Today, I will talk to you about the role of abstract classes, which may not be well understood by many people. in order to make you understand better, the editor has summarized the following content for you. I hope you can get something according to this article.

The use of abstract class is to provide an organizational mechanism for the project. Abstract class is often used to represent the abstract concepts derived from the analysis and design of the problem domain. It is the abstraction of a series of concrete concepts that look different but are essentially the same.

Abstract classes can provide an organizational mechanism for projects. An abstract class cannot be instantiated. Only a concrete (an instantiable class) inherits the interface of the abstract class and all its concrete properties.

Like most abstract classes, interfaces have abstract methods. However, you cannot include concrete methods or variables in an interface as you do in an abstract class.

Abstract class is often used to represent the abstract concepts derived from the analysis and design of the problem domain, which is the abstraction of a series of concrete concepts that look different but are essentially the same.

Classes that are usually decorated with abstract in programming statements are abstract classes. In C++, a class with pure virtual functions is called an abstract class, and it cannot generate objects; in java, a class with abstract methods is called an abstract class, and neither can it generate objects.

An abstract class is incomplete and can only be used as a base class. In the object-oriented method, abstract classes are mainly used for type hiding and acting as global variables.

After reading the above, do you have any further understanding of the role of abstract classes? If you want to know more knowledge or related content, please follow the industry information channel, thank you for your support.
