Threads have a life cycle that contains 7 states, namely, birth status, ready state, running state, waiting state, hibernation state, blocking state, and dead busy state.1, the sleep of the threadFor example, create a Sleepmethodtest class in the

Introduction:The producer-consumer model of the operating system curriculum can be said to be the best example of learning concurrency. It is important to note that Java does not support processes and only supports multithreading. This article will

There are several ways to create threads:1.通过继承Thread类来创建一个线程：/** * Step 1: Define a subclass that inherits the thread class * Step 2: Construct an object of subclass * Step 3: Start Thread: * */public class Threadtest{public static void Main

Brief introduction: 1. To understand multi-threading, first we need to understand the processes and threads. So what is a process? A process is a running program that allocates memory so that an application can run as a process. So what's the
