This textbook covers the fundamentals of compiler construction, from lexical analysis and syntax analysis to semantic processing and code generation. As a running example, a compiler for a simple Java-like programming language (MicroJava) is described and developed. It generates executable bytecode similar to Java bytecode. Other topics include the description of translation processes using attributed grammars and the use of a compiler generator to automatically generate the core parts of a compiler. For syntax analysis, the book concentrates on top-down parsing using recursive descent, but also describes bottom-up parsing. All code examples are presented in Java. A companion web page contains a full set of Powerpoint slides for an introductory compiler course, sample solutions for more than 70 exercises provided at the end of each chapter to practice and reinforce the content of that chapter, and the full source code of the MicroJava compiler as well as other code samples. In addition, the open-source compiler generator Coco/R described in the book is provided as an executable and in source code. The book targets both students of Computer Science or related fields as well as practitioners who want to apply basic compiling techniques in their daily work, e.g., when crafting software tools. It can be used as a textbook for an introductory compiler course on which more advanced courses on compiler optimizations can be based.

Der Autor fuhrt den Leser von den Grundlagen objektorientierter Programmierung uber Entwurfs- und Codierungstechniken hin zu einer realistischen Fallstudie in Form eines objektorientierten Fenstersystems mit Text- und Grafikeditor. In UML-Notation wird gezeigt, wofur sich objektorientierte Programmierung eignet und welche Probleme man mit ihr loesen kann. Als Programmiersprache wird Oberon-2 verwendet, ein moderner Nachfolger von Pascal. Die dritte Auflage enthalt neue Kapitel uber Entwurfsmuster und Kontrakte, ein erweitertes Kapitel uber Frameworks sowie ein Glossar.Die beigefugte CD-ROM enthalt Oberon-2-Compiler fur Windows 95/NT, PowerMac und LINUX. Weitere Oberon-2-Compiler sind von der ETH Zurich erhaltlich.

Without a doubt the idea of object-oriented programming has brought some motion into the field of programming methodology and enlarged the set of programming languages. Object-oriented programming is nothing new-it first arose in the sixties. The motivation came from the simulation of discrete event systems. The concept first manifested itself in the language Simula 67. It took nearly two decades for the method to gain impetus, and today object-oriented programming is an important concept and a powerful technique. Meanwhile, we can even speak of an over­ reaction, for the concept has become a buzzword. But buzzwords always appear where there is the hope of exploiting ill-informed clients because they see the new approach as the solution to all their problems. Thus object-oriented programming is often hailed as a panacea. And so the question is justified: What is really behind it? To let the cat out of the bag: There is more to object-oriented programming than merely putting data as objects in the fore­ ground, instead of algorithms to which the data are subject. It is more than purely an alternative view of programmed systems. To identify the essence of object-oriented programming, is the subject of this book. This is a textbook that shows in a didactically skillful way which concepts and constructs are new, where they can be employed reasonably, and what advantages they offer. For, not all programs are automatically improved by merely recasting them in an object-oriented style.
