This article mainly explains "how to understand the object-oriented concept of Java". The content of the explanation is simple and clear, and it is easy to learn and understand. Please follow the editor's train of thought to study and learn "how to understand the object-oriented concept of Java".

As the core foundation of building a programming language, Java has been favored by more and more people. While people are full of yearning for Java, they are more and more interested in the knowledge points of Java objects. What exactly does object-oriented mean? Let's start with the concept. Object-oriented is the most popular software design and development method. The biggest feature of Java itself is that it is an object-oriented programming language, and the two core elements of object-oriented are classes and objects. As we all know, almost all program development is based on object-oriented, which includes three main features, namely, encapsulation, inheritance and polymorphism.

First of all, let's talk briefly about encapsulation. Encapsulation is an important principle that object-oriented methods should follow. The seal has two meanings: one is to regard the properties and methods of the object members as an inseparable whole, encapsulating the two in an independent unit, and the other is to hide the information that does not need to be known to the outside world. some object properties and methods allow outside users to know, but there are also some methods and attributes that are not allowed to be known to the outside world, or are only allowed to use the functions of the object.

Secondly, inheritance is an important concept in object-oriented methods and an important means to improve the efficiency of software development. Inherit classes that reflect the general characteristics of things, and then derive classes that reflect things on the basis of them. For example, there are some animal classes, which describe the basic properties and methods of animals. The inheritance mechanism in object-oriented programming greatly enhances the reuse of program code, improves the efficiency of software development, reduces the possibility of program errors, and of course provides convenience for program modification.

Finally, it is polymorphism, which is another important feature of programming-oriented. Polymorphism refers to the phenomenon of duplicate names among programmers. Java language contains two forms of polymorphism: method overloading and object polymorphism.

Thank you for your reading, the above is the content of "how to understand Java object-oriented concept". After the study of this article, I believe you have a deeper understanding of how to understand Java object-oriented concept, and the specific use needs to be verified in practice. Here is, the editor will push for you more related knowledge points of the article, welcome to follow!
