Last time, we first understood the concepts of threading, process and multithreading, and learned to implement multithreading by inheriting the Thread class This section will help you understand

CountDownLatch is a synchronization tool class, which is used to coordinate the synchronization between multiple threads or talk about the communication between threads (rather than being used as mutual exclusion).
CountDownLatch enables a thread to wait for other threads to complete their work before continuing execution ...

Thread safe - ThreadLocal
Shared resources are accessed by multiple threads at the same time, which may be unsafe. Thread safety has always been a very important thing. Failure to properly handle the problem of thread safety may lead to errors and even difficult to reproduce and check.
Common solutions include defining immutable vari ...

Times make heroes: intelligence and diligence are the preconditions for success. There are many smart and diligent people in the world. What is really important is to follow the trend!
A large number of articles on the Internet say that the synchronized lock in Java is a heavyweight lock. Because the system call is used, it will ...

1, What is network programming The so-called network programming is to realize the communication between hosts in the network
1. In the whole communication process, there are generally two kinds of endpoints: server and client 2. There are two modes of program development around the server and client: C/S structure (two sets of programs nee ...

Two modules commonly used in Python 3 threads are:
_ thread (obsolete)Threading (recommended)
Python 3 uses two standard libraries_ thread and threading provide support for threads.
_ thread provides low-level, original threads and a simple lock. Compared with threading module, its function is still relatively limited. ...

This article continues to explore JUC. The main points are
Callable is one of the three ways to implement threads in java, and it is also the most commonly used interface to implement threads in enterprises. Let's first look at how to use callable, and then discuss something else
