Question

我在Tic Tac Toe Java程序的代码中遇到了挫折。每次我运行它，游戏板打印3次，第二次打印，X都填写一行表示玩家X获胜。我一直试图解决这个问题，但我仍然无法找到问题。我要问的是，代码打印出来的主要问题是什么，而不是填写内容？

我希望我正确格式化。

import java.util.Scanner;

public class TicTacToeWork {

    //Variable declaration.
    public static char[][] GameBoard = new char[3][3];
    public static Scanner keyboard = new Scanner(System.in);
    public static int column, row;
    public static char PlayerTurn = 'X';

    public static void main(String args[]) {

        for (int i = 0; i > 3; i++) {

            for (int j = 0; j < 3; j++) {
                GameBoard[i][j] = '_';
            }
        }
        System.out.println("Enter coordinates of row then column to choose your space.");
        Playing();
    }

    public static void Playing() {

        boolean PlayerPlaying = true;

        while (PlayerPlaying) {
            boolean playing = true;

            while (playing) {
                row = keyboard.nextInt() - 1;
                column = keyboard.nextInt() - 1;
                GameBoard[row][column] = PlayerTurn;

                if (EndGame(row, column)) {
                    playing = false;
                    System.out.println("Game over player " + PlayerTurn + " wins!");
                }
                BoardPrint();

                if (PlayerTurn == 'X') {
                    PlayerTurn = 'O';
                } else {
                    PlayerTurn = 'X';
                }
            }
        }
    }

    public static void BoardPrint() {

        //Print out the game board.
        for (int i = 0; i < GameBoard.length; i++) {
            for (int n = 0; n < 3; n++) {
                System.out.println();

                for (int j = 0; j < 3; j++) {

                    if (j == 0) {
                        System.out.print("| ");
                    }
                    System.out.print(GameBoard[i][j] + " | ");
                }
            }
            System.out.println();
        }
        System.out.println();
    }

    public static boolean EndGame(int RowMove, int ColumnMove) {

        //Deciding factors on who wins and ties.
        if (GameBoard[0][ColumnMove] == GameBoard[1][ColumnMove]
                && GameBoard[1][ColumnMove] == GameBoard[2][ColumnMove]) {
            return true;
        }
        if (GameBoard[RowMove][0] == GameBoard[1][RowMove]
                && GameBoard[RowMove][0] == GameBoard[RowMove][2]) {
            return true;
        }
        if (GameBoard[0][0] == GameBoard[1][1] && GameBoard[0][0] == GameBoard[2][2]
                && GameBoard[1][1] != '_') {
            return true;
        }
        if (GameBoard[0][2] == GameBoard[1][1] && GameBoard[0][2] == GameBoard[2][0]
                && GameBoard[1][1] != '_') {
            return true;
        } else {
            return false;
        }
    }
}

你的BoardPrint方法都错了。你必须做这样的事情..

public static void BoardPrint() {
    System.out.println("-------------");

    for (int i = 0; i < 3; i++) {
        System.out.print("| ");

        for (int j = 0; j < 3; j++) {
            System.out.print(GameBoard[i][j] + " | ");
        }
        System.out.println();

        System.out.println("-------------");
    }

您还必须重做支票以获得胜利。

一点提示..你没有正确使用布尔方法。这句话if(EndGame(row, column))表示如果EndGame为真则停止游戏。您设置方法的方式是没有正确地进行检查。你不得不说“如果不是真的” - 所以它看起来像这样if(!EndGame(row, column))还有其他一些错误，但这应该会给你一个完成项目的良好开端。
