为我的扫雷代码打印 "labels" 时遇到问题

Question

我正在写扫雷游戏，我正在为 the following method- you can also look at the code below. I pass in a smaller map and I put in a new array but I'm struggling with the logic of how to get the 0 column and 0 row to print out like in this example 苦苦挣扎。你可以在下面看到我的一些代码。尽管我无法真正让它按照我预期的方式工作。

/**
 * This prints out the map. This shows numbers of the columns
 * and rows on the top and left side, respectively. 
 * map[0][0] is row 1, column 1 when shown to the user.
 * The first column, last column and every multiple of 5 are shown.
 * 
 * To print out a 2 digit number with a leading space if the number
 * is less than 10, you may use:
 *     System.out.printf("%2d", 1); 
 * 
 * @param map The map to print out.
 */
public static void printMap(char[][] map) {
  char[][] mapWithNum = new char[map.length + 1][map[0].length + 1];
  for (int i = 1; i < mapWithNum.length; i++) {
    for (int j = 1; j < mapWithNum[0].length; j++) {
      mapWithNum[i][j] = map[i - 1][j - 1];
    }
  }
  for (int i = 0; i < mapWithNum.length; i++) {
    for (int j = 0; j < mapWithNum[0].length; j++) {
      if (i == 0 || j == 0) {
        if (i == 0 && j == 0) {
          System.out.print("  ");
        } else if (j == 1 && i == 0) {
          System.out.print(" " + j);
        } else if ((j) % 5.0 == 0) {
          System.out.print(" t1" + (j));
          if (j == map.length - 1 && i == 0) {
            System.out.print(" t2" + (j + 1));
          }
        } else {
          System.out.print("--");
          if (j == map.length - 1 && i == 0) {
            System.out.print(" t2" + (j + 1));
          }
        }


      } else {
        System.out.print(" " + mapWithNum[i][j]);
      }
      /* if (j == 1) {
        if (j % 5 == 0) {
         System.out.print(" " + (i + 1));
        }
        else {
         System.out.print('-');*/
      //}
      // }
    }
    System.out.println();
  }

  return;
}

如有任何帮助，我们将不胜感激。

您不需要在您的方法中创建新的二维数组。只需循环原来的那个。 printMap() 方法应该做的第一件事是打印初始 header 行：" 1------ 5--------10"。这很简单，即使您必须使其动态化。接下来，正常循环遍历二维数组。在打印每一行之前，打印行前缀。例如，数组第一行的前缀是 " "。第二行的前缀是 " 1 "。等等。请注意，第 0、4、9 行...有不同的情况。其他行的前缀只是 " | "。使用 printf() 进行格式化会有所帮助。您应该在进入内部循环之前打印前缀。还要记住不要打印带有前缀的换行符。您的内部循环应该从前缀停止的地方继续。最后，内部循环应该打印数组的每个元素。但是记得在打印的时候给每个元素加上一个" "。我建议先尝试只打印点。然后添加 header 行，最后添加行前缀。
