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.

If Venkat wrote it, buy it - you will not be disappointed!

An amazing and engaging author. This book does an excellent job explaining how to take advantage of Functional Programming now that it's here in Java 8. Venkat is a rare creature, who has not only a deep understanding of the inner working of Java and program languages in general, but also ENTERTAINS as he explains. If you've been lucky enough to see Venkat present on this subject, you'll find the same humorous, self-effacing approach in his writing. If you haven't seen him, Google! You won't be disappointed.

Functional Programming in Java 8 is a paradigm shift - this book helps the java programmer understand this new way of thinking about how we compose our objects to benefit from FP. As a Java Professional of many years, this book really helped me understand this new way (in Java) to write robust, reusable, and efficient code.

Finally, an excellent side by side demonstration of the old procedural style with the new functional style. This book explains what functional programming means, and why it's important, while introducing the new Java 8 features. You can't go wrong with this book.

This book is well written, detailed examples and user friendly explanation. But it lacks more detailed explanations for lambda.
This book is not for novice but intermediate or higher.

Shallow and Annoying

Reviewed in the United States on June 28, 2014

Verified Purchase

I like Java 8's new functional programming (FP) features, but I don't like this book. The book is shallow. Mainly he just writes simple examples and then repeats in prose what the code does.

The author's constant hyping and cheering for the new FP features becomes annoying fast. He over uses adjectives like, "powerful", "easy", and "effortless". The new features are nice, but they're not that much more powerful than Java already was. Any program you can write in Java 8, you can also write in Java 7 or 6 or 5 ...

Java's new FP features can make code simpler in some cases, which is good. But these new features can also make the code harder to understand. It's possible to make code too concise - fit too much on a single line (as some programmers can't help themselves from doing). Unfortunately, this can makes code harder to understand by someone who must maintain it later. The FP features should be used with care.

I didn't realize that Amazon has a seven day return policy on Kindle books. Had I known this, I would've returned it.

I don't recommend this book or author.

I really like this book. I have watched some talks on youtube by the author which I really enjoyed. The concepts and ideas are explained really well.

Great book

This book is still relevant in 2022. I’ve been using Java 11 in work and a lot of what is covered here in Java 8 is still useful.

I find reading for the first few chapters is fine but in later chapters I needed to program along to make it stick.

I’d recommend checking out the authors talks on YouTube too.

A great and concise read on Java 8 changes

I got this book the other day and so far it appears to be a great read if you want to get up to date with the changes in Java 8. It is only about 150 pages, sticks to the point and yet goes into enough depth to be really useful. So far very much recommended.

Great book, with really useful examples. Its written for people with good knowledge of coding/java, and provides lots of examples of now to solve common problems using older versions of java, and then compares this with how those problems can be solved using the functional programming features of Java8
