Abstraction happens at class level design. It results in hiding the implementation details. Encapsulation is also known as “Information Hiding”. An example of encapsulation is marking the member variables private and providing getter and setter for these member variables....
Encapsulation and abstraction are two out of four pillars ofobject-oriented programming. Both principles help in designing a class so that the class can perform necessary functions, as well as, does not expose unwanted details to the other classes to avoid its misuse. In this post, we will un...

面向对象编程的四个主要特性如下: 抽象(Abstraction) 封装(Encapsulation) 继承(Inheritance) 多态(Polymorphism) 2.1 抽象 当我们将抽象与真实案例联系起来的时候,它将非常容易理解。例如,当我们驾驶一辆汽车时,我们不必关心汽车内部具体的工作原理,我们只需要关心如何通过汽车提供的接口对汽车进行操作即可,例如操纵方向盘、...
Object-oriented programming embodies three main characteristics.1. Encapsulation: data and operations on data encapsulated together, through abstraction, that is, from the concrete examples of common properties to form a general concept, such as the concept of class.2. inheritance: subclasses can ...

支持以下基本概念：多态、继承、封装、抽象、类、对象、实例、方法、重载Java is a object language. Supports the following basic concepts: polymorphism, inheritance, encapsulation, abstraction, classes, objects, instances, methods, overloading本节我们重点研究对象和类的概念。In this section, we focus on ...
Encapsulation: Encapsulation in Java is a mechanism of wrapping up the data and code together as a single unit. Abstraction: Abstraction is the methodology of hiding the implementation details from the user and only providing the functionality to the users. ...

The principles ofobject-oriented paradigm are centred around objects, classes, inheritance, polymorphism, encapsulation and abstraction. 72) Initially, what will the value ofan object reference be that is defined as an instance variable? The default valueof an object reference is `null`. ...
