Question

编写一个Dog类，可以保存宠物的名字和品种，体重，健康状况等信息。在Dog类中定义相应的方法，能够让宠物的主人得到宠物的名字，品种和体重以及健康状况信息。并定义相应的方法能够修改上述信息。
定义Man类，表示人，包含姓名，年龄，住址，电话等信息。在Man类中，做适当的定义，允许我们可以收养一只宠物。
定义Police类，同时修改Dog类，使得当警察发现一只流浪的Dog时，可以根据Dog对象的相应方法，获得狗狗主人的姓名，地址信息。

//以下程序经过了测试，并且在逻辑上正确。

class Dog{
protected String name; //名字
protected String breed; //品种
protected double weight; //体重
protected String health; //健康状况
protected Man host; //主人
