wait notify

In Java, you can use the Wait () method and the Notify () method or the Notifyall () method to invoke the object objects to enable communication between threads. Calling the Wait () method in the thread will block notifications waiting for other

/*** Knowledge One:* Implement threading, there are two methods, one is to inherit the thread class, one is to implement the Runnable interface.* This article recommends the implementation of the Runnable interface method.* 1. Put the data that

Simulating consumer and subscriber patterns through threading:First of all, define a clerk: The clerk includes the purchase and sale method; Second, define a producer and producer to produce products for the clerk; Moreover, define a consumer who is

Thread Communication: Programs cannot control the rotation of threads, but there are mechanisms to ensure that threads work in harmony. Traditional thread CommunicationThe object class provides wait (), notify () and Notifyall () three methods to

Wait NotifyA few points to note:The wait and Notify/notifyall methods must be used in a synchronous code block, which is to lock the calling object first.When the thread executes wait (), it releases the current lock and then yields the CPU and

Recently in learning multi-threading, now to summarize it. The first thing to do is to look at the following nouns.(1) Wait: When the thread calls the Wait () method, the thread is currently in a blocking state and the lock is released and must be

Usually, coordination is required between multiple threads. For example, if displaythread of a browser that displays an image wants to execute the task of displaying the image, it must wait for the download thread downloadthread to download the

First, prefaceFor concurrent programming, in addition to the thread, the Wati and notify objects for object objects should also have a deep understanding of their usage, although there are not many knowledge points.II. basic knowledge of thread

1. Sleep ()Causes the current thread (that is, the thread that called the method) to suspend execution for a period of time, allowing other threads to continue executing, but it does not release the object lock. This means that if there is
