The language used throughout this book in Oberon-2, a clean and type-safe language designed at ETH Zürich. However, the emphasis of the book is not on the language but on the concepts of OOP. They can easiliy be transferred to any other object-oriented language. The book is aimed at students of computer science as well as at practitioners who want to gain a perspective on modern software development techniques. Compilers for Oberon-2 as well as the source code of the case study in this book are freely available for several common workstations.
