This article mainly talks about "what is the method of Java daemon thread". Interested friends may wish to have a look at it. The method introduced in this paper is simple, fast and practical. Let's let the editor take you to learn "what is the method of Java daemon thread"?

Define

What is a daemon thread? Corresponding to the daemon thread is the user thread, the daemon thread is the daemon user thread, when the user thread is finished, the daemon thread will end. That is, the daemon thread must be accompanied by the user thread. If there is only one daemon thread in an application and there is no user thread, the daemon thread will exit naturally.

Application

Here is a simple application of the daemon thread

To create a simple thread, setting daemon to true means setting it to be a daemon thread, where the main thread exits after blocking any system input by the user, and the daemon thread guards the main thread. The daemon thread prints the value of I every second until the main thread exits by typing any character, and the main thread exits after the daemon thread exits.

Run the above program, enter any character: n, and the daemon thread exits and the program stops printing.

Be careful

The setDaemon method must be set before the thread start method starts, or an exception will be thrown.

At this point, I believe you have a deeper understanding of "what is the method of Java daemon thread". 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!
