JAVA迷宫问题，怎么输出所走路径的坐标

在Way函数的if(Maza[Loci][Locj]==0) 语句里面Maza[Loci][Locj]=2;前面加一句

System.out.println("The Maza route is ("+Loci+","+Locj+")");就打印出程序所走路径的坐标了.

求大佬讲解一下这段java代码

//直译了哦,只有片面的代码,只能靠推测,其他你自己补充下:

//这个主要是对一个图像控件设置了键盘侦听事件,按下键盘时候对其进行坐标移位操作

//必须知道:ImageView图像控件,显示图片或者其他;num是一个二位数组,这里可以理解成矩阵地图;

public void control(int[][] num, ImageView iv) {

//对控件设置键盘侦听,

iv.setOnKeyPressed(e - {

//设置一个变量,从下面使用看,这个应该是一个图像步进单位

int m = 30;

//以下为:try catch封装的键盘四向按键判断

try {

//字面意义推测:row应该是行,col应该是列,这是用二维数组画了一个矩阵地图,0不能走,1可以走;

//如果键盘按下的键是s,并且"行+1"小于地图中的行的个数,并且:地图[row+1行][col列]的值不等于0

if (e.getCode() == KeyCode.S  row + 1  num.length  num[row + 1][col] != 0) {

//就设置图像y坐标(在原有坐标的基础上进行一个步进单位的叠加)

iv.setY(iv.getY() + m);

//行递增1:row=row+1;

row++;

}

//其实这里与下面与上面都是一个道理,仅仅判断的条件与按键不同罢了

if (e.getCode() == KeyCode.W  row - 1 = 0  num[row - 1][col] != 0) {

iv.setY(iv.getY() - m);

   //行递减1

row--;

  }

//同上

if (e.getCode() == KeyCode.A  col - 1 = 0  num[row][col - 1] != 0) {

iv.setX(iv.getX() - m);

//列递减1

col--;

}

//同上

if (e.getCode() == KeyCode.D  col + 1  num[0].length  num[row][col + 1] != 0) {

iv.setX(iv.getX() + m);

//列递增1

col++;

  }

}catch (Exception n) {}

//如果行等于地图"行"的最大的索引值,并且列等于第一行数组的最大索引值

if (row == num.length - 1  col == num[0].length - 1) {

//就调用win函数;

win();

}

});

}

急！！求用Java实现牛郎织女迷宫问题的代码

不是不想帮你。像这种问题 需要去专业性网站去问。并且 分数一定要高。

比如 这个论坛里 高手都往这里走。 再高高的高手只会在自己的领域。不会上网上论坛。嘿嘿
