3.《模拟动物园》

请根据以上场景进行类建模（画类图）和实现相应代代码。
场景如下：
1）假设有一个动物园（Zoo类来实现），动物园名称由用户定义，动物园有好多动物（Animal类）；
2）动物园里可以增加动物public void add(Animal animal ) ，和移除动物remove(Animal animal )
3）可以统计动物园中动物园的数量public int count()
4）可以列出动物园里的所有动物。public void listAnimals() ，显示动物的类名和动物名称
5）有多种多样的动物，每只动物都有个名称。动物都会发出叫声 wow()
6）考虑时间关系，假设只有两种动物，分别是老虎（Tiger类）和蛇(Snake类)。老虎和蛇的叫声分别是roaring 和hissing
7)有一个管理员（Manager）来管理动物园。他可以放动物到动物园，也可以从动物园里移除动物。当放入动物的时候，动物会发出自己的声音。叫声的格式：动物名 is 叫声！
8）假设有个Game类，来完成模拟管理园放动物到动物园和从动物园移除动物的工程。参考代码Game中的main方法。

输入要求
多组输入。
格式：
动物园名称管理员名称老虎名1 老虎名2 蛇名1 蛇名2（名字之间不允许空格）

输出要求
参考Game中的Main方法。
输入

ZooKeeper Tom
LELE FANFAN XVXV SS

输出

LELE is roaring!
FANFAN is roaring!
XVXV is hissing!
SS is hissing!
There are 4 Animals in Zoo ZooKeeper
Tiger:LELE
Tiger:FANFAN
Snake:XVXV
Snake:SS
