Java Closures and Lambda introduces you to significant new changes to the Java language coming out of what is termed Project Lambda. These new changes make their debut in Java 8, and their highlight is the long-awaited support for lambda expressions in the Java language. You’ll learn to write lambda expressions and use them to create functional interfaces and default methods for evolving APIs, among many other uses. The changes in Java 8 are significant. Syntax and usage of the language are changed considerably with the introduction of closures and lambda expressions. This book takes you through these important changes from introduction to mastery. Through a set of clear examples, you’ll learn to refactor existing code to take advantage of the new language features. You’ll learn what those features can do for you, and when they are best applied. You’ll learn to design and write new code having these important new features in mind from the very beginning. Clearly explains the fantastic benefits resulting from Project Lambda Explains the syntax and IDE support for the new features Shows how to streamline your code by bringing some of the benefits of functional programming to the Java language Illustrates parallelism in closures through Stream and Spliterator objects Explains API evolution by adding methods to existing interfaces without breaking existing interface implementations, a technique addressing potential multiple inheritance issues

相對於 JavaScript、Python、Scala 等本身支援一級函式（First class function）的語言，Java 開發者對於一級函式是比較陌生的，因而在 2010 年 JCD 中的議程 Lambda/Closure - 從 JavaScript、Python、Scala 到 Java SE 7，我簡單地從 JavaScript、Python、Scala 等語言的一級函式特性開始介紹，分享了 Java 要加入 Lambda/Closure 會有什麼樣的考量。 Java 的 Lambda 語法後來歷經了數次的討論與改變，後來確定在 Java SE 8 中引入 Lambda，也引進了因應新語法而帶來的 API 新功能，因而我在 2012 年 Java TWO 議程 Java SE 8 的 Lambda 連鎖反應中，從 Lambda 演算開始探討了 Lambda 的前世今生，以及會對 Java 帶來的新典範（Paradigm）與風格。 Java 引入的新典範其實有著函數式程式設計（Functional programming）的影子，想要善用 Java 引入的 Lambda 語法與新 API，先認識函數式程式設計會有非常大的幫助，因而在 2012 年 JCD 中，我於議程 Java 開發者的函數式程式設計中探討了函數式程式設計，以及在 Java 中如何適當地運用函數式風格。 Java SE 8 確定於 2014 年 3 月發表，而我發現過去的這幾個議程可以整理成為系列文章，讓大家可以認識 Java 中 Lambda 的前世今生。除此之外，最後並加上了 JDK8 Functional API 的介紹，讓本書對 JDK8 Lambda 的介紹更為完整。認識 Lambda/Closure 從 JavaScript 的函式物件談起什麼是 Closure？ Python 對 Lambda/Closure 的支援從 Scala 中借鏡 Java 的稻草人提案一級函式與 Lambda 演算 JDK8 Lambda 語法方法參考與建構式參考 Java 開發者的函數式程式設計初探函數式程式設計代數資料型態 List 處理模式不可變特性 JDK8 預設方法惰性 JDK8 Functional API 使用 Optional 取代 null Consumer、Function、Predicate 與 Supplier 使用 Stream 進行管線操作 Stream 的 reduce 與 collect Optional 與 Stream 的 flatMap Stream 與平行化

Intermediate level, for programmers fairly familiar with Java, but new to the functional style of programming and lambda expressions. Get ready to program in a whole new way. Functional Programming in Java will help you quickly get on top of the new, essential Java 8 language features and the functional style that will change and improve your code. This short, targeted book will help you make the paradigm shift from the old imperative way to a less error-prone, more elegant, and concise coding style that's also a breeze to parallelize. You'll explore the syntax and semantics of lambda expressions, method and constructor references, and functional interfaces. You'll design and write applications better using the new standards in Java 8 and the JDK. Lambda expressions are lightweight, highly concise anonymous methods backed by functional interfaces in Java 8. You can use them to leap forward into a whole new world of programming in Java. With functional programming capabilities, which have been around for decades in other languages, you can now write elegant, concise, less error-prone code using standard Java. This book will guide you though the paradigm change, offer the essential details about the new features, and show you how to transition from your old way of coding to an improved style. In this book you'll see popular design patterns, such as decorator, builder, and strategy, come to life to solve common design problems, but with little ceremony and effort. With these new capabilities in hand, Functional Programming in Java will help you pick up techniques to implement designs that were beyond easy reach in earlier versions of Java. You'll see how you can reap the benefits of tail call optimization, memoization, and effortless parallelization techniques. Java 8 will change the way you write applications. If you're eager to take advantage of the new features in the language, this is the book for you. What you need: Java 8 with support for lambda expressions and the JDK is required to make use of the concepts and the examples in this book.

Java 8 is a giant step forward for the Java language. In Project Lambda, Java gets a new closure syntax (lambda expressions), method-references, and default and static methods on interfaces. It manages to add many of the features of functional languages without losing the clarity and simplicity Java developers have come to expect. In addition, many of the existing Java core library classes have been enhanced with the new Streams API. This book will help you understand Java 8, including: Project Lambda, the new Date-Time API, Streams, default methods, the Nashorn Javascript engine, and more.
