Polyglot programming is the practice of writing code in multiple programming languages, which gives software engineers a much broader choice in terms of software libraries and frameworks they can use for building applications.

In this seminar, students will explore the domain of polyglot programming with focus on the programming experience. For this, they will build novel polyglot applications for different use cases using GraalVM, a high-performance polyglot virtual machine. There will be weekly individual student project meetings (held in German or English) as well as occasional meetings with all groups during the seminar slots (held in German or English) to exchange ideas and present results.


Students should be relatively familiar with at least two of the following programming languages:

  • C, C++, Java, JavaScript, Python, R, Ruby, Smalltalk (in alphabetical order)



The grading will be based on:

  • Participation in discussions (20%)
  • Mid-term presentation (20%)
  • Final presentation (20%)
  • Project work and implementation (40%)


The preliminary schedule is as follows:

9. April 2019 Introduction and project proposal presentations
11. April 2019 Project proposal discussions
16. April 2019 Introduction to GraalVM
