What Java 9 Programming by Example Chapter Covers

  1. Chapter 1, Getting Started with Java 9, gives you a jump start in Java, helping you install it on your computer and run your first interactive programs using the new Jshell. This chapter covers a lot of detail about configuration with different IDEs and Java Power Shell (jps). You may skip this chapter if you already have been using an IDE tool for java development.
  2. Chapter 2, The First Real Java Program - Sorting Names. The key topic in this chapter is "Understanding the algorithm and language constructs" This chapter demonstrate different the power of Java 9 using different example and screen shots.
  3. Chapter 3, Optimising the Sort - Making Code Professional, develops the code further so that the code is reusable and not only a toy.
  4. Chapter 4, Mastermind - Creating a Game, is when some fun starts. We develop a game application that is interesting and not as trivial as it first seems, but we will do it.
  5. Chapter 5, Extending the Game - Run Parallel, Run Faster, shows you how to utilise the multi-processor capabilities of modern architecture. This is a very important chapter that details technologies, that only a few developers truly understand.
  6. Chapter 6, Making Our Game Professional - Do it as a Web-app, transforms the user interface from command-line to web browser-based, delivering better user experience.
  7. Chapter 7, Building a Commercial Web Application Using REST, takes you through the development of an application that has the characteristics of many commercial applications. We will use the standard REST protocol which has gained ground in enterprise computing.
  8. Chapter 8, Extending Our E-Commerce Application, helps you develop the application further utilising modern language features such as scripting and lambda expressions.
  9. Chapter 9, Building an Accounting Application Using Reactive Programming, teaches you how to approach some problems using reactive programming.
  10. Chapter 10, Finalizing Java Knowledge to a Professional Level, gives a bird's-eye view of developer topics that play an important role in the life of a Java developer, and which will guide you further in working as a professional developer.
