Understanding threads A process is divided into multiple independent execution streams, called threads Back to the previous example, a class should not only send and receive homework, but also do blackboard newspapers and clean up. If there is only the monitor, it is not only inefficient but also time-consuming. In order to complete the t ...

Thread pool Personal blog: www.xiaobeigua.icu 1.2} thread pool Thread pool is a common way to use threads effectively. A certain number of working threads can be created in the thread pool in advance. The client code directly submits tasks to the thread pool as an object. The thread pool caches these tasks in the work queue. The working t ...

2.1 what is thread communication and implementation steps There are two models of inter thread communication: shared memory and message passing In fact, thread communication is to realize the alternating work of threads and transmit information Specific steps of communication between threads: (involving upper, middle and lower parts) ...

There are three rules for how to make a class safe in a multithreaded environment. Let me tell you: 1. State variables are not shared between threads. 2. Change the state variable to immutable. 3. Use synchronization when accessing state variables. So you might ask, what are the state variables? Let's first look at a class without state vari ...
