我正在嘗試將二維整數(shù)數(shù)組轉(zhuǎn)換為二維字符數(shù)組。我用下面的代碼到目前為止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：我無(wú)法將 int[][] boardArray 更改為 char][] boardArray請(qǐng)幫幫我？

您的int轉(zhuǎn)換char不正確，應(yīng)該只需要強(qiáng)制轉(zhuǎn)換。這
arr[i][j] = Integer.toString(boardArray[i][j]).charAt(0);
應(yīng)該
arr[i][j] = (char) boardArray[i][j];
通過這一改變，我得到了一個(gè)像這樣的棋盤
