将方法结合到tic tac toe板中

Question

到目前为止，这是我的代码：

import java.util.Scanner;
import java.util.Arrays;

public class TicTacToeGame {

    public static void main(String[] args) {
        // TODO Auto-generated method stub
        System.out.println("Welcome to Tic Tac Toe (you are X)!");
        String gameBox = new TicTacToe().toString();
        System.out.println(gameBox);
        userMove(gameBox);
    }


    public static void userMove(String gameBoard) {
        Scanner keyboard = new Scanner (System.in);
        int row, column;
        String [][] moveX = new String [3][3];
        do {
            System.out.print("Move location: ");
            row = keyboard.nextInt();
            column = keyboard.nextInt();
        } while (row < 0 || row > 2 || column < 0 || column > 2);
        for (int i = 0; i < moveX.length; i++){
            for (int j = 0; j < moveX[i].length; j++){
                if (row == i && column == j){
                    moveX[i][j] = "X";
                }
                else 
                    moveX[i][j] = " ";
            }
        }
        System.out.println(Arrays.deepToString(moveX));

    }

我让用户输入他们想要将X放在游戏板上的位置。游戏板gameBox（取自另一个类）看起来像这样：

=============
|   |   |   |
=============
|   |   |   |
=============
|   |   |   |
=============

我怎样才能获得＆＃34; X＆＃34;在游戏板里面？
