The last tool in the lock is introduced from this section: read-write Lock (Readwritelock).Reentrantlock implements a standard mutex, which is the notion that only one thread can hold a lock at a time, or the so-called exclusive lock. This feature

Before learning about the variable scope of JavaScript, we should make a few clear points: The variable scope of JavaScript is based on its unique scope chain. JavaScript does not have block-level scopes. Xianning Center Primary School

Deadlock and Activity degreeMany of the concurrency features and tools are discussed earlier, but most are related to locks. We use locks to ensure thread safety, but this can also cause problems. Lock sequence Deadlock (lock-ordering

Originally wanted to be more comprehensive and in-depth talk about Concurrenthashmap, found online there are a lot of hashmap and concurrenthashmap analysis of the article, so this section as far as possible to analyze the details, less theoretical

The synchronization point of the thread that can pair and swap elements in pairs. Each thread renders a method on the entry to the exchange method, matches the partner thread, and receives the object of its partner when it returns. Exchanger may be

and the tool class introduced by the contract many methods throw a certain exception that describes the exceptions that occur when the task is executed in the thread pool, and usually these exceptions require the application to capture and

This section describes the last tool of the queue and is the most powerful tool. You can see the feature of this tool from the name: bidirectional concurrent blocking queue. The so-called bidirectional means that can be manipulated from the head and

Start with a relatively simple atomic (Java.util.concurrent is a queue-based contract and the queue, in many cases, uses the atomic operation, so begin here first). In many cases we just need a simple, efficient, thread-safe increment-decrement

In this section, we begin to discuss array atomic operations and some other atomic operations.Atomicintegerarray/atomiclongarray/atomicreferencearray 's API is similar, select a representative atomicintegerarray to describe these issues.int get (int

Before we understand the J.U.C principle and the locking mechanism, we introduce the core and most complex basic class of the J.U.C framework:Java.util.concurrent.locks.AbstractQueuedSynchronizer.AQSAbstractqueuedsynchronizer, referred to as AQS, is

Original linkIn the first article, I introduced the basics of Rxjava. In the second article, I showed you the power of the operator. But you may still not be persuaded. In this article, I'm going to show you some of the other benefits of Rxjava,

What are the benefits of understanding the garbage collection mechanism (GC) for Java developers? The first thing you can do is to satisfy your curiosity as a software engineer, and second, to learn more about how GC works can help you write better

Before we introduce the non-MFC DLLs, this section will describe in detail the creation and use of MFC rules DLLs.In addition, since the beginning of this article, I have received some e-mails from readers. Some readers put forward some questions,
