请帮忙用数据结构(java版)的知识解决这道迷宫问题的程序代码。

我这是用c写的。你可以看看,希望能帮助到你。

急需一java高手帮忙写一迷宫程序

给你代码,你给出的那两个类,不能满足,我的需要,我就没有使用。

你看一下吧。

java老鼠迷宫代码难吗

非常难。思路:

1、设老鼠的行进路线都是优先选择下-右-上-左。

2、设老鼠很聪明,走过的路线走撒泡尿,表示鼠大爷到此一游,我们可以把数组的值改为3,表示走过,但走不通。

3、这是一个int[8][8]的二位数组,那么开始位置下标是1,1,结束位置是6,6。行和列分别用、j表示。

4、实际路线我们可以设置2表示,我们可以使用递归,让老鼠不断测试路线。

5、最后打印数组,看老鼠的实际路线。
