爪哇 | 将 2D int 数组转换为 2D char 数组以用于 println

Question

我正在尝试将二维整数数组转换为二维字符数组。我用下面的代码到目前为止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请帮帮我？

Answer 1

您的int转换char不正确，应该只需要强制转换。这

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

应该

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

通过这一改变，我得到了一个像这样的棋盘
