What are the advantages and disadvantages of Java process-oriented and object-oriented? most people do not understand the knowledge points of this article, so the editor summarizes the following content, detailed content, clear steps, and has a certain reference value. I hope you can get something after reading this article. Let's take a look at this "what are the advantages and disadvantages of Java process-oriented and object-oriented" article.

The advantage of using procedure-oriented is higher than object-oriented in performance, but because class calls need instantiation, it is expensive and resource-consuming; its disadvantage is that it is not as easy to maintain, reuse and expand as object-oriented.

Using the advantages of object-oriented: easy to maintain, easy to reuse, easy to expand, and because object-oriented has the characteristics of encapsulation, inheritance and polymorphism, we can design a low-coupling system, which makes the system more flexible and easier to maintain; its disadvantage: it is lower than process-oriented in performance.

Some remarkable features of object-oriented programming

The focus of programming is on data rather than process; programs are divided into so-called objects; data structures are designed to represent the characteristics of objects; functions, as operations on object data, are closely integrated with data structures; data is hidden and cannot be accessed by external functions; objects can communicate through functions New data and functions can be easily added when needed; follow a bottom-up (bottom-up) design approach in the programming process.

Object-oriented programming is a new concept in programming patterns, which may mean different contents to different people. We define object-oriented programming as "object-oriented programming is a method that provides a common independent memory space for data and functions. These data and functions can be used as templates to create copies of similar modules when needed. This programming method is called object-oriented programming."

As can be seen from the above definition, an object is considered to be a separate interval in computer memory, in which data is stored and a set of operations that can access the data. Because memory intervals are independent of each other, objects can be applied to many different programs without modification.

The above is the content of this article on "what are the advantages and disadvantages of Java process-oriented and object-oriented". I believe we all have a certain understanding. I hope the content shared by the editor will be helpful to you. If you want to know more related knowledge, please pay attention to the industry information channel.
