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 1: Getting Started with Java 17

This chapter is about how to start learning Java 17 and Java in general. We will begin with the basics, first explaining what Java is and its main terms, followed by how to install the necessary tools to write and run (execute) a program. In this respect, Java 17 is not much different from the previous Java versions, so this chapter’s content applies to the older versions too.

We will describe and demonstrate all the necessary steps for building and configuring a Java programming environment. This is the bare minimum that should have on your computer to start programming. We also describe the basic Java language constructs and illustrate them with examples that can be executed immediately.

The best way to learn a programming language—or any language, for that matter—is to use it, and this chapter guides readers on how they can do this with Java. We will cover the following topics in this chapter:

  • How to install and run Java
  • How to install and run an integrated development environment (IDE)
  • Java primitive types and operators
  • String types and literals
  • Identifiers (IDs) and variables
  • Java statements
