Inheritance&&polymorphism 层次概念是计算机的重要概念.通过继承(inheritance)的机制可对类(class)分层,提供类型/子类型的关系.C++通过类派生(class derivation)机制来支持继承.继承是使子类可以使用父类的成员,达到代码的复用和类的抽象    被继承的类型称为基类(base class)或超类(superclass),新产生的类为派生类(derived class)或子类(subclass).基类和派生类的集合称作类继承层次结构(h…

1.封装 把数据和方法包装进类中,以及具体实现的隐藏,常共同被称作是是封装.其结果是一个同时带有特征和行为的数据类型.所谓具体实现的隐藏是通过访问权限控制实现的.JAVA 子类重写继承的方法时,不可以降低方法的访问权限,子类继承父类的访问修饰符要比父类的更大,也就是更加开放,假如我父类是protected修饰的,其子类只能是protected或者public,绝对不能是friendly(默认的访问范围)或者private,当然使用private就不是继承了.还要注意的是,继承当中子类抛出的异常必…

Brief 从Mix-In模式到Mixin模式,中文常用翻译为“混入/织入模式”.单纯从名字上看不到多少端倪,而通过采用Mixin模式的jQuery.extend我们是否可以认为Mixin模式就是深拷贝的代名词呢? 本文试图从继承机制入手对Mixin模式进行剖析,若有纰漏请大家指正,谢谢. The Fact of Inheritance     首先让我们一起探讨一下继承机制吧.作为OOP的三个重要特性(Inheritance,Polymorphism,and Encapsulation)之一,…

JVM & Bytecode Has-a or Is-a relationship(inheritance or composition) 如果想利用新类内部一个现有类的特性,而不想使用它的接口,通常应选择合成.也就是说,我们可嵌入一个对象,使自己能用它实现新类的特性.但新类的用户会看到我们已定义的接口,而不是来自嵌入对象的接口.考虑到这种效果,我们需在新类里嵌入现有类的private对象.有些时候,我们想让类用户直接访问新类的合成.也就是说,需要将成员对象的属性变为public.成员对象会将自…

JVM & Bytecode Abstract & Object Object in Java (1) 所有东西都是对象object.可将对象想象成一种新型变量:它保存着数据,但可要求它对自身进行操作self-operation(this pointer is always as parameter pssing to function called on object).理论上讲,可从要解决的问题身上提出所有概念性的组件,然后在程序中将其表达为一个对象. (2) 程序是一大堆对象的组合c…
