While Greenfoot is an educational environment, Java is not a toy language. The projects discussed in this book are easy enough that they can be managed by high school students, but they are also open and extendable enough that even seasoned programmers can find interesting and challenging aspects to do. Exercises are worked into the text throughout the book-if you do them all, you will come out of this as a fairly competent programmer. This book can be used both as a self-study book or as a textbook in a programming course. We think we can manage to make the experience interesting and pedagogically sound at the same time. There is no reason why computer programming has to be dry, formal, or boring. The emphasis throughout is to make the work we do interesting, relevant, and enjoyable. We typically follow a spiral approach: We introduce some aspects of a concept when we first encounter it, then revisit it later in another context, and gradually deepen our understanding. Instead of introducing a concept theoretically first, and then doing some exercises with it, we often jump right in and use a construct, initially explaining only as much as necessary to solve the task at hand, then come back to the theoretical background later. This leads to a more hands-on approach to programming than what would be possible without such an environment.Ī more practical approach does not mean that the book does not cover the necessary theory and principles as well. And that does not only mean playing computer games it means playing with programming: we can create objects, move them around on screen, call their methods, observe what they do, all interactively and easily. This is also the reason we use Greenfoot: It is the Greenfoot environment that makes this possible. This is quite different from many introductory programming textbooks which are often structured around programming language constructs.Īs a result, this book starts with less theory, and more practical activity than most programming books. First, there is a problem that we need to solve, then we look at language constructs and strategies that help us solve the problem. Chapters and exercises are structured around real, hands-on development tasks.

However, it will also show you how to make your own computer game, a biology simulation, or an on-screen piano.
While the examples we discuss in this book are specific to the Greenfoot environment, the concepts are general: working through this book will teach you general programming principles in a modern, object-oriented programming language.
There are several goals in doing this: one is to learn programming, another is to have fun along the way. Welcome to Greenfoot! In this book, we will discuss how to program graphical computer programs, such as simulations and games, using the Java Programming Language and the Greenfoot environment.
