Java - 带有二维数组的TicTacToe游戏

Question

我试图创建一个Tic Tac Toe游戏，用户实际上输入了主板并且程序告诉他哪一方获胜，或者是否有抽奖，而不是在棋盘上没有任何内容。 。使用二维数组，我想让用户输入是一个单独的行，然后取出字符并将它们放入数组中。该程序将根据通过while循环的次数确定输入字符的位置。但是，我遇到了多个问题：程序不只需要3个输入，需要更多，并且当输入的长度不是3时，应该提出错误信息有时显示。最后，当阵列显示时，它会显示数字而不是x和o。

import java.util.*;
public class TicTacToe {
    public static void PrintingRow(int[] row) { // we define how we want the board to be displayed (i.e. no brackets and no commas.)

        for (int i : row) {
            System.out.print(i); }
        System.out.println();
        } 

    public static void main(String[] args) {
        int TicTac[][]= new int[3][3];

        System.out.println("Enter the Tic Tac Toe board you want to see, one line at a time.");
        Scanner scanner = new Scanner(System.in);

        int loop = 0;

            while (loop != 3) { // we count the loops so that there's only 3 different lines
                String ticTacLine = scanner.nextLine();
                if (ticTacLine.length() != 3) {  // I try to define the array by a series of inputs that go in the while loop.
                    System.out.println("Tic-tac-toe plays in a 3×3 grid. This means if you want to input a line, you would want to input 3 characters, no more, no less.");

                } else {
                    char uno = ticTacLine.charAt(0);
                    char dos = ticTacLine.charAt(1);
                    char tres = ticTacLine.charAt(2);

                    if ((uno != 'x' && uno != 'o') || (dos != 'x' && dos != 'o') || (tres != 'x' && tres != 'o')) {
                        System.out.println("Have you never played Tic Tac Toe before ? It's okay if you haven't, but just FYI, it plays with x's and o's.");
                        break;
                    } else { 
                        if (loop == 0) {
                            TicTac[0][0] = uno;
                            TicTac[0][1] = dos;
                            TicTac[0][2] = tres;
                            loop = ++loop;
                            ticTacLine = scanner.nextLine();
                        } else if (loop == 1) {
                            TicTac[1][0] = uno;
                            TicTac[1][1] = dos;
                            TicTac[1][2] = tres;

                        } else if (loop == 2) {
                            TicTac[2][0] = uno;
                            TicTac[2][1] = dos;
                            TicTac[2][2] = tres;
                            loop = ++loop;
                            ticTacLine = scanner.nextLine();
                            }
                        }
                    }
                } 
            if (loop == 3) {
                for(int[] row : TicTac) {
                    PrintingRow(row);
                    } }
        // Here we want to check what character won (x's or o's)


            }
