java三大特性之多态的认识，以及多态的实际应用（二）

多态的实际作用：将不同子类对象统一当作父类对象，屏蔽了不同子类之间的差异。使用多态的好处：应用程序不必为每一个派生类编写功能调用，只需要对抽象基类进行处理即可。大大提高程序的可复用性。//继承派生类的功能可以被基类的方法或引用变量所调用，这叫向后兼容，可以提高可扩充性和可维护性。 //多态的真正作用...

java三大特性之多态的认识，以及多态的实际应用（一）

首先，什么是多态？我们应该从什么角度来理解多态？其实，我们不妨把多态理解成一种事物的多种存在形态，比如，猫和狗都属于动物的子类，可以想象成为动物，而动物又可以变成猫和狗。多态是将子类对象当作__父类__对象来看待，也就是子类对象可以放入父类中引用。为了充分理解多态&#x...
