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.

Defining the user interface

When building the user interface for a JavaFX application, you can do it in one of two ways: code or markup. To keep our code smaller and more readable, we'll build the user interface using FXML--the XML-based language created specifically for JavaFX to express user interfaces. This presents us with another binary choice--do we write the XML by hand, or do we use a graphical tool? Again, the choice is a simple one--we'll use a tool, Scene Builder, which is a WYSIWYG tool originally developed by Oracle and now maintained and supported by Gluon. We will, however, also be looking at the XML source so that we can understand what's being done, so if you don't like using a GUI tool, you won't be left out.

Installing and using Scene Builder is, as you would expect, pretty straightforward. It can be downloaded from Once installed, you need to tell NetBeans where to find it, which can be done in the Settings window, under Java | JavaFX...
