Overview of this book

Java is one of the most commonly used software languages by programmers and developers. In this book, you’ll learn the new features of Java 11 quickly and experience a simple and powerful approach to software development. You’ll see how to use the Java runtime tools, understand the Java environment, and create a simple namesorting Java application. Further on, you'll learn about advanced technologies that Java delivers, such as web programming and parallel computing, and will develop a mastermind game. Moving on, we provide more simple examples, to build a foundation before diving into some complex data structure problems that will solidify your Java 11 skills. With a special focus on the features of new projects: Project Valhalla, Project Panama, Project Amber, and Project Loom, this book will help you get employed as a top-notch Java developer. By the end of the book, you’ll have a firm foundation to continue your journey toward becoming a professional Java developer.

Coding the sort

Maven and the IDE created the files for the sort program. They form the skeleton for our code, and now it is time to grow some muscles on them to let it move. We spent quite some time setting up the project by visiting the different build tools, only to learn how to compile the code.

I hope that this did not distract you much, but anyhow, we deserve to see some real code.

First, we will create the code for the sorting code, and after that, the code that invokes the sorting. The code that invokes the sorting is a kind of testing code. For simplicity, we will now simply use a public static void main() method to start the code. We will use the test framework in later chapters.

As for now, the code for the sorting will look like this:

var n = names.length;
while (n > 1) {
    for (var j = 0; j < n - 1; j++) {
        if (names[j].compareTo(names[j + 1]) &gt...
