There is much more that can be discussed of course, about Java 10 and these two languages, and the myriad of other projects happening in and around the Java Virtual Machine. After over 20 years of development, Java--the language and the environment--is still going strong. In the pages of this book, I've tried to demonstrate some of these great advancements in the language, giving you a variety of starting points for your own projects, sample code to study and reuse, and explanations of various libraries, APIs, and technologies that may be helpful in your day-to-day work. I hope you've enjoyed the examples and explanations as much as I've enjoyed preparing them, and, more importantly, I hope they help you build the Next Big Thing.
Good luck!
