See all formats and editions

Imagine writing Java code that reads like the problem statement, code that's highly expressive, concise, easy to read and modify, and has reduced complexity. With the functional programming capabilities in Java, that's not a fantasy. This book will guide you from the familiar imperative style through the practical aspects of functional programming, using plenty of examples. Apply the techniques you learn to turn highly complex imperative code into elegant and easy-to-understand functional-style code. Updated to the latest version of Java, this edition has four new chapters on error handling, refactoring to functional style, transforming data, and idioms of functional programming.

Don't struggle with the limitations of the imperative style; instead learn to combine object-oriented programming with the functional style to reduce the accidental complexity. Harness the functional programming capabilities of Java to create applications where the program reveals its intentions and your team can quickly understand and modify code to align with changing business requirements. Unlock the power of lambda expressions and the Streams API to turn the oft-written spaghetti code into highly concise, expressive, elegant, and maintainable code. See how Streams make the arduous task of parallelizing code as easy as flipping a switch when superior speed is necessary.

Apply design patterns built around lambda expressions, safely manage resource allocations, use memoization, and learn to transform data into different forms, all while honoring immutability, and providing thread safety to leverage lazy evaluation for efficiency and parallel execution for performance. Move beyond the basics, explore the idioms for writing functional programs. Learn to think functionally by refactoring legacy code into the functional style. And, if your code runs aground due to failures, learn to properly handle errors the functional way.

Don't drown in theory; instead learn the practical functional programming techniques to create superior Java code.

Functional Programming in Java: Harness the Power of Streams and Lambda Expressions

From the Preface

Who’s This Book For

This book is for programmers well versed in object-oriented programming in Java and keen to learn and apply the functional programming facilities. You’ll need good experience programming in previous versions of Java, at least Java 5, to make the best use of this book.

Programmers mostly interested in JVM languages like Scala, Groovy, JRuby, Kotlin, and Clojure can benefit from the examples in this book and can relate back to the facilities offered in those languages. They can also use the examples to help fellow Java programmers on their teams.

Programmers experienced with the functional style of programming in other languages and who are now involved in Java projects can use this book, as well. They can learn how what they know translates to the specifics of the lambda expressions’ usage in Java.

Programmers who are familiar with lambda expressions in Java can use this book to help coach and train their team members who are getting up to speed in this area.

What’s in This Book

This book will help you get up to speed with the functional programming capabilities in Java, to think in the elegant style, and to benefit from the additions to the Java Development Kit (JDK) library. We’ll take an example-driven approach to exploring the concepts. Rather than discuss the theory of functional programming, we’ll dive into specific day-to-day tasks to apply the elegant style. This approach will quickly get these concepts under our belts so we can put them to real use on projects right away.

On the first read, take the time to go over the chapters sequentially as we build upon previously discussed concepts and examples. Each chapter closes with a quick summary to recap what was covered. Later, when working on applications, take a quick glance at any relevant example or section in the book. There’s also a syntax appendix for quick reference.
