JAVA基础-练习-多态

练习-多态

题目：
immortal是不朽的，不死的意思

mortal就是终有一死的，凡人的意思

1. 设计一个接口
   接口叫做Mortal,其中有一个方法叫做die

2. 实现接口
   分别让ADHero,APHero,ADAPHero这三个类，实现Mortal接口，不同的类实现die方法的时候，都打印出不一样的字符串

3. 为Hero类，添加一个方法,在这个方法中调用 m的die方法。

   public void kill(Mortal m)

4. 在主方法中
   首先实例化出一个Hero对象:盖伦
   然后实例化出3个对象，分别是ADHero,APHero,ADAPHero的实例
   然后让盖伦 kill 这3个对象

​
