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 16: Collections and Enumerations

This chapter will be part practical and part theory. First, we will code and use the Apple class and get our apple spawning ready for dinner. Afterward, we will spend a little time getting to know two new Java concepts, the ArrayList class and enumerations (enum for short). These two new topics will give us the extra knowledge we will need to finish the Snake game (mainly in the Snake class) in the next chapter. In this chapter, we will cover the following topics:

  • Adding graphics to the project
  • Coding and using the Apple class
  • Java Collections and the ArrayList class
  • The enhanced for loop

Let's go ahead with the project.
