Welcome to the Wiki of the seminar '''Java vs. C++''' in the winter semester 2010 / 2011

This seminar is given by Prof. Dr. Hannah Bast, assisted by Björn Buchhold(buchholb@informatik.....). The seminar takes place every Wednesday, 2:15 pm - 3:45 pm, in the seminar room 01-018 in building 101. Our first session is on Wednesday, October 20, 2010. The last session is on Wednesday, February 9, 2011. On Wednesday December 29, 2010 and on Wednesday January 5, 2011 there is no session due to the christmas break. That's 15 sessions altogether. All sessions are recorded (video + audio).

The seminar is about the performance differences between Java and C++, in particular, running time and space consumption. It's NOT about the differences in syntax, language features, ease of programming, etc. The sessions will be recorded, and the slides as well the recordings will be put online after each presentation: see the links below.
