四大特性 封装(Encapsulation) 抽象(Abstraction) 继承(Inheritance) 多态(Polymorphism) 封装(Encapsulation) 封装也叫作信息隐藏或者数据访问保护。类通过暴露有限的访问接口,授权外部仅能通过类提供的方式(或者叫函数)来访问内部信息或者数据。 下面这段代码是金融系统中一个简化版的虚拟钱包的代码实现。在金融系统中,我...
Inheritance, polymorphism, and encapsulation comprise the three central characteristics of object-oriented (OO) programming. Inheritance allows you to create class hierarchies, where a base class gives its behavior and attributes to a derived class. You are then free to modify or extend its ...
In this example, both Circle and Square classes implement the IShape interface, providing their own implementation of the Draw method. This allows for polymorphic behavior when interacting with objects through the IShape interface. Conclusion Encapsulation, inheritance, and polymorphism are fundamental con...
Java is an object-oriented language. Foundations of any object oriented language are laid on three pillars: Polymorphism, Inheritance and Encapsulation. Inheritance refers to the ability of a class to extend another class without having to rewrite the code in the parent class. Inheritance fosters co...
Polymorphism is often referred to as the third pillar of object-oriented programming, after encapsulation and inheritance. Polymorphism is a Greek word that means "many-shaped" and it has two distinct aspects: At run time, objects of a derived class may be treated as objects of a base class...

The three main features of object-oriented programming are - encapsulation, inheritance and polymorphism. We have seen the first two, now let us see what is polymorphism. The meaning of the word polymorphism is the ability to take many forms. In programming, this means the ability of code to...

operates on objects of different types without needing to know their specific implementations. This leads to shorter, more concise code that is easier to understand and maintain. Polymorphism also improves the readability of code by allowing for better organization and encapsulation of related behaviors...
