(Java concurrent programming practice introduces Java threads and concurrency easily, which is a perfect Java concurrency reference manual. Starting from the basic concepts of concurrency and thread safety, the book introduces how to use the basic concurrency building blocks provided by the class library, the rules for preventing concurrency risks, structuring thread safety classes, and verifying thread safety, how to combine small thread safety classes into larger thread safety classes, how to use threads to improve the throughput of concurrent programs, and how to identify commands that can be performed in parallel, How to improve the responsiveness of the single line program subsystem, how to ensure that the concurrent programs perform the expected commands, how to improve the function and scalability of the concurrent code, and finally introduced some advanced topics, such as explicit locking, atomic variables, non blocking algorithms, and how to develop customized synchronization tool classes. The friends who need can download and try it! Java concurrent programming practice is suitable for Java program developers to read. This book provides Java developers with rare knowledge in the field of thread programming. When I read this book, I will be greatly inspired. Part of the reason is that it introduces the API in the concurrency field of Java in detail, but more importantly, it introduces the messy concurrency knowledge in a thorough and understandable way, which is difficult to compare with other books.)
