The first part of the book brings the reader into the world of Java programming. It starts with basic Java-related definitions and the main terms, walks the reader through the installation of the necessary tools and Java itself, and explains how to run (execute) a Java program and the examples of the code provided with this book.
With the basics in place, we then explain and discuss Object-Oriented Programming (OOP) principles, how Java implements them, and how a programmer can take advantage of them to write high-quality code that is easy to maintain.
The book proceeds by presenting a more detailed view of Java as a language. It explains how the code is organized in packages, defines all the main types, and the list of reserved and restricted keywords. All the discussions are illustrated with specific code examples.
This section contains the following chapters:
Chapter 1, Getting Started with Java 12
Chapter 2, Java Object-Oriented Programming (OOP)
Chapter 3, Java Fundamentals
