Glad to see that university CS education is still deeply confused about the most basic things (this picture is real and comes directly from a former robotics student of mine)

Thinly veiled Java propaganda.

You're not wrong. It sounds like these slides came with a textbook called Absolute Java (by Savitch), and my student just shared the relevant section of the textbook, which is only slightly less wrong, and very Java-brained in concerning ways

My student points out that the blue box at the bottom actually contains a much simpler and more correct definition, at a level of simplicity appropriate to an introductory course. Which makes you wonder why the author has this "binary files are not portable except Java" bullshit.

Makes sense. There is a funny "explanation cliff" that introductory books fall off of often, where they get into describing something like this and quickly realize there is no way to do it correctly in a page or two. So the only choices are to omit it, or do "this kind of thing".

If it's in a textbook, that is significantly worse than some random instructor

So Java fixed files. Got it.

Java destroyed computer science education in many ways
