Overview of this book

Java is one of the most preferred languages among developers. It is 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’ll then focus on understanding object-oriented programming (OOP), with exclusive insights into concepts such as 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 with the help of sample programs and practice examples. You’ll 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 and also build a sample project to help you understand the applications of these concepts. By the end of this Java book, you’ll not only have become well-versed with Java 17 but also gained a perspective into the future of this language and have the skills to code efficiently with best practices.

Chapter 3: Java Fundamentals

This chapter presents to you a more detailed view of Java as a language. It starts with code organization in packages and a description of accessibility levels of classes (interfaces) and their methods and properties (fields). Reference types, as the main types of a Java object-oriented nature, are also presented in detail, followed by a list of reserved and restricted keywords and a discussion of their usage. The chapter ends with the methods of conversion between different primitive types and from a primitive type to a corresponding reference type and back.

These are the fundamental terms and features of the Java language. The importance of understanding them cannot be overstated. Without them, you cannot write any Java program. So, try not to rush through this chapter and make sure you understand everything presented.

The following topics will be covered in this chapter:

  • Packages, importing, and access
  • Java reference types
  • Reserved...
