java multithreading tutorial

Multithreading is a concept proposed by Java, so what is a thread? Here are a few names that listen to something very similar: programs, threads, processes.Program: A series of files stored on disk, including executables and non-executable files.Process: In memory, each program will open a process.Thread: The thread is the smallest execution unit of the process, and the thread is in the register, each threa

Jakob Jenkov Translator:simon-sz proofreading: Fang Feihttp://tutorials.jenkov.com/ java-concurrency/index.html In the past single-CPU era, single-tasking can only execute a single program at a point in time. Later in the multitasking phase, computers can perform multitasking or multiple processes in parallel at the same point in time. Although it is not really the "same point in time", but multiple tasks or processes share a CPU, and the operating

Before the habit of writing notes, now slowly found in time to sum up is how important, hehe. Although only sophomore, but also near graduation, to refuel.This article is mainly about Java multithreading, mainly driven by examples. Because of the multithreading of the books and articles have a lot of, so I am also embarrassed to say, hehe, you can go to reference

with the platform, and can be run on a variety of platforms. Background development, is an efficient, practical programming method. People can only see the pattern, the results of calculations, etc. in front of the screen. In fact, the operating system often in the background to schedule some events, the flow of management programs. For example, the stack in the operating system, resource allocation and management between threads, memory creation, access, management, etc. . Here are a few more

Here, the most important questions are listed from the interview point of view, but you should still have a solid grasp of the basics of

There are two ways to implement multithreading in Java: Inherit the thread class and implement the Runnable interface . 1. Inherit the thread class, overriding the parent class run () method public class Thread1 extends Thread {public void run () {for (int i = 0; i The run () method is just a normal method, which is sequential, that is, Th1.run () execution completes before Th

algorithm, so that users look at the same time, actually from the CPU operating level is not true at the same time. Concurrency often has common resources in the scene, then for this common resources often create bottlenecks, we will use TPS or QPS to reflect the processing capacity of the system. Concurrency and parallel thread safety: often used to depict a piece of code. In the case of concurrency, the code is used in multithreading, and the sche
