我的井字游戏中的非法表达开始

Question

我在打井字问题时遇到了一些麻烦。我检查了我的代码很多次，但是找不到问题。我仔细检查了所有的括号和括号。当我在命令行中运行它时，它表示存在表达式和';'的非法使用。预期。我想知道是否可以发现问题。

输入：

import java.util.Scanner;

public class TicTacToe
{
    public static int row, col;
    public static Scanner scan = new Scanner(System.in);
    public static char[][] board = new char[3][3];
    public static char playerTurn = 'X';

    public static void main(String[] args)
    {
        // Implement play method
        for(int i = 0; i < 3; i++)
        {
            for(int j = 0; j < 3; j++)
            {
                board[i][j] = '_';
            }   
        }
        Play();
    }

    public static void Play() 
    {
        boolean playing = true;
        System.out.println("Player X's turn to play! ");

        // Implement print board method
        while(playing)
        {
            System.out.println("\nEnter row and column ");
            row = scan.nextInt()-1;
            col = scan.nextInt()-1;
            board[row][col]=playerTurn;

            if(GameOver(row,col))
            {
                playing = false;
                System.out.println("Game over! player" + playerTurn + " wins! ");
            }
