Scala: Einführung in die praktische Programmierung

Why Scala Stands Out on the JVM

Scala is more than just another JVM language—it’s a carefully designed blend of object-oriented and functional programming that feels familiar to Java developers yet offers significantly more expressive power. This German-language book takes that promise seriously. Instead of racing through syntax, it builds a deep understanding of how Scala’s unique features work together in real projects.

Written by an instructor who switched his own introductory courses from Java to Scala, the material reflects years of classroom experience. The result is a text that respects your existing knowledge while guiding you toward cleaner, more concise code.

From First Steps to Confident Development

The opening chapters walk through environment setup with the tools you already know—Maven, SBT, Eclipse, NetBeans, and IntelliJ IDEA. You’ll see how Scala’s interactive interpreter and compiler work, then move quickly into syntax and imperative programming before exploring pure object orientation with classes, traits, inheritance, and implicits.

Functional programming gets the detailed treatment it deserves. Lazy evaluation, recursion, higher-order functions, case classes, pattern matching, and currying are explained with practical examples. The type system chapter alone will change how you think about static typing, showing how inference, variance, bounds, and self-types catch errors at compile time without drowning you in boilerplate.

Real-World Libraries and Frameworks

The later sections go beyond language features. You’ll learn how to use the standard library effectively, handle XML and parsers, and work with actors for concurrency. Testing is covered with ScalaCheck, ScalaTest, and Specs, so you can build reliable software. The book also introduces three major JVM web frameworks—Lift, Scalatra, and Akka—with hands-on examples like a movie store and a final grade calculator.

Who This Book Is For

If you already work with Java or another object-oriented language and want a rigorous, well-structured introduction to Scala, this book is an excellent fit. It’s also suitable for students and professionals who need to understand functional concepts without abandoning the JVM ecosystem. The German-language presentation makes it especially useful for readers in German-speaking regions, but the code and concepts remain universal.

Expect a practical, thorough journey through one of the most influential JVM languages—and a reference you’ll return to as your Scala projects grow.
