根据需求完成代码:1.定义狗类
属性
行为:
2.定义猫类
属性:
行为:
年龄，颜色
eat(String something)(something表示吃的东西)看家lookHome方法(无参数)
年龄，颜色
eat(String something)方法(something表示吃的东西)逮老鼠catchMouse方法(无参数)
3.定义Person类//饲养员
属性姓名，年龄行为:
keepPet(Dog dog,String something)方法功能:喂养宠物狗，something表示喂养的东西
行为:
keepPet(Cat cat,String something)方法功能:喂养宠物猫，something表示喂养的东西生成空参有参构造，set和get方法4.定义测试类(完成以下打印效果):keepPet(Dog dog,String somethind)方法打印内容如下:年龄为30岁的老王养了一只黑颜色的2岁的狗2岁的黑颜色的狗两只前腿死死的抱住骨头猛吃keepPet(Cat cat,String somethind)方法打印内容如下:年龄为25岁的老李养了一只灰颜色的3岁的猫3岁的灰颜色的猫眯着眼睛侧着头吃鱼
5.思考:
1.Dog和Cat都是Animal的子类，以上案例中针对不同的动物，定义了不同的keepPet方法，过于繁琐，能否简化，并体会简化后的好处?
2.Doq和Cat虽然都是Animal的子类，但是都有其特有方法，能否想办法在keepPet中调用特有方法?
