3.1继承性的概念 继承(extends)是创建新类的一种机制, 目的是专门使用和修改先有类的行为. 原有类称为超类(super class), 基类(base class)或父类. 新类称为子类或派生类. 通过继承创建类时, 所创建的类将继承其基类所有的属性和方法, 派生类也可以重新定义任何这些属性和方法, 并添加自己的新属性和方法 3...

继承通过使用关键字extends来实现,子类继承父类的特性并可以添加自己的功能。 继承提供了代码重用和扩展的机制,实现了类之间的层次结构。 8.多态(Polymorphism): 多态是面向对象编程的一个重要概念,允许使用一个对象以多种不同的方式呈现。 多态通过使用父类类型的引用变量来引用子类的对象来实现。 多态提供了灵活性和...
