Java Structured Concurrency

Master Java's most significant concurrency upgrade with hands-on problems that build skill and confidence

Key Features

Solve 150+ problems that deepen your understanding of Project Loom
Explore structured concurrency, scoped values, and virtual threads in depth
Build modern, high-performance Java applications using practical design patterns

Book DescriptionTackling concurrency in Java has historically been complex, inefficient, and difficult to reason about-until now. This book guides you through Java's modern concurrency revolution introduced by Project Loom. Through over 150 real-world problems, you'll build deep expertise in virtual threads, structured concurrency, and scoped values, equipping you to write performant, maintainable, and scalable concurrent applications.
Using a problem-solution approach, this book encourages active learning as you develop, test, and refine your solutions while gaining insight into the trade-offs behind different concurrency decisions. You'll move from foundational concepts and API mechanics to internal workings, advanced design patterns, and complete case studies, making this the ideal reference to keep on your desk. Written by Anghel Leonard, a Java expert and prolific technical author, this book distills years of research and real-world experience into a comprehensive and approachable guide for modern Java concurrency.

By the end of this book, you'll master modern Java concurrency by solving real-world problems and applying proven multithreading design patterns effectively.What you will learn
