Java parallel atomic operation class parsingprefaceThe JUC package provides a number of atomic operation classes, which are implemented using the non blocking algorithm CAS. Compared with the atomic operation using locks, the performance is greatly improved.Since the principles of atomic operations are roughly the same, this article only explai ...

Explain the AQS source code hand in hand 1, Overview This article will take ReentrantLock as an example to show you the source code of AQS. In fact, it is not difficult. The following is a small case of fair lock. You can run and feel it yourself. The following will take you to read the source code bit by bit. If you look at it carefully, you ...

1, Principle of Atomic atomic class:          Atomic atomic operation class is implemented based on lockless CAS + volatile, and all methods in the class are decorated with final to further ensure thread safety. The specific implementation of CAS algorithm lies in the Unsafe class. All methods of Unsafe ...
