本篇文章小编给大家分享一下Java二维数组实现数字拼图效果代码示例，文章代码介绍的很详细，小编觉得挺不错的，现在分享给大家供大家参考，有需要的小伙伴们可以来看看。
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;
}
}
