Java 8 in Action: Lambdas, Streams, and Functional-Style Programming (Unabridged‪)‬

Every new version of Java is important, but Java 8 was a game changer. Java 8 in Action is a clearly written guide to the new features of Java 8. It begins with a practical introduction to lambdas, using real-world Java code. Next, it covers the new Streams API and shows how you can use it to make collection-based code radically easier to understand and maintain. It also explains other major Java 8 features including default methods, Optional, CompletableFuture, and the new Date and Time API. With Java 8's functional features you can write more concise code in less time and also automatically benefit from multicore architectures. It's time to dig in!

This book is written for programmers familiar with Java and basic OO programming.

What's inside:


How to use Java 8's powerful new features
Writing effective multicore-ready applications
Refactoring, testing, and debugging
Adopting functional-style programming
