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.

In the process of doing so, we discovered the Jackson JSON Parser and used it to marshal and unmarshal POJOs to and from the disk. We used the ControlsFX class, BeanPathAdapter, to bind non-JavaFX-aware POJOs to JavaFX controls, and the Quartz Job Scheduling Library to execute code on a schedule. Finally, we wrapped up our application using the Java Service Wrapper to create installation artifacts.

We're left with what I hope is an application that is both interesting and helpful. There are several ways to improve on it, of course, if you feel so motivated. The account/rule data structure could be extended to allow defining global rules that are shared across accounts. The GUI...
