Question

我为Minesweeper创建代码并尝试实现GUI。但问题是，当我运行代码并玩游戏时，我点击棋盘上的位置会显示答案板上该位置的y，x坐标，而不是x，y坐标。我一直试图解决这个问题但我无法弄明白这一点。我认为这可能是我创建董事会的方式，但我尝试了我能想到的一切。

class Board{

public MsGUI gui;

private static char[][] userBoard;
private static char[][] solutionBoard;
private static int boundSize = 5;

public Board(){
 userBoard = new char[][]   {{'-','-','-','-','-'},
                              {'-','-','-','-','-'},
                              {'-','-','-','-','-'},
                              {'-','-','-','-','-'},
                              {'-','-','-','-','-'}};  

 solutionBoard = new char[][] {{'0','2','B','2','0'},
                {'0','3','B','3','0'},
                {'1','3','B','3','1'},
                {'B','1','3','B','2'},
                {'1','1','2','B','2'}};

 return;
    }

Answer 1

初始化solutionBoard的方式并非您所期望的那样。如果你得到solutionBoard [0]，你就不会访问第一列（这与我认为你理解的一致），但是第一行（二维数组的第一项）：{'0'， '2'， 'B'， '2'， '0'}

因此，如果您希望x为行索引，y为列索引，并且仍然保持这种“可读”初始化，则每次访问数组时都必须交换索引。但这只会帮助你解决一个问题 - 一开始是人类可读的阵列分配，但我想你将来会对这个决定感到遗憾。

编辑：您可以根据需要初始化数组，并仍然使用这样的可读格式：

String readableBoard =
            "0 2 B 2 0;" +
            "0 3 B 3 0;" +
            "1 3 B 3 1;" +
            "B 1 B B 2;" +
            "1 1 2 B 2";
char[][] board = initBoard(readableBoard);

....

private char[][] initBoard(String readableBoard){
    char[][] board = new char[5][5];
    String[] rows = readableBoard.split(";");
    String[] fields = null;
    for (int y = 0; y<rows.length;y++){
        fields = rows[y].split(" ");
        for (int x = 0; x<fields.length; x++){
            board[x][y]=fields[x].charAt(0);
        }
    }
    return board;
}

现在打电话

board[2][0]

你会得到'B'

Answer 2

如果你看看你的嵌套for循环，你打印的是列，而不是我认为是所需的行。尝试切换for循环以迭代y，然后x。

   for (int y = 0; y < boundSize; y++){
    for(int x = 0; x < boundSize; x++){
        System.out.print(" " + Character.toString(board[x][y]));
    }
    System.out.println("");
}        

System.out.println("");

在2d阵列上的扫雷程序java x和y被切换
