Reusability:可重用性,相同代码可以在多个应用的不同系统中作为组件使用 2、Object-Oriented Design Principles Modularity:模块化,将软件系统的不同组件划分为独立的功能单元 Abstraction:抽象,将一个复杂的系统提炼到最基本的部分(忽略无关信息) Encapsulation:封装,软件系统的不同组
Java的编程语言是面向对象的,采用这种语言进行编程称为面向对象编程(Object-Oriented Programming, OOP)。 1)抽象(abstract) 忽略一个主题中与当前目标无关的那些方面,以便更充分地注意与当前目标有关的方面。抽象并不打算了解全部问题,而只是选择其中的一部分,暂时不用关注细节。 例如:要设计一个学生成绩管理系统,那...
3.10 什么是抽象(Abstraction)和泛化(Generalization)? 抽象强调的其实是一种思想和概念,而不依赖于实现的细节。抽象最重要的功能是,可以通过抽象名字去引用对象从而达到隐藏对象中不相关细节的目的。抽象对于建立程序是十分重要的,它说明了一个对象是什么,这个对象能做些什么,而不是解释了这个对象怎么实现了这些内容的,...
C# is an object-oriented programming language. The four basic principles of object-oriented programming are: AbstractionModeling the relevant attributes and interactions of entities as classes to define an abstract representation of a system. EncapsulationHiding the internal state and functionality of an ...
Object-oriented programming is a programming paradigm[1], or classification, that organizes a group of data attributes with functions or methods into a unit, known as an object.第一句:面向对象编程是一种编程范式或分类。这句定义更像是描述了面向对象的封装特点。 面向对象编程把数据属性(大概是类中的...
If you are new to object-oriented programming languages, you will need to know a few basics before you can get started with code. The following Webopedia definitions will help you better understand object-oriented programming: Abstraction:The process of picking out (abstracting) common features of...

Four Pillars of Object-Oriented Programming (OOP) 1. Encapsulation 2. Inheritance 3. Polymorphism 4. Abstraction Let's start with class and object. What is a Class? A class is a blueprint or template for creating objects. It defines the structure and behavior of objects that belong to that...
In this guide you learned the fundamental principles of object-oriented programming. The concepts covered were encapsulation, abstraction, inheritance, and polymorphism. Applying these concepts helps to ensure that you are making the most of what the paradigm can do. Throughout this tutorial, the foc...
The object-oriented idea reflects in the actual environment: each object manages its own range of tasks, like the departments of a corporate organization. The three important characteristics of object-oriented programming are data abstraction, inheritance (type extension), and dynamic binding. ...
