Discover the exciting new APIs introduced by Java's Project Loom. This quick guide covers all the essential concepts the Java developer needs in order to understand virtual threads, structured concurrency, and scoped values.Authors Ron Veen and David Vlijmincx clearly explain the superiority of virtual threads, introduced in Java 21, over the traditional Java threads of the past 25 years. Then they dive into how structured concurrency streamlines interactions by treating related threads as a unified unit of work, akin to the impact of structured programming on regular programming. From there, the authors explore the third Project Loom API and scoped values, clarifying their advantages over regular ThreadLocals and providing efficient usage insights. The book concludes with an exploration of common scheduling strategies.By the end of this book, you will have a solid understanding of the concepts behind Project Loom and will be able to immediately apply this knowledge to your own code .What You Will Learn Discover what virtual threads are, why they were created, and how to use them in your code Gain insight into how concurrency improves the observability of code Write your own StructuredTaskScopes tailored to your needs Understand why you should replace ThreadLocals with Scoped Values Know the different strategies for multithreaded computer programs
