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.

More operators

We can already add (+), take away (-), multiply (*), divide (/), assign (=), increment (++), and decrement (--) with operators. Let's introduce some more super useful operators, and then we will move straight on to understanding how to use them in Java.

Tip

Don't worry about memorizing every operator shown here. Take a glance at them and their explanations and then quickly move on to the next section. We will put some operators to use soon and they will become much clearer as we look at a few examples of what they allow us to do. They are presented here in a list, just to make the variety and scope of the operators clear from the start. The list will also be more convenient to refer back to when they're not intermingled with the discussion about implementation that follows it.

We use operators to create an expression that is either true or false. We wrap that expression in parentheses like this: (expression goes here). Let's take a look at...
