }

        // 检查列
        for (int j = 0; j < 3; j++) {
            if (board[0][j] != 0 && board[0][j] == board[1][j] && board[1][j] == board[2][j]) {
                return true;
            }
        }

        // 检查对角线
        if (board[0][0] != 0 && board[0][0] == board[1][1] && board[1][1] == board[2][2]) {
            return true;
        }
        if (board[0][2] != 0 && board[0][2] == board[1][1] && board[1][1] == board[2][0]) {
            return true;
        }

        return false;
    }
}
