LEGACY CODE RETREAT

The goal of a Legacy Code Retreat is to practice dealing with the nightmare of every developer (aka Legacy Code) in an environment where errors won't cost your head. So work without pressure and take your time to try out alternatives. And, of course, actively exchange ideas with other software developers. The work object will be a lovingly broken-coded variant of the GitHub Trivia game. The programming language can be freely chosen from the portfolio of JVM languages.

Requirements:
A laptop with Java 8, optional other JVM languages and an IDE (Eclipse, IntelliJ, NetBeans) is required.

  • 6 pm - 8 pm

Introduction to Functional Programming with Java

Functional programming is on everyone's lips at the moment. Since Java 8 and Lambdas, Java users now also have some tools at their disposal to implement functional solutions more comfortably. That's why we want to deal with some of the basics of functional programming and see how they can be used in Java. After this workshop, you will know what a pure function is, why referential transparency is a great concept, what values are, how a functional program can be evaluated and what functional data structures are. Furthermore, we will look at how to write a functional DSL and why this is also very interesting for everyday use.

Requirements:
A laptop with Java 8 or higher, IDE and an editor is required.
