Overview of this book

Android is one of the most popular mobile operating systems today. It uses the most popular programming language, Java, as one of the primary languages for building apps of all types. Unlike most other Android books, this book doesn’t assume that you have any prior knowledge of Java programming, instead helps you get started with building Android games as a beginner. This new, improved, and updated third edition of Learning Java by Building Android Games helps you to build Android games from scratch. Once you've got to grips with the fundamentals, the difficulty level increases steadily as you explore key Java topics, such as variables, loops, methods, object-oriented programming (OOP), and design patterns while working with up-to-date code and supporting examples. At each stage, you'll be able to test your understanding by implementing the concepts that you’ve learned to develop a game. Toward the end, you’ll build games such as Sub Hunter, Retro Pong, Bullet Hell, Classic Snake, and Scrolling Shooter. By the end of this Java book, you'll not only have a solid understanding of Java and Android basics but will also have developed five cool games for the Android platform.

Chapter 8: Object-Oriented Programming

In this chapter, we will discover that in Java, classes are fundamental to everything. We have already talked about reusing other people's code, specifically Android code, but in this chapter, we will really get to grips with how this works and learn about object-oriented programming as well as how to use it. Here is what is coming up in this chapter:

  • An introduction to object-oriented programming, including encapsulation, inheritance, and polymorphism
  • Writing and using our first, very own class
  • An explanation of encapsulation and how it is our friend
  • Inheritance—a first look and how to take advantage
  • An introduction to polymorphism
  • Static classes
  • Abstract classes and interfaces
  • Starting the next game project—Pong

Let's get started.
