Modern Java in Action
Modern Java in Action, released in November 2018, is the second edition of my best-selling book Java 8 in Action: Lambdas, streams and functional-style programming.
As of December 2018 it has sold 30,000+ copies world wide.
Modern Java in Action connects new features of the Java language with their practical applications. Using crystal-clear examples and careful attention to detail, this book respects your time. It will help you expand your existing knowledge of core Java as you master modern additions like the Streams API and the Java Module System, explore new approaches to concurrency, and learn how functional concepts can help you write code that’s easier to read and maintain.
You can order it on the publisher website.
Java 8 in Action
This is my first book, Java 8 in Action, published in 2014. It is a clearly written guide to the new features of Java 8. The book 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.
Real-world Software Development
I’m currently writing a new book with my friend Richard Warburton. The book is entitled Real-world Software Development: A Project-Driven Guide to Fundamentals in Java. It scheduled for release in summer 2019.
Explore the latest Java-based software development techniques and methodologies through the project-based approach in this practical guide. Unlike books that use abstract examples and lots of theory, Real-World Software Development shows you how to develop several relevant projects while learning best practices along the way.
Introducing Java 8
I wrote a free short book, Introducing Java 8, published by O’Reilly to get you started with Java 8. To learn about Java 8 in more details I recommend reading my reference book Java 8 in Action: Lambdas, streams and functional-style programming
Java SE 8 is perhaps the largest change to Java in its history, led by its flagship feature—lambda expressions. If you’re an experienced developer looking to adopt Java 8 at work, this short guide will walk you through all of the major changes before taking a deep dive into lambda expressions and Java 8’s other big feature: the Streams API.
