实现原理

扫雷实现第一步就是生成棋盘，第二步就要生成每个棋子，定义棋子属性是否是地雷，第三部就是给不是地雷的棋子赋值（附近多少地雷）。

/*** 扫雷棋盘*/
public class DemoTest {public static void main(String[] args) {int[][] arrs = generate();print(arrs);}private static void print(int[][] arrs) {if (arrs == null || arrs.length == 0) {return;}for (int i = 0; i < arrs.length; i++) {for (int j = 0; j < arrs[i].length; j++) {if (arrs[i][j] == -2) {System.out.print("P ");}else {System.out.print(arrs[i][j] + " ");}}//换行打印System.out.println();}}private static int[][] generate() {Scanner in =new Scanner(System.in);//设置棋盘的大小System.out.println("请输入棋盘大小：");int a = in.nextInt();if (a <= 0) {System.out.println("棋盘大小必须大于0");return null;}//设置地雷的个数System.out.println("请设置地雷的个数：");int b = in.nextInt();if (b < 0) {System.out.println("地雷个数必须大于0");return null;}else if (b > a*a) {System.out.println("地雷个数必须小于" + a*a);return null;}int[][] arrs = new int[a][a];//地雷标记位-2，其它标记为-1Random r = new Random();for (int i = 0; i < arrs.length; i++) {for (int j = 0; j < arrs[i].length; j++) {if (b > 0) {boolean flag = r.nextBoolean();if (flag) {arrs[i][j] = -2;b --;}else {arrs[i][j] = -1;}}else {arrs[i][j] = -1;}}}for (int i = 0; i < arrs.length; i++) {for (int j = 0; j < arrs[i].length; j++) {if (i == 0) {if (j == 0) {if (arrs[i][j] == -1) {int count = 0;if (arrs[i+1][j] == -2) {count ++;}if (arrs[i+1][j+1] == -2) {count ++;}if (arrs[i][j+1] == -2) {count ++;}arrs[i][j] = count;}}else if(j == arrs[i].length -1){if (arrs[i][j] == -1) {int count = 0;if (arrs[i][j-1] == -2) {count ++;}if (arrs[i+1][j-1] == -2) {count ++;}if (arrs[i+1][j] == -2) {count ++;}arrs[i][j] = count;}}else{if (arrs[i][j] == -1) {int count = 0;if (arrs[i][j-1] == -2) {count ++;}if (arrs[i+1][j-1] == -2) {count ++;}if (arrs[i+1][j] == -2) {count ++;}if (arrs[i+1][j+1] == -2) {count ++;}if (arrs[i][j+1] == -2) {count ++;}arrs[i][j] = count;}}}else if (i == arrs.length -1){if (j == 0) {if (arrs[i][j] == -1) {int count = 0;if (arrs[i-1][j] == -2) {count ++;}if (arrs[i-1][j+1] == -2) {count ++;}if (arrs[i][j+1] == -2) {count ++;}arrs[i][j] = count;}}else if(j == arrs[i].length -1){if (arrs[i][j] == -1) {int count = 0;if (arrs[i][j-1] == -2) {count ++;}if (arrs[i-1][j-1] == -2) {count ++;}if (arrs[i-1][j] == -2) {count ++;}arrs[i][j] = count;}}else{if (arrs[i][j] == -1) {int count = 0;if (arrs[i][j-1] == -2) {count ++;}if (arrs[i-1][j-1] == -2) {count ++;}if (arrs[i-1][j] == -2) {count ++;}if (arrs[i-1][j+1] == -2) {count ++;}if (arrs[i][j+1] == -2) {count ++;}arrs[i][j] = count;}}}else {if (j == 0) {if (arrs[i][j] == -1) {int count = 0;if (arrs[i-1][j] == -2) {count ++;}if (arrs[i-1][j+1] == -2) {count ++;}if (arrs[i][j+1] == -2) {count ++;}if (arrs[i+1][j+1] == -2) {count ++;}if (arrs[i+1][j] == -2) {count ++;}arrs[i][j] = count;}}else if(j == arrs[i].length -1){if (arrs[i][j] == -1) {int count = 0;if (arrs[i-1][j] == -2) {count ++;}if (arrs[i-1][j-1] == -2) {count ++;}if (arrs[i][j-1] == -2) {count ++;}if (arrs[i+1][j-1] == -2) {count ++;}if (arrs[i+1][j] == -2) {count ++;}arrs[i][j] = count;}}else{if (arrs[i][j] == -1) {int count = 0;if (arrs[i][j-1] == -2) {count ++;}if (arrs[i-1][j-1] == -2) {count ++;}if (arrs[i-1][j] == -2) {count ++;}if (arrs[i-1][j+1] == -2) {count ++;}if (arrs[i][j+1] == -2) {count ++;}if (arrs[i+1][j+1] == -2) {count ++;}if (arrs[i+1][j] == -2) {count ++;}if (arrs[i+1][j-1] == -2) {count ++;}arrs[i][j] = count;}}}}}return arrs;}
