B7 Informatics 2 WS 2021/22

Website of Prof. Dr. Barne Kleinen, Professor for Media Informatics (Bachelor/Master) at HTW Berlin


This course is an introduction to algorithms and data structures. It will be taught in English and German with all written material in English. It will be taught using the Java programming language, but it is not about the language. Mastery of basic Java syntax as taught in Informatik I is assumed. We learned primitive data types, statements and rules, interfaces and classes in Informatik I. We will now be looking at more complex data structures and algorithms which work on these data structures.

In particular we will be concentrating on how to solve (small) problems using a programming language. At the end of the semester there will be an introduction to another Programming Language - e.g. Python - so that you get a feel for the language and learn something about differences in programming languages.

Have a look at how this breaks down on this (tentative) Schedule.

Back to Campus

It seems as if we will be finally back on campus this term - or: you will actually get to be on campus - finally!

Please check the Corona FAQ regularly.

Meetings/Weekly Schedule

The class consists of 2x2h of lectures and 2h of lab. The Lab will be held by Linda Fernsel. Please refer to the LSF for time and location information (link above in the External Links menu).


There will be a tutorial. (More Info to come)

Grades & Exam

As in Informatics 1, there will be a Lab, and there will be an Exam. More details will follow until start of classes.


There’ll be 14 exercises and you’ll have to hand in a lab report for each. All info on the labs can be found on the Labs page.

Examinations for Students who already took Info2

If you already took an Info2 class (with Prof. Zhang or Prof. Weber-Wulff) and completed the lab reports/exercise part there, you can skip the lab reports.

To do so, you have to

  • send an email to the other Professor asking them to send your lab grades to me
  • send me an email asking to accept them (you can do both in one email).

You have to do that at the beginning of the term, within the first or second week. I will individually decide on the terms for grading (e.g., if the labs were graded and counting 50% to the grade I might decide to apply that grading scheme) and you will want to know this decision beforehand.

Whether you attend the lectures or not, is your own decision, but note that the content of Info2 might differ. It’s your responsibility to inform yourself about the topics covered.
