Java 9 with JShell

The release of Java 9 has brought the REPL, known as JShell, which will make experiments and prototyping much more straightforward than the old IDE-based project-led approach. Java has also acquired a module system which makes discovery, loading and integrity checking much easier than the old JAR format. Together with the emphasis on functional programming since Java 8, this book shares a new Java landscape, enhancing programmer productivity and a new approach to Java object orientation.
