This article is to share with you about the meaning of the development of java. The editor thinks it is very practical, so share it with you as a reference and follow the editor to have a look.

Java is an object-oriented programming language, which not only absorbs the advantages of C++ language, but also abandons the concepts of multi-inheritance and pointers which are difficult to understand in C++, so Java language has two characteristics: powerful and easy to use. As the representative of static object-oriented programming language, Java language perfectly implements the object-oriented theory and allows programmers to carry out complex programming in an elegant way of thinking.

What does java mean?

Java has the characteristics of simplicity, object-oriented, distributed, robust, security, platform independence and portability, multithreading, dynamic and so on. Java can write desktop applications, Web applications, distributed systems, embedded system applications and so on.

What does the development of java mean?

In the 1990s, a single-chip computer system appeared in the hardware field. as soon as this low-cost system appeared, it immediately attracted the attention of people in the field of automatic control. because using it can greatly improve the intelligence of consumer electronic products (such as TV set-top boxes, bread ovens, mobile phones, etc.). In order to gain a head start in the market, Sun set up a project team called Green in 1991. Patrick, James Gosling, Mike Sherlindane and several other engineers formed a working group to research and develop new technologies in a small studio on Sand Hill Road in Menlo Park, California, specializing in embedded applications of computers in home appliances.

Because of the advantages of C++, the researchers of the project team first considered using C++ to write the program. But for the monolithic system with extremely poor hardware resources, the C++ program is too complex and huge. In addition, due to the variety of embedded processor chips used in consumer electronic products, how to make the program run across platforms is also a difficult problem. In order to solve the difficulties, they first focused on the development of the language, assumed a hardware platform architecture with simple structure and met the needs of embedded applications, and formulated corresponding specifications for it. among them, the binary machine code instruction system of this hardware platform (that is, the instruction system that later became "bytecode") is defined, after the successful development of the language. Semiconductor chip manufacturers can develop and produce such hardware platforms. For the design of the new language, the research and development personnel of Sun company did not develop a new language, but reformed C++ according to the requirements of embedded software, removed some impractical components left in C++ and affected security, and combined with the real-time requirements of embedded system, developed an object-oriented language called Oak.
