What is Object Orientation? What is Object Oriented Object oriented explained

A programming approach that treats data types and functions as a whole is called object-oriented.

Data types and functions are the two basic elements of a program.

In the conventional management method, data types and functions are defined separately. The object-oriented concept is to place data types and related functions together for definition, thereby reducing the management cost and improving the reuse rate.

The first floor is also good.

In 20 words, it's really not easy to get an object-oriented approach. I'll try my best.

For example: man is a species, people are used to calling it "human", Jack Ma, you know, he is a specific person.

Object-oriented is the categorization of everything in the world, calling all people humans, pigs, dogs, cows, and sheep animals. These correspond to the classes in object-orientation, and the instantiation is a specific person, such as you, me, and so on.

Good luck.

Process-oriented is the process of attention.

Object-oriented is the purpose of attention.

Metaphor: A man drives to Xinjiang.

Facing the process, opening the door, inserting the key, starting the car, stepping on the clutch, gearing, throttle, playing direction, going on the high speed, getting off the high speed, stepping on the brakes, turning off the engine, opening the door, getting off.

Object-oriented: Encapsulate all of the car's operations into a "car class" and you tell the car "go! Go to Xinjiang", and then you will go to Xinjiang!

1. Object-oriented is a software development method. The concept and application of object-oriented has gone beyond programming and software development to include database systems, interactive interfaces, application structures, application platforms, distributed systems, network management structures, CAD technology, artificial intelligence, and other fields. Object-oriented is a method of understanding and abstracting the real world, which is a product of the development of computer programming technology to a certain stage.

2. Object-oriented is relative to process-oriented, object-oriented approach, which organizes relevant data and methods as a whole, and conducts system modeling from a higher level, which is closer to the natural operation mode of things.

The use of object orientation is very important in programming languages, and it took many years to acquire this technology in PHP languages. The advent of object-orientation was a great revolution in system development, and programming languages began to move from applications back to data. Object-oriented brings applications closer to the real world by shifting the focus of the programming process to the real thing being modeled.

The following computer training mainly introduces object-oriented for you.

1. What is object-orientation?

It's like you're the president of a company, and you're doing the job of assembling a set of computers. In other words, object-oriented is either an abstract execution or a work done by an employee. In detail, the president is not required to think about this issue.

IT training believes that the benefits are obvious, that a high-level management company can coordinate work without managing a high-level company, and that only a few employees who have implemented it will be in trouble.

2. Object-oriented characteristics.

1. Encapsulation. Hides the properties and implementation details of objects, exposes only the interface to the outside, and controls the access level of reading and modifying properties in the program; Combine abstract data and behaviors (or functions) into an organic whole, that is, organically combine data with the source of operating data to form a "class", where data and functions are members of the class.

2. Inheritance. Inheritance is the mechanism by which one or more classes are derived from a base class. A class that inherits from another class is called a subclass of that class.

This relationship is often compared to that of a father and a child. A child class inherits the properties of the parent class. These genus chaotic properties consist of properties and methods.

The North Jade Bird believes that the subclass can add new functions other than the parent class, so the subclass is also called the "" of the parent class.

3. Polymorphism. Polymorphism refers to the fact that OOP can redefine the nature or behavior of a class depending on the context in which it is used, or that many different implementations of an interface are polymorphic. Huilongguan Beida Jade Bird suggested that if different child objects are regarded as parent classes, the differences between different child objects can be shielded, and a common ** can be written, and general programming can be carried out to adapt to changes in requirements.
