Learning Java by Building Android Games - Third Edition

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 6: Repeating Blocks of Code with Loops

In this brief chapter, we will learn about Java loops and how they enable us to repeat sections of our code in a controlled manner. Loops in Java take a few different forms and we will learn how to use them all. Throughout the rest of this book, we will put each of them to good use.

In this chapter, we will cover the following topics:

  • Making decisions with Java
  • Some more Java operators
  • While loops
  • Do while loops
  • For loops
  • How to draw the grid lines of the Sub' Hunter game (using loops)

This is the second to last chapter before we complete the first game and move on to a more advanced project.
