That's a ridiculously extreme example, IME. Having been working with Java for 25+ years, I've never seen anything like that in code written by a shop I worked at, FWIW. And as a corollary I'm about 100% certain that you could find some equivalent extreme case to use as an example to dunk on any language/platform.
this is what we mean by "JavaCulture" - java | JVM really wonderful things but the culture is what sets these things back
Maybe there are still some Java shops out there living like this. But to me, this is a 20 year old outdated notion. shrug
You have worked at some outstanding java shops then! In my experience the article is precisely representative of Java culture even today
