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.

Java Standard and External Libraries

It is not possible to write a Java program without using the standard libraries, also called Java Class Library (JCL). That is why a solid familiarity with such libraries is as vital for successful programming as the knowledge of the language itself.

There are also non-standard libraries, called external libraries or third-party libraries because they are not included in Java Development Kit (JDK) distribution. Some of them have long become a permanent fixture of any programmer toolkit.

To keep track of all the functionality available in these libraries is not easy. That is because an Integrated Development Environment (IDE) gives you a hint about the language possibilities, but it cannot advise about the functionality of a package not imported yet. The only package that is imported automatically is java.lang.
