Content Introduction

This book introduces Java threading and concurrency in a more comprehensible way, and is a perfect Java concurrency reference manual. From the basic concepts of concurrency and thread safety, the book describes how to use the basic concurrency building blocks provided by class libraries to avoid concurrency hazards, construct thread-safe classes and validate thread-safe rules, how to combine small thread-safe classes into larger thread-safe classes, and how to leverage threads to increase throughput for concurrent applications. How to identify tasks that can be executed in parallel, how to improve the responsiveness of single-threaded subsystems, how to ensure that concurrent programs perform the expected tasks, how to improve the performance and scalability of concurrent code, and so on, and finally introduce some advanced topics such as explicit locks, atomic variables, nonblocking algorithms, and how to develop custom synchronization tool classes.

This book is intended for developers of Java programs to read.
