Big data shared source code
In the career of back-end programmers, if you have high concurrent experience, you can often get more opportunities than others. There is a simple reason. High concurrency will involve various technical problems, such as interface response timeout, frequent GC, large data storage, deadlock and so on. If you can handle a high concurrency programmer, the technical depth will not be bad.

In order to better understand Java concurrency, I specially got a handwritten JDK source code analysis manual and concurrent programming atlas from a friend of Ali some time ago. Let's see:

JDK source code analysis manual

Based on JDK7 and JDK 8, the source code of the whole contract is analyzed comprehensively. The implementation of most concurrent functions in JDK8 is the same as that in JDK 7, but some additional features are added. For example, CompletableFuture, the new implementation of ConcurrentHashMap, StampedLock, LongAdder, etc.

Concurrent programming atlas

Contains a lot of graphic and source code analysis to help you understand relevant knowledge. With the help of these pictures and texts, learning in this order can at least give you a simple introduction.

Because there are too many details in these materials, I can only take screenshots of some knowledge points and give a rough introduction. Each node has more detailed content!

I hope you can gain something after reading it ~
