Beta Books: What do I get?


Java is changing quickly—don’t be left behind. This book will keep you up to date on the amazing capabilities of the Java language introduced between versions 9 and 19. Whether you are using Java 8 or one of the newer versions of Java, this book will serve as your practical guide to explore and apply the features in these versions of Java.

Learn to properly use type inference and avoid its pitfalls. Use text blocks to write elegant multiline strings and embed XML and JSON documents in code. Design better OO code with records and sealed classes, and along the way, learn proper ways to apply these new ideas. Reduce verbosity and hidden errors in code using switch expressions and pattern matching syntax. Take your upgrade journey further by modularizing your Java code, to make it more secure and manage dependencies clearly. Leverage those capabilities to more easily and dynamically discover services. Learn to create highly performant and resilient asynchronous applications, using the brand new virtual threads (fibers) and structured concurrency.

Don’t tolerate clumsy old Java code; instead, benefit from the significant changes to the language in versions 9 through 19.

What You Need

To make use of all the features in this book, you’ll need at least Java 19.
