Drunk Ali P7 shares concurrent programming suits, and it’s not my problem if you can’t learn

[Concurrent programming] is a necessary skill for every architect to build a foundation. There is no room for it, and it is just one word: do it!

A few months ago, relying on super invincible luck, I got the most complete [high concurrency package] from Ali Daniel, and went back and died for 100 days (forgive me for this scum, it took a long time, I only went out and upgraded a few days ago) . It just so happens that I haven't talked about high concurrency for a long time. Today, I have to come to the most complete [High Concurrency Package]

 

Don’t worry, let’s test our own depth of knowledge first

Let me first ask you 20 essential knowledge points for high concurrent programming, how about trying it?

Question 1: What is thread safety?

Question 2: What is the visibility issue of shared variables?

Question 3: What about atomicity?

Question 4: Introduction to CAS?

Question 5: What is a reentrant lock?

Question six: Synchronized keywords?

Question 7: ReentrantReadWriteLock, introduce?

Question eight: Volatile variable?

Question 9: Optimistic lock and pessimistic lock?

Question ten: Exclusive lock and shared lock?

Question 11: Fair lock and unfair lock?

Question 12: Introduction to AbstractQueuedSynchronizer?

Question 13: The principle of CountDownLatch?

Question 14: ReentrantLock exclusive lock principle?

Question 15: The principle of ReentrantReadWriteLock?

Question 16: What is the reordering problem?

Question 17: What is an interrupt?

Question 18: How does FutureTask work?

Question 19: Briefly describe the principle of ConcurrentHashMap?

Dumbfounded? Don't panic, show you the answer... 33 pages of super long analysis (this will not be parsed one by one, too much, space is limited, in one sentence, directly message me [Concurrent Programming] and share the original file with you for free Yes)

Now you know your flaws, right? Let’s take a look at a brain map of knowledge and rationalize it

Concurrent programming knowledge brain map (total)

The above one is a complete outline of the brain map of concurrent programming knowledge. The denseness is not particularly clear. You can see the detailed diagram below: Java Memory Model (JMM), Concurrency Foundation, ThreadLocal+ForkJoin, Concurrency Tool Class, Java Concurrency Collection, Thread Pool, Blocking queue

Details of the Java Memory Model (JMM)

All the brain maps here are drawn with the xmind software. The original images cannot be uploaded, so each one is shown in the form of screenshots, but all the originals are below, free to share, forwarding + private message to my keywords [Concurrent programming] Just fine.

Okay, that's all for concurrent programming. If you can finish this [High Concurrency Package], are you afraid to get it done? Can't do an interviewer? Can't enter the big factory?

Don’t panic, don’t panic, friends who want to study hard can forward + private message keywords [concurrent programming], find the editor to share this [high concurrency package ]: interview knowledge points + knowledge mind map (total + details) ) + Trapping notes ("JAVA Concurrent Programming Practice. PDF" "Java Multithreaded Programming Core Technology_Complete Edition" "Handwritten Four Concurrent Notes: Concurrent Programming + Principle + Mode + Application") etc.
