商品描述
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.
You Will
- 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
Who This Book is For
Java developers of any level. This knowledge is so fundamental to staying relevant in the Java job market that every developer needs to understand it for their career development.
商品描述(中文翻譯)
發現 Java 的 Project Loom 所引入的令人興奮的新 API。本快速指南涵蓋了 Java 開發人員理解虛擬執行緒、結構化併發和範圍值所需的所有基本概念。
作者 Ron Veen 和 David Vlijmincx 清楚地解釋了在 Java 21 中引入的虛擬執行緒相較於過去 25 年的傳統 Java 執行緒的優越性。接著，他們深入探討結構化併發如何通過將相關執行緒視為統一的工作單位來簡化互動，類似於結構化程式設計對常規程式設計的影響。之後，作者探討了第三個 Project Loom API 和範圍值，闡明了它們相較於常規的 ThreadLocals 的優勢，並提供了高效的使用見解。本書最後探討了常見的排程策略。
在本書結束時，您將對 Project Loom 背後的概念有堅實的理解，並能立即將這些知識應用到自己的程式碼中。
您將會：
- 發現虛擬執行緒是什麼、為什麼會創建它們，以及如何在您的程式碼中使用它們
- 獲得有關併發如何改善程式碼可觀察性的見解
- 編寫符合您需求的自定義 StructuredTaskScopes
- 理解為什麼應該用範圍值取代 ThreadLocals
- 知道多執行緒計算機程式的不同策略
本書適合對象：
任何級別的 Java 開發人員。這些知識對於在 Java 就業市場保持相關性至關重要，每位開發人員都需要理解它以促進其職業發展。
