Java 9 Programming By Example

This is the code repository for Java 9 Programming By Example, published by Packt. It contains all the supporting project files necessary to work through the book from start to finish.

About the Book

This book gets you started with essential software development easily and quickly, guiding you through Java’s different facets. By adopting this approach, you can bridge the gap between learning and doing immediately. You will learn the new features of Java 9 quickly and experience a simple and powerful approach to software development. You will be able to use the Java runtime tools, understand the Java environment, and create Java programs.

We then cover more simple examples to build your foundation before diving to some complex data structure problems that will solidify your Java 9 skills. With a special focus on modularity and HTTP 2.0, this book will guide you to get employed as a top notch Java developer.

By the end of the book, you will have a firm foundation to continue your journey towards becoming a professional Java developer.

Instructions and Navigation

All of the code is organized into folders. Each folder starts with a number followed by the application name. For example, Chapter02.

The code will look like the following:


public interface Sort { 
 void sort(SortableCollection collection); 

To immerse into the content of this book and to soak up most of the skills and knowledge, we assume that you already have some experience with programming. We do not assume too much but hope that you already know what a variable is, that computers have memory, disk, network interfaces, and what they generally are. In addition to these basic skills, there are some technical requirements to try out the code and the examples of the book. You need a computer—something that is available today and can run Windows, Linux, or OSX. You need an operating system and, probably, that is all you need to pay for. All other tools and services that you will need are available as open source and free of charge. Some of them are also available as commercial products with an extended feature set, but for the scope of this book, starting to learn Java 9 programming, those features are not needed. Java, a development environment, build tools, and all other software components we use are open source.
