What this book covers

Chapter 1, Introduction, gives a quick overview of the new features in Java 9, and also covers some of the major features of Java 7 and 8 as well, setting the stage for what we'll be using in later chapters.

Chapter 2, Managing Process in Java, builds a simple process management application (akin to Unix's top command), as we explore the new OS process management API changes in Java 9.

Chapter 3, Duplicate File Finder, demonstrates the use of the New File I/O APIs in an application, both command line and GUI, that will search for and identify duplicate files. Technologies such as file hashing, streams, and JavaFX are heavily used.

Chapter 4, Date Calculator, shows a library and command-line tool to perform date calculations. We will see Java 8's Date/Time API exercised heavily.

Chapter 5, Sunago - A Social Media Aggregator, shows how one can integrate with third-party systems to build an aggregator. We'll work with REST APIs, JavaFX, and pluggable application architectures.

Chapter 6, Sunago - An Android Port, sees us return to our application from Chapter 5, Sunago - A Social Media Aggregator.

Chapter 7, Email and Spam Management with MailFilter, builds a mail filtering application, explaining how the various email protocols work, then demonstrates how to interact with emails using the standard Java email API--JavaMail.

Chapter 8, Photo Management with PhotoBeans, takes us in a completely different direction when we build a photo management application using the NetBeans Rich Client Platform.

Chapter 9, Taking Notes with Monumentum, holds yet another new direction. In this chapter, we build an application--and microservice--that offers web-based note-taking similar to several popular commercial offerings.

Chapter 10, Serverless Java, moves us into the cloud as we build a Function as a Service system in Java to send email and SMS-based notifications.

Chapter 11, DeskDroid - A Desktop Client for Your Android Phone, demonstrates a simple approach for a desktop client to interact with an Android device as we build an application to view and send text messages from our desktop.

Chapter 12, What's Next?, discusses what the future might hold for Java, and also touches upon two recent challengers to Java's preeminence on the JVM--Ceylon and Kotlin.
