关于abstract中遇到的问题
所做东西的需求:
定义英雄类和Boss类，创建3个英雄对象，分别拿不同的武器，对敌人循环回合制攻击，输出战斗过程。
英雄类：特征：HP、MP、类型（枚举类型：弓箭手、法师、骑士）、武器 行为：攻击、防御
Boss类：特征：HP、攻击力、防御力 行为：攻击

在此应用设计的过程中遇到的问题为:当将一个类定义为抽象类的时候,抽象类中拥有的字段,在子类中千万不要进行定义,如果进行定义 那么子类所进行赋值的字段值将会覆盖父类其对应字段的值,这样会出现让你意想不到的错误,
当使用抽象类地时候 我们应该牢牢记住几点:
1.抽象类必须用abstract来修饰，抽象方法必须用abstract来修饰，抽象方法不能有方法体；
2.抽象类不能被实例化，无法用new来创建该类的实例；
3.包含抽象对象的类必须是抽象的。但是，可以定义一个不包含抽象方法的抽象类。在这种情况下，不能使用new操作符创建该类的实例。这种类是用来定义新子类的基类的。
4.含有抽象方法的类：直接在类中顶一个抽象的方法，或者继承了父类的抽象类，为完全实现，父类里面的方法，或者实现了一个接口，为全部实现里面的方法。
5.不能使用new操作符来从抽象类创建一个实例，但是抽象类可以作为一种数据类型。
