What can an instance of a class be called in an object-oriented method? This problem may be often seen in our daily study or work. I hope you can gain a lot from this question. The following is the reference content that the editor brings to you, let's take a look at it!

What is the name of an instance of a class in an object-oriented method?

In an object-oriented approach, an instance of a class is called an object.

Basic concept

The meaning of object refers to something specific, that is, something that can be seen and touched in real life. In object-oriented programming, an object refers to a component of a computer system. In object-oriented programming, an object contains two meanings, one of which is data and the other is action. Objects are a combination of data and actions. The object can not only operate, but also record the results of the operation in time.

A method is what an object can do, and it also has another name, called a function. A method is a definition function in a class, and its specific function is to describe the object.

Inheritance is simply a hierarchical model that can be reused. The upper layer of the hierarchical structure has generality, but the lower structure has particularity. In the process of inheritance, the class can inherit some methods and variables from the topmost part. Classes can be modified or added in addition to inheritance. Work efficiency can be effectively improved in this way. Here, for example, when class X inherits class Y, class X is a derived class, and class Y belongs to a base class. Inheritance is a process from general deduction to special process, which can reduce the redundant content of knowledge representation, and the maintenance and modification of knowledge base are very convenient. It is more advantageous to derive complex systems.

Related introduction:

Object-oriented (Object Oriented) is a software development method. Object-oriented concepts and applications have gone beyond programming and software development, and extended to fields such as database system, interactive interface, application structure, application platform, distributed system, network management structure, CAD technology, artificial intelligence and so on. Object-oriented is a method of understanding and abstracting the real world, and it is the product of the development of computer programming technology to a certain stage.

Compared with the process-oriented method, object-oriented method organizes the relevant data and methods as a whole, carries on the system modeling from a higher level, and is closer to the natural operation mode of things.
