In the age of digitalization, this book invites readers to learn the fundamental tools of computer programming. Motivating and always understandable for beginners, the authors introduce the key aspects of the Java programming language and the Processing programming environment. Readers learn through graphical examples how to create small games, animations, fractals, or simulations with minimal effort. All examples can be implemented on a laptop. The only requirement is that Processing can be installed and run. Starting from simple building blocks, the book progressively tackles more complex problems, thereby covering the essential concepts of programming. The authors consistently engage their readers with the right words: their detailed descriptions and instructions address the relevant questions directly.
