About the Book
Who is this for?
This book is for anyone who wants to learn more about Java programming up to and including Java 8 and 9.
Praise for "What's New in Java 8"
If you're just getting to Java 8, I definitely recommend @adamldavis' book -- very concise and helpful. -Fred Jonsson
What is covered?
Java and the JVM platform have made huge strides in the past several years. In Project Lambda, Java got lambda expressions, method-references, and default and static methods on interfaces. Java 9 adds modularity, jshell, and Reactive support. At the same time, many new frameworks have reached full maturity and vastly improved over the previous models for building, testing, and developing web applications.
This book will help you understand:
- Java 9, including: Project Jigsaw, JShell, language updates, and Reactive support.
- Java 8, including: Project Lambda, the new Date-Time API, Streams, default methods, Nashorn, and more.
- Concurrent programming such as Akka, Fork/Join, Futures, Promises, Parallel Streams, and RxJava.
- Great web frameworks in Java, such as SpringBoot, Spark, Play, and Ratpack.
- The fundamentals of Groovy and how it can improve your Java projects.
- Testing with JUnit and Spock.
- Building with Gradle.
- Much more...

Electronic Frontier Foundation
Defending your civil liberties in a digital world.
https://www.eff.org/Based in San Francisco, EFF is a donor-supported membership organization working to protect fundamental rights regardless of technology.
From the Internet to the iPod, technologies are transforming our society and empowering us as speakers, citizens, creators, and consumers. When our freedoms in the networked world come under attack, the Electronic Frontier Foundation (EFF) is the first line of defense. EFF broke new ground when it was founded in 1990—well before the Internet was on most people's radar—and continues to confront cutting-edge issues defending free speech, privacy, innovation, and consumer rights today. From the beginning, EFF has championed the public interest in every critical battle affecting digital rights.
