This article mainly introduces "the principle analysis of Java concurrent programming". In the daily operation, I believe that many people have doubts about the principle analysis of Java concurrent programming. The editor consulted all kinds of materials and sorted out simple and easy-to-use operation methods. I hope it will be helpful for you to answer the doubts of "principle analysis of Java concurrent programming". Next, please follow the editor to study!

Why learn Java concurrent programming?

1. The need for employment:

Nowadays, the hardware technology that Internet technology relies on has been very advanced and mature. Generally speaking, our current services are deployed in a relatively high-configuration hardware environment, so multi-core processors are inevitable. Nowadays, Java concurrent programming has become a required test for interviews in famous enterprises, so high concurrency scenarios are a necessary core foundation for Java practitioners.

2. Its own advantages:

(1) Java concurrent programming can improve performance. For example, the utilization efficiency of CPU can be improved by improving the utilization of multi-core CPU and the utilization of CPU when accessing I Zero. It can also reduce the response time of the system, such as using multithreading to avoid the problem of long response time, users can take turns to use CPU resources, users may not always occupy the system, but regardless of the order in which they visit the server, each user can get a quick response from the user.

(2) improve the fault tolerance of the system A thread can run independently without interference from other threads. If Bug appears in the code of a thread, the thread may throw an exception and exit. At this time, other threads can continue to execute without any impact, so as not to cause the whole system to crash.

(3) it is convenient to write code-simulation. Although Java concurrent programming is not perfect, the pros and cons of using concurrency should be weighed against the actual situation. However, with the growth of the number of CPU core and system users, multithreading is more and more widely used. In most cases, the disadvantages of multithreading are negligible in the face of its advantages.

Introduction to Java concurrent programming principles parsing tutorial:

This course is located in a most complete and in-depth concurrent programming system, which covers thread foundation, atomic operation, development tool class, and is a necessary concurrent programming system manual. This course is designed to explain all concepts in the most popular and easy-to-understand way, analyzing complex concepts and details from simple to deep, so that students know what they are and why.

Highlights of the Java concurrent programming principles parsing tutorial:

1. The learning content is comprehensive. The three basic courses of concurrent programming cover three knowledge modules: thread foundation, atomic operation CAS and concurrent tools, which can help students cope with the interview knowledge successfully. Content explanation is thorough from application to source code (from Java to underlying C/CPP), from case analysis to design ideas, algorithms and design patterns, all-round explanation will never dabble.

2. the time and place of study is free. Along with learning, as long as you can access the Internet, you can learn at any time without waiting, making everyone's learning more flexible and efficient.

3. All kinds of learning resources are complete. Open source provides all the course source code to ensure that practical exercises are more efficient. Matching materials are highly compatible with supporting handouts, courseware, testing environment and other materials to ensure students' all-round understanding of knowledge and skills.

Learning gains from the Java concurrent programming principles parsing tutorial:

1. Understand the basic concepts related to concurrency and be able to perform basic threading operations

2. Understand the concept and implementation principle of atomic operation, and be able to correctly use the atomic operation class under concurrent package.

3. Be able to use them correctly according to the characteristics of common concurrent tool classes.

At this point, the study of "the principle of Java concurrent programming" is over. I hope to be able to solve everyone's doubts. The collocation of theory and practice can better help you learn, go and try it! If you want to continue to learn more related knowledge, please continue to follow the website, the editor will continue to work hard to bring you more practical articles!
