Java 9 for Programmers

“Content is expertly covered. Java 9 introduces modules—a major shake-up to the Java ecosystem that brings numerous benefits, but also new challenges, terminology and patterns. Developers moving to Java 9 must know how to interact with modules, and this book does an expert job at clearly introducing these concepts. The book also covers numerous other Java 8 and Java 9 features, such as JShell, lambda expressions and JavaFX improvements. With this knowledge, developers can realize massive productivity gains by benefiting from the state of the art in Java. I highly recommend this book to all professionals aiming to keep current with the very latest Java developments.”
—Jonathan Giles, Consulting Member of Technical Staff, Oracle

“Provides a thorough introduction to the JShell tool for discovery. Java 9 for Programmers takes full advantage of that with interesting exercises.”
—Robert Field, JShell Architect, Oracle

“Covers JavaFX functionality that makes it easy to create nice, active user interfaces. A great overview on how concurrency can help developers leverage multi-core processors.”
—Johan Vos, CTO, Cloud Products at Gluon, Java Champion

“The combination of theory, clear explanation and example code makes this both a great learning experience and an excellent reference that is useful for any developer to have close at hand. Provides a great overview of the Java Platform Module System! I particularly like the way you explained the importance of modularity. Code examples are sufficiently complex to be realistic, but simple enough to understand. Covers all the topics I expected to see on modularity (more actually, especially around visualizing dependencies).”
—Trisha Gee, JetBrains, Java Champion

“Nice job on JShell. The most recent changes to Java are by far the biggest evolutions to the language and the platform in over 20 years. The changes are complex and intriguing, but Paul and Harvey have distilled the concepts to an easily digestible form, with plenty of examples. This book is an incredible, comprehensive source for deeper learning of Java and its ecosystem.”
—Dr. Venkat Subramaniam, President, Agile Developer, Inc. and Instructional Professor, University of Houston

“Gives the benefit of the wisdom derived from many years of software development experience!”
—Edward F. Gehringer, North Carolina State University

“Great book for studying the world’s most popular programming language. Introduces good design practices and methodologies from the beginning. Excellent starting point for developing high-quality, robust Java applications. Really good, clear explanation of object-oriented programming fundamentals. Excellent polymorphism chapter. Introduces JavaFX, the great new way to develop client applications in Java—I like the use of Scene Builder to create GUIs with drag-and-drop design rather than by hand, which shows the way it should be done. Excellent generic collections chapter. Covers lambdas and streams well.”
—Simon Ritter, Oracle (now Deputy CTO at Azul Systems)

“Want to take your Java skills to the next level? This book is the ultimate guide. I’ve enjoyed and learned much from it. Every major Java feature is masterfully covered. This is more than a book—it’s a career-building program. I really enjoyed t
