Question

我正在尝试将int的2D数组转换为chars的2D数组。

我已经用下面的代码做到了这一点

int[][] boardArray = {
  {0x265C, 0x265E, 0x265D, 0x265B, 0x265A, 0x265D, 0x265E, 0x265C},
  {0x265F, 0x265F, 0x265F, 0x265F, 0x265F, 0x265F, 0x265F, 0x265F},
  {0, 0, 0, 0, 0, 0, 0, 0},
  {0, 0, 0, 0, 0, 0, 0, 0},
  {0, 0, 0, 0, 0, 0, 0, 0},
  {0, 0, 0, 0, 0, 0, 0, 0},
  {0x2659, 0x2659, 0x2659, 0x2659, 0x2659, 0x2659, 0x2659, 0x2659},
  {0x2656, 0x2658, 0x2657, 0x2655, 0x2654, 0x2657, 0x2658, 0x2656}};

char[][] arr = new char[boardArray.length][];
for(int i = 0; i < boardArray.length; i++) {
arr[i] = new char[boardArray[i].length];
  for(int j = 0; j < boardArray[i].length; j++){
    arr[i][j] = Integer.toString(boardArray[i][j]).charAt(0);
  }
}

System.out.println(Arrays.deepToString(arr)
  .replaceAll("\\[|,", "")
  .replace("] ", ""+System.lineSeparator())
  .replace("]]", ""));

限制：

我无法将int [] [] boardArray更改为char] [] boardArray

这是我得到的： https://i.stack.imgur.com/wHb6L.jpg

请帮我吗？

您的从int到char的转换是不正确的，应该只需要强制转换。这个

arr[i][j] = Integer.toString(boardArray[i][j]).charAt(0);

应该是

arr[i][j] = (char) boardArray[i][j];

有了这样的改变，我得到了像棋盘一样的棋子
