二维数组实现数字拼图，供大家参考，具体内容如下
二维数组可以自己随意定义大小，通过方法判断来实现对所有的数字进行随机打乱，并可以通过移动来正确还原，并可以判断0（表示空格）是否可以移动，是否在范围内。
public static void main(String[] args) { Scanner scanner = new Scanner(System.in); int[][] arrays = { { 1, 2, 3 }, { 4, 5, 6 }, { 7, 8, 0 } }; int sum = 1; String direction; bianLi(arrays); daLuanErWeiShuZu(arrays); System.out.println("========================================"); while (true) { bianLi(arrays); if (isOk(arrays)) { break; } sum++; try { Thread.sleep(500); } catch (InterruptedException e) { // TODO Auto-generated catch block e.printStackTrace(); } System.out.println("请输入移动方向(W 上、S 下、A 左、D 右)"); direction = scanner.next(); switch (direction) { case "W": case "w": tiHuanShuZuWeiZhi(returnX(arrays), returnY(arrays), "上", arrays); break; case "S": case "s": tiHuanShuZuWeiZhi(returnX(arrays), returnY(arrays), "下", arrays); break; case "A": case "a": tiHuanShuZuWeiZhi(returnX(arrays), returnY(arrays), "左", arrays); break; case "D": case "d": tiHuanShuZuWeiZhi(returnX(arrays), returnY(arrays), "右", arrays); break; default: System.out.println("非法输入，重新输入"); break; } } System.out.println("一共走了" + sum + "步"); System.out.println("挑战成功");}
判断当前坐标是否可以移动
/** * 判断当前坐标是否可以移动 * * @param arrays * @return 可以移动返回true */ public static boolean isYiDong(int[][] arrays) { int returnX = returnX(arrays); int returnY = returnY(arrays); System.out.println(returnX + ":" + returnY); if (returnX >= 0 && returnX + 1 < arrays.length && returnY >= 0 && returnY + 1 < arrays.length) { return true; } return false; }
获取当前0所在行的具体地址
// 获取0所在行的位置 public static int returnX(int[][] arrays) { for (int i = 0; i < arrays.length; i++) { for (int j = 0; j < arrays[i].length; j++) { if (0 == arrays[i][j]) { return i; } } } return -1; }
获取当前0所在列的具体地址
// 获取0所在列的位置 public static int returnY(int[][] arrays) { for (int i = 0; i < arrays.length; i++) { for (int j = 0; j < arrays[i].length; j++) { if (0 == arrays[i][j]) { return j; } } } return -1; }
二维数组随机打乱，需要判断左上角、右上角、左下角、右下角、中间、上中、下种、左中、右中，那些方向可以移动，生成随机数来确定移动方向
// 二维数组随机打乱 public static void daLuanErWeiShuZu(int[][] arrays) { for (int i = 0; i < arrays.length; i++) { for (int j = 0; j < arrays[i].length; j++) { // 左上 if (i == 0 && j == 0) { // 根据生成的随机数确定向右边边移动还是向下移动 if (ouShuOrJiShu()) { tiHuanShuZuWeiZhi(i, j, "下", arrays); } else { tiHuanShuZuWeiZhi(i, j, "右", arrays); } } // 右上 if (i == 0 && j == arrays[0].length - 1) { // 根据生成的随机数确定向左边边移动还是向下移动 if (ouShuOrJiShu()) { tiHuanShuZuWeiZhi(i, j, "下", arrays); } else { tiHuanShuZuWeiZhi(i, j, "左", arrays); } } // 左下 if (i == arrays.length - 1 && j == 0) { // 根据生成的随机数确定向左边边移动还是向下移动 if (ouShuOrJiShu()) { tiHuanShuZuWeiZhi(i, j, "上", arrays); } else { tiHuanShuZuWeiZhi(i, j, "右", arrays); } } // 右下 if (i == arrays.length - 1 && j == arrays[i].length - 1) { // 根据生成的随机数确定向左边边移动还是向下移动 if (ouShuOrJiShu()) { tiHuanShuZuWeiZhi(i, j, "上", arrays); } else { tiHuanShuZuWeiZhi(i, j, "左", arrays); } } // 上中 if (i == 0 && j > 0 && j < arrays[i].length - 1) { switch (oneToThree(3)) { case 0: tiHuanShuZuWeiZhi(i, j, "右", arrays); break; case 1: tiHuanShuZuWeiZhi(i, j, "下", arrays); break; case 2: tiHuanShuZuWeiZhi(i, j, "左", arrays); break; default: break; } } // 左中 if (j == 0 && i > 0 && i < arrays.length - 1) { switch (oneToThree(3)) { case 0: tiHuanShuZuWeiZhi(i, j, "上", arrays); break; case 1: tiHuanShuZuWeiZhi(i, j, "右", arrays); break; case 2: tiHuanShuZuWeiZhi(i, j, "下", arrays); break; default: break; } } // 下中 if (i == arrays.length - 1 && j > 0 && j < arrays[i].length - 1) { switch (oneToThree(3)) { case 0: tiHuanShuZuWeiZhi(i, j, "上", arrays); break; case 1: tiHuanShuZuWeiZhi(i, j, "右", arrays); break; case 2: tiHuanShuZuWeiZhi(i, j, "左", arrays); break; default: break; } } // 右中 if (j == arrays[i].length - 1 && i > 0 && i < arrays[i].length - 1) { switch (oneToThree(3)) { case 0: tiHuanShuZuWeiZhi(i, j, "上", arrays); break; case 1: tiHuanShuZuWeiZhi(i, j, "左", arrays); break; case 2: tiHuanShuZuWeiZhi(i, j, "下", arrays); break; default: break; } } if (i > 0 && j > 0 && i < arrays.length - 2 && j < arrays[i].length - 2) { switch (oneToThree(4)) { case 0: tiHuanShuZuWeiZhi(i, j, "上", arrays); break; case 1: tiHuanShuZuWeiZhi(i, j, "右", arrays); break; case 2: tiHuanShuZuWeiZhi(i, j, "下", arrays); break; case 3: tiHuanShuZuWeiZhi(i, j, "左", arrays); break; default: break; } } } } }
该方法实现对0的位置和需要替换位置数据的替换，并对0范围进行验证，怕0出现数组下标越位。
/** * 根据输入的数据，对二维数组进行数据替换 * * @param i 高位坐标 * @param j 地位坐标 * @param direction 移动方向 * @param arrays 需要交换数据的数组 */ public static void tiHuanShuZuWeiZhi(int i, int j, String direction, int[][] arrays) { int tem = -1; switch (direction) { case "上": if (i > 0) { tem = arrays[i][j]; arrays[i][j] = arrays[i - 1][j]; arrays[i - 1][j] = tem; } break; case "下": if (i < arrays.length - 1) { tem = arrays[i][j]; arrays[i][j] = arrays[i + 1][j]; arrays[i + 1][j] = tem; } break; case "左": if (j > 0) { tem = arrays[i][j]; arrays[i][j] = arrays[i][j - 1]; arrays[i][j - 1] = tem; } break; case "右": if (j < arrays.length - 1) { tem = arrays[i][j]; arrays[i][j] = arrays[i][j + 1]; arrays[i][j + 1] = tem; } break; default: break; } }
