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.

Loom project

The Loom project ( may be the most significant of the projects listed in this chapter that can give Java a power boost. From the very early days almost 25 years ago, Java provided a relatively simple multi-threading model with a well-defined synchronization mechanism. We described it in Chapter 8, Multithreading and Concurrent Processing. This simplicity, as well as the overall simplicity and security of Java, was one of the main factors of Java's success. Java servlets allowed the processing of many concurrent requests and were at the foundation of Java-based HTTP servers.

The thread in Java is based on the OS kernel thread, though, which is a general-purpose thread. But the kernel OS thread was designed to perform many different system tasks too. It makes such a thread too heavy (requiring too many resources) for the business...
