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.

Implementing QuickSort

Quicksort, as we have already discussed, is made of two major parts. One is partitioning and the other one is doing the partitioning recursively until the whole array is sorted. To make our code modular and ready to demonstrate the JPMS module-handling feature, we will develop the partitioning and the recursive sorting into separate classes and in a separate package. The complexity of the code will not justify this separation.

The partitioning class

The partitioning class should provide a method that moves the elements of the collection based on a pivot element, and we will need to know the position of the pivot element after the method finishes. The signature of the method should look something like...
