We did a programming lab in class . . . before we started, I mentioned several times that Java code that would be useful for the lab was posted on the class website.
So it surprised me that several groups got stuck during the lab when they got to the part where the sample code would have been useful because they didn’t go to the website and download the sample code.
Going forward, I will preface important announcements by saying “I cannot emphasize this strongly enough . . .” while pounding my fist on a solid object.
