Learn Java 12 Programming

By: Nick Samoylov

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.

This chapter introduced readers to the concepts of OOP and how they are implemented in Java. It provided an explanation of each concept and demonstrated how to use it in specific code examples. The Java language constructs of class and interface were discussed in detail. The reader also has learned what overloading, overriding, and hiding are and how to use the final keyword to protect methods from being overridden.

From the Polymorphism in action section, the reader learned about the powerful Java feature of polymorphism. This section brought all the presented material together and showed how polymorphism stays in the center of OOP.

In the next chapter, the reader will become familiar with Java language syntax, including packages, importing, access modifiers, reserved and restricted keywords, and some aspects of Java reference types. The reader will also learn how to...
