Foreword

Hello everyone, I am a great programmer.

There is less than a month left for the gold nine silver ten. In this recruitment season, many big factories have started to release recruitment information.

For ordinary people, entering a large factory is even half a foot on the boat of financial freedom

.Generally, large factories require at least 3 years of experience for a position to start, but there is still a phenomenon, that is, many highly educated candidates with 3 years of experience or more are passed in one shot.I believe that there must be a "hurdle" in this, so what is the "hurdle" of 3 years of Java experience?After reading this article, it will definitely help you.

First of all, this kind of technical post is definitely not defined by the number of years of work.3 years of work experience is just a pretense, the real thing has to be technical ability.If you look at the working years, there will not be so many highly educated talents hired by big factories with high salaries.I stayed up all night and sorted out a detailed list of Java job skills requirements in large factories. Most Java jobs above 20K basically require relevant experience in high concurrency and distribution.Seasoned interviewers should know that if the candidate has a comprehensive and in-depth understanding of concurrent programming, for a Java programmer, this can indicate that his technical skills are strong enough.

In the era of surge in Internet traffic, there are higher requirements for the concurrent performance, processing capability, and processing timeliness of applications. High concurrent programming has directly become a watershed between senior developers and novice developers.

Therefore, concurrent programming is definitely a must-test item for interviews in big factories.

.For example, what scenarios are pessimistic locking and optimistic locking suitable for?What is the essential difference between threads, processes and coroutines?What are the common high-concurrency distributed system architectures?Do you have any of these questions?

If you don't, don't worry. At the request of some fans, I will share with you the concurrency programming knowledge points recommended by Ali today, so that everyone can learn concurrency systematically and no longer get confused.

Okay, without further ado, let's get to the point.

This information is divided into three parts:

Java Concurrent Programming Basics, Java Concurrent Programming Advanced and Java Concurrent Programming Practice.

The following shows the directory

Part I Java Concurrent Programming Fundamentals

Part II Java Concurrent Programming Advanced

Java Concurrent Programming Practice
