让它去继承Animal void wangWang(){ System.out.println(name + "喜欢汪汪叫！")...//让dog引用父类的成员方法 dog.eat(); dog.sleep(); //dog引用自己的的成员方法 dog.wangWang...(); //14.子类 this.wangWang(); //15.子类 } public void eat(){ System.out.println...(this.name + "子类正在吃饭"); } void wangWang(){ System.out.println(this.name + "子类喜欢汪汪叫！")...14. wangWang(); 输出：子类name子类喜欢汪汪叫！ 15. this.wangWang(); 输出：子类name子类喜欢汪汪叫！
dog类，继承animal的属性name class dog(animal): def shout(self): return 'wangwang...类，继承animal的属性name class wolf(animal): def shout(self): return 'wangwang
看下面一个例子： 上面通过一个关键字instanceof来判断，变量指向的对象是否是animal类的一个实例，下面new cat()，new dog()都是animal子类的对象，而输出了“dog say wangwang
