Overview of this book

Java is one of the preferred languages among developers, used in everything right from smartphones, and game consoles to even supercomputers, and its new features simply add to the richness of the language. This book on Java programming begins by helping you learn how to install the Java Development Kit. You will then focus on understanding object-oriented programming (OOP), with exclusive insights into concepts like abstraction, encapsulation, inheritance, and polymorphism, which will help you when programming for real-world apps. Next, you’ll cover fundamental programming structures of Java such as data structures and algorithms that will serve as the building blocks for your apps. You will also delve into core programming topics that will assist you with error handling, debugging, and testing your apps. As you progress, you’ll move on to advanced topics such as Java libraries, database management, and network programming, which will hone your skills in building professional-grade apps. Further on, you’ll understand how to create a graphic user interface using JavaFX and learn to build scalable apps by taking advantage of reactive and functional programming. By the end of this book, you’ll not only be well versed with Java 10, 11, and 12, but also gain a perspective into the future of this language and software development in general.

Amber project

The Amber project (https://openjdk.java.net/projects/amber) is focused on small Java syntax enhancements that would make it more expressive, concise, and simpler. These improvements are going to increase the Java programmers' productivity and make their code-writing more enjoyable.

Two Java features created by the Amber project have been delivered already and we talked about them:

  • The type holder var (see Chapter 1, Getting Started with Java 12) has been available to use since Java 10.
  • The local-variable syntax for lambda parameters (see Chapter 13, Functional Programming) was added to Java 11.
  • The less-verbose switch statement (see Chapter 1, Getting Started with Java 12) was introduced as a preview feature with Java 12.

Other new features are going to be released with the future Java version. We will look closer only at five of them in the following subsections...
