求用java语言寻找走出迷宫路线的算法首先给定一个初始坐标迷宫Java算法代码，然后构建一个容器保存坐标值迷宫Java算法代码，之后进行迭代 ， 横坐标 1，或者纵坐标 1，这个顺寻自己定义（四个方向），经过迷宫Java算法代码的“路径”保存在那个容器中，如果遇到死角，以此往回迭代，在容器中将遇到死角的那个坐标删除 。最后找到自己定义的那个迷宫出口坐标 。
用java语言控制小机器人走迷宫的算法?我昨天刚写了个走迷宫的界面(一个初始小球，一个目标小球，随机在界面种生成障碍(迷宫图)，然后初始小球移动到目标小球那)，不知道是否跟你的想法一样 。用的是回溯法(目前我只知道这个算法走迷宫)，你可以查下 。PS:我电脑没联网不能把代码给你…QQ254774042 。
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 。你可以看看迷宫Java算法代码 ， 希望能帮助到你 。
