Java二维数组实现数字拼图效果

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 blocke.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; }

【Java二维数组实现数字拼图效果】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; } }
