This article mainly introduces why concurrent programming is needed in java, which can be used for reference by interested friends. I hope you can learn a lot after reading this article.

Why do you need concurrent programming?

Concurrent programming helps us separate what to do and when to do it, which can significantly improve the throughput and organization of the application. Not only that, of course, there are often multiple reasons when it comes to concurrent programming. For example, business requirements, performance optimization needs, can simplify task scheduling, parallel programs have advantages in multi-core CPU.

Of course, there will be some precautions during this period, and there will be some misunderstandings about concurrent programming, for example, concurrency can not always improve performance, and it can significantly improve program performance when there is a lot of free time in CPU, but a large number of threads, frequent scheduling switching will reduce the performance of the system.

Therefore, we should objectively understand concurrent programming. For example, writing concurrent programs is bound to add extra overhead to the code; correct concurrency is very complex, even for simple problems; defects in concurrency are not easy to find because they are not easy to be rediscovered; concurrency often requires fundamental changes to the design strategy.

Thank you for reading this article carefully. I hope the article "Why concurrent programming in java" shared by the editor will be helpful to everyone. At the same time, I also hope that you will support us and pay attention to the industry information channel. More related knowledge is waiting for you to learn!
