“Functional Programming in Java” is a new book written to help readers get on top of the new, essential Java 8 language features and the functional style that will change and improve your code. It’s a short, targeted book.

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. “Functional Programming in Java” 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, memorization, and effortless parallelization techniques.

Java 8 with support for lambda expressions and the JDK is required to make use of the concepts and the examples in this book. “Functional Programming in Java” is available for e-readers in epub, mobi, and PDF formats direct from the publisher and in paperback from fine bookstores worldwide.
