This article introduces the relevant knowledge of "what is the principle of java multithreading". In the operation of actual cases, many people will encounter such a dilemma, so let the editor lead you to learn how to deal with these situations. I hope you can read it carefully and be able to achieve something!

The operating environment of this tutorial: windows7 system, java10 version, DELL G3 computer.

1. The principle of thread pool in multithreading

(1) determine whether all the core threads in the thread pool are executing the task, and if not (the core thread is idle, or the core thread is useless), create a new worker thread to execute the task. If all the core threads are performing the task, proceed to the next process.

(2) Thread pool determines whether the work queue is full. If the work queue is not full, store the newly submitted tasks in this work queue. If the work queue is full, proceed to the next process.

(3) determine whether the thread in the thread pool handles the working state, and if not, create a new worker thread to execute the task. If it is full, leave it to the saturation strategy to handle the task.

2. An example of multithreading

Public class Test implements Runnable {@ Override public void run () {try {Thread.sleep (10);} catch (InterruptedException e) {e.printStackTrace ();}} static ExecutorService service = newFixedThreadPool (3); public static void main (String [] args) {for (int iTuno)
