Preface

The world has been waiting for Java 9 for a long time. More specifically, we've been waiting for the Java Platform Module System, and Java 9 is finally going to deliver it. If all goes as planned, we'll finally have true isolation, giving us, potentially, smaller JDKs and more stable applications. That's not all that Java 9 is offering of course; there is a plethora of great changes in the release, but that's certainly the most exciting. That said, this book is not a book about the module system. There are plenty of excellent resources that can give you a deep dive into the Java Platform Module System and its many implications. This book, though, is a much more practical look at Java 9. Rather than discussing the minutiae of the release, as satisfying as that can be, what we'll do over the next few hundred pages is look at different ways all of the great changes in recent JDK releases--especially Java 9--can be applied in practical ways.

When we're done, you'll have ten different projects that cover a myriad of problem areas, from which you can draw usable examples as you work to solve your own unique challenges.
