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.

Reserved and restricted keywords

The keywords are the words that have particular meaning for a compiler and cannot be used as identificators. There are 51 reserved keywords and 10 restricted keywords. The reserved keywords cannot be used as identificators anywhere in the Java code, while the restricted keywords cannot be used as identificators only in the context of a module declaration.

Reserved keywords

The following is the list of all Java-reserved keywords:

abstract assert boolean break byte
case catch char class const
continue default do double else
enum extends final finally float
for if goto implements import
instanceof int interface long native
new package private protected public
return short static...
