## 动物换位（含有源码） ##

这个是Java课程设计上面的一个小游戏，动物换位，这里给出这个源代码，供大家一起学习。

项目的题目：  
设计GUI界面的动物换位游戏，游戏结果是让左、右两组动物交换位置。具 体要求如下：  
①在水平排列的7个位置上左、右各有3个类型相同的动物，中间的位置上没有动物。左边动物将其右侧视为自己的前进方向，右边动物将其左侧视为自己的前进方向。  
②单击一个动物，如果该动物的前方位置上没有动物，该动物就跳跃到该位置上，如果该动物的前方位置上有其他动物，但相隔一位的位置上没有其他动物，该动物就越过自己前面的动物跳跃至该隔位上，其他情形下该动物不能跳跃（跳跃时不能越过两个位置)。  
③左面的动物只能向右方跳跃，右面的动物只能向左方跳跃。  
①单击“撒销”按钮撤销上一次移动的动物，单击“重新开始”按钮可重新开始游戏
