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 12: Handling Lots of Data with Arrays

In this chapter, we will first get the Bullet Hell project set up and ready to roll with a single bullet whizzing across the screen. Then we will learn about Java arrays, which allow us to manipulate a potentially huge amount of data in an organized and efficient manner.

Once we are comfortable handling arrays of data, we will see how we can spawn hundreds or thousands of our new Bullet class instances, without breaking a sweat.

The topics in this chapter are as follows:

  • Planning the Bullet Hell game
  • Coding the Bullet Hell engine based on our Pong engine
  • Coding the Bullet class and spawning a bullet
  • Java arrays
  • Spawning thousands of bullets

Let's plan what the final game will be like.
