迷宫问题(利用到了小小的递归)

package A;

public class JosePhu {
public static void main(String[] args) {
ArrayStack arrayStack=new ArrayStack();
int[][] map=new int[8][7];
for(int i=0;i<7;i++){
map[0][i]=1;
map[7][i]=1;
}
for (int i = 0; i < 8; i++) {
map[i][0]=1;
map[i][6]=1;
}
map[3][1]=1;
map[3][2]=1;
/*map[1][2]=1;
map[2][2]=1;*/

System.out.println("地图的情况");
//原理数组你不去赋值的话,他的默认值是0
for (int i = 0; i < 8; i++) {
for (int j = 0; j < 7; j++) {
System.out.print(map[i][j]+" ");
}
System.out.println();
}
arrayStack.setWay(map,1,1);

System.out.println("小球走过,并标识过的 地图的情况");
for (int i = 0; i < 8; i++) {
for (int j = 0; j < 7; j++) {
System.out.print(map[i][j]+" ");
}
System.out.println();
}
}
}

package A;

public class ArrayStack {
public boolean setWay(int[][] map,int i,int j){
if (map[6][5]==2){
return true;
}else {
if (map[i][j]==0){
map[i][j]=2;
if (setWay(map,i+1,j)){//下移
return true;

return true;
