This article mainly explains "how to use ReentrantLock class in jdk". Interested friends may wish to have a look at it. The method introduced in this paper is simple, fast and practical. Now let the editor take you to learn "how to use the ReentrantLock class in jdk"!

We know that in multithreaded development, we can use the synchronized synchronization keyword to solve the thread safety problem. In other articles, we have made the corresponding introduction, from today we introduce other methods to solve the thread safety problem, that is to use ReentrantLock. ReentrantLock, which has been added since JDK1.5, is more powerful and flexible in extension than the synchronized synchronization keyword. Let's take a look at its simple use first.

We see that the output is executed synchronously, which means that as soon as the thread acquires the lock of the object during execution, the lock is released only when it is finished, and then other threads can re-acquire the lock and execute.

At this point, I believe you have a deeper understanding of "the use of ReentrantLock classes in jdk". You might as well do it in practice. Here is the website, more related content can enter the relevant channels to inquire, follow us, continue to learn!
