This chapter, and subsequent chapters, features Java 11. The Standard Edition (SE) of the Java platform can be downloaded from Oracle's official download site (http://www.oracle.com/technetwork/java/javase/downloads/index.html).

An Integrated Development Environment (IDE) software package is sufficient. IntelliJ IDEA, from JetBrains, was used for all coding associated with this chapter and subsequent chapters. The Community version of IntelliJ IDEA can be downloaded from the website (https://www.jetbrains.com/idea/features/).

This chapter's source code is available at GitHub at the URL (https://github.com/PacktPublishing/Mastering-Java-11-Second-Edition).
