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 this chapter, we built a different kind of project. We've had applications that run on Android, and some that run on the desktop. This one, though, runs on both platforms simultaneously. One is no good without the other. That requires that we build things a bit differently to make sure the two are synchronized. While there are a variety of ways to go about this, we chose to use a REST server on the phone, with the desktop acting as a REST client.

By the end of the chapter, we built an Android application that provides not only a user interface, but a background process (called Service), and embedded our REST server in the Android application using Jersey and its Java SE deployment option. You also learned how to interact with text (SMS) messages on Android using the system-provided Content Providers and platform APIs, and streaming those messages to the client using Server-Sent Events. We demonstrated how to send messages between processes/threads in Android using Intents, broadcasts...
