Note: Materials will be in English, the lectures/tutorials will be taught in German; the written exam will be German (you may answer in English).

Class and Credits (Leistungsnachweis)

Lectures: Not your classic lecture— we’ll work together on concrete problems and their solution. The class will be taught in German, the materials are mostly in English.

Tutorials and assignments: Pairprogramming preferred, BYOD strongly recommended!

Credits: written exam (90’) at the end of the semester.

Additional Materials


  1. Introduction (Mar 18, slides, assignments)

    We’ll talk about software architecture, abstraction, decomposition and good software design. We’ll also review the tools and ressources that you’ll need for this class.

  2. Classes and Interfaces revisited (Mar 18, slides, lecture notes, assignments)

    We look at different types of classes (inner, anonymous, local, static), when to use them, and which visibility for which purpose. Also: @FunctionalInterface and lambda expressions.

  3. Inheritance revisited (Mar 25, slides, lecture notes, assignments)

    We talk about abstract and final classes, (pure) virtual functions and defaults. Also, when (and how) to use abstract base classes, and how the Decorator pattern can be used to add functionality to existing classes.

    No class on Apr 1, seriously.

  4. Mixins, pt. 1; Generics, pt. 1 (Apr 8, slides, lecture notes, assignments)

    After a short digression to Mixins, we dig into the details of how generics work in Java, and how to apply them to data structures and algorithms.

  5. Mixins, pt. 2; Generics, pt. 2 (Apr 15, slides, lecture notes, assignments)

    We’ll review Mixins and see how to use generics to make them stateful. Generics and inheritance need special attention, and will lead us to bounds and wildcards.

  6. Reflection and Annotations (Apr 22, slides, lecture notes, assignments)

    Learn how reflection works in Java, and how they enable annotations by using examples of testing (JUnit5), serialization (gson) and networking (retrofit).

  7. Design patterns, pt. 1 (Apr 29, slides, lecture notes, assignments: JavaFX (recommended) or Android (advanced))

    We begin with a few basic patterns: composite, iterator and observer, and use that to dive into Android and MVC/MVVC.

  8. Design patterns, pt. 2 (May 6, slides, lecture notes, assignments: JavaFX or Android)

    We look at more every-day-patterns: singleton, factory, strategy and command.

    No class on May 13

  9. Design patterns, pt. 3 (May 20, slides, lecture notes, assignments: JavaFX, Android)

    We round up a few more useful patterns: proxy and adapter to make other peoples’ modules fit your needs, and flyweight to save on precious memory in (mostly) graphical apps.

  10. Parallel processing (May 27, slides, lecture notes, assignments: JavaFX, Android)

    Because sometimes, you need to work on more than one thing at a time! We’ll look at threads and how to control and synchronize them.

    No class on Jun 3

  11. Asynchronous programming (Jun 10, slides, lecture notes, assignments: CLI, Android)

    User interfaces often require us to work not only in parallel, but to do so in an asynchronous way. Learn about a better Future for asynchronous or concurrent workloads, and what promise chaining can do for you.

  12. Introduction to functional programming (Jun 17, slides, lecture notes, assignments)

    Leave your imperative and objected oriented programming comfort zone and follow me down the rabbit hole of functional programming. After some theory, we’ll do some basic exercises, including filter, map and forEach.

    No class on Jun 24

  13. Functional programming in Java (Jul 1, slides, lecture notes, assignments)

    We’ll talk about the specifics (and limits) of functional programming in Java. Learn about the classes and interfaces used for Java’s functional parts, and the more sophisticated stream reduction using reduce and collect.

  14. Patterns of modern software architecture (Jul 8, slides)

    We’re wrapping up the semester by talking about patterns of modern software architecture, such as dependency injection or microservices.
