商品描述
Discover all the new features and changes in Java 9, including module systems―JPMS or Project Jigsaw. This book covers the whole Java application development life cycle. You'll review all the important concepts, including module descriptor, unnamed module, automatic module, and command line tools.
Exploring Java 9 also serves as a practical guide for migration to module systems. Code samples from real-world scenarios solidify a foundation for learning and development and allow you to apply best practices in actual development.
Additionally, you'll learn about concurrency, ECMAScript 6 features in Nashorn and Parser API, stack-walking API, Stream and Optional, utilities classes, and I/O. And it’s now possible to build modularized applications in Java. You'll see how JPMS affects not only the JDK itself, but also applications that are developed upon it.
What You'll Learn
• Build modularized applications in Java
• Migrate to module systems
• Master enhanced method handles
Who This Book Is For
Java developers with basic development skills
商品描述(中文翻譯)
發現 Java 9 中所有的新功能和變更，包括模組系統―JPMS 或 Project Jigsaw。本書涵蓋整個 Java 應用程式開發生命週期。您將回顧所有重要概念，包括模組描述符、未命名模組、自動模組和命令列工具。
《探索 Java 9》同時也是遷移到模組系統的實用指南。來自真實場景的程式碼範例鞏固了學習和開發的基礎，並使您能夠在實際開發中應用最佳實踐。
此外，您將學習到併發、Nashorn 中的 ECMAScript 6 特性和 Parser API、堆疊遍歷 API、Stream 和 Optional、工具類別以及 I/O。現在可以在 Java 中構建模組化應用程式。您將看到 JPMS 不僅影響 JDK 本身，還影響基於它開發的應用程式。
您將學到的內容：
• 在 Java 中構建模組化應用程式
• 遷移到模組系統
• 精通增強的方法句柄
本書適合對象：
具備基本開發技能的 Java 開發人員
