Overview of this book

Java is a powerful language that has applications in a wide variety of fields. From playing games on your computer to performing banking transactions, Java is at the heart of everything. The book starts by unveiling the new features of Java 9 and quickly walks you through the building blocks that form the basis of writing applications. There are 10 comprehensive projects in the book that will showcase the various features of Java 9. You will learn to build an email filter that separates spam messages from all your inboxes, a social media aggregator app that will help you efficiently track various feeds, and a microservice for a client/server note application, to name a few. The book covers various libraries and frameworks in these projects, and also introduces a few more frameworks that complement and extend the Java SDK. Through the course of building applications, this book will not only help you get to grips with the various features of Java 9, but will also teach you how to design and prototype professional-grade applications with performance and security considerations.

Summary


With that, our application is done. So, what have we covered? From the project description, this seemed like a pretty simple application, but as we started breaking down the requirements and delving into the implementation, we ended up covering a lot of territory--a scenario that is not at all uncommon. We built another multi-module Maven project. We introduced Java concurrency, including basic Thread management and ExecutorService usage, as well as the Java Persistence API, showing basic @Entity definition, EntityManagerFactory/EntityManager usage, and JPAQL query authoring. We discussed creating file hashes using the MessageDigest classes, and demonstrated the new file I/O APIs, including the directory tree walking APIs. We also built a more complex user interface in JavaFX using nested containers, "linked" ListView instances, and bound properties.

That's quite a bit for such a "simple" project. Our next project will also be relatively simple, as we build a command-line date calculator...
