This article mainly explains "what are the Java multithreading application methods". The content of the article is simple and clear, and it is easy to learn and understand. Please follow the editor's train of thought to study and learn what Java multithreading application methods have.

The following methods are often used in Java multithreaded programs: run (), start (), wait (), sleep (), notify (), notifyAll (), yield (), join (), and an important keyword synchronized. These methods are explained below:

1. Run () and start ()

Both of these methods should be familiar. Put the code that needs to be processed in parallel in the run () method, and the thread started by the start () method will automatically call the run () method, which is specified by Java's memory mechanism. And the run () method must have public access and the return value type is void.

Second, the keyword Synchronized

This keyword is used to protect shared data, of course, as long as it is clear which data is shared. Each object has a lock flag, and when a thread accesses the object, the data modified by Synchronized will be "locked" to prevent other threads from accessing it. After the current thread has accessed this part of the data, release the lock flag, and other threads can access it.

Public ThreadTest implements Runnable {public synchronized void run () {for (int iTuno)
