This article introduces the relevant knowledge of "how to use Exchanger in java". In the operation process of actual cases, many people will encounter such difficulties. Next, let Xiaobian lead you to learn how to deal with these situations! I hope you can read carefully and learn something!

Exchangers can be used to exchange data between threads. Threads can call the exchange() method in Exchanger to exchange data. Data is exchanged only if both threads call the exchange() method, and if only one thread executes the exchange() method, the current thread waits until another thread executes the exchange() method.

Let's analyze the output. When the thread starts, the loop is executed first. When the loop of thread 1 is executed, the current thread is suspended instead of directly executing the following statements. The reason is that we call the exchange() method. When we call the exchange() method, we must wait for other threads to call the exchange() method. Otherwise, the current thread blocks, that is, we will wait all the time. When thread 2 finishes executing the loop call exchange() method, thread 1 resumes execution and obtains the information of thread 2 and outputs it. The same is true for thread 2. In other words, using the exchange() method in Exchanger allows threads to communicate and exchange information with each other. In daily development, you can use the Exchanger class exchange() method to handle data validation work.
