The Well-Grounded Java Developer, Second Edition

Understanding Java from the JVM up gives you a solid foundation to grow your expertise and take on advanced techniques for performance, concurrency, containerization, and more.

In The Well-Grounded Java Developer, Second Edition you will learn:

    The new Java module system and why you should use it
    Bytecode for the JVM, including operations and classloading
    Performance tuning the JVM
    Working with Java’s built-in concurrency and expanded options
    Programming in Kotlin and Clojure on the JVM
    Maximizing the benefits from your build/CI tooling with Maven and Gradle
    Running the JVM in containers
    Planning for future JVM releases

The Well-Grounded Java Developer, Second Edition introduces both the modern innovations and timeless fundamentals you need to know to become a Java master. Authors Ben Evans, Martijn Verburg, and Jason Clark distill their decades of experience as Java Champions, veteran developers, and key contributors to the Java ecosystem into this clear and practical guide. You’ll discover how Java works under the hood and learn design secrets from Java’s long history. Each concept is illustrated with hands-on examples, including a fully modularized application/library and creating your own multithreaded application.

Foreword by Heinz Kabutz.
