alt Hacker NewsIn the early 2000s I often saw juniors and students make staggeringly deep class hierarchies. The equivalent of:
Shape::Polygon::ConvexPolygon::FourSidedConvexPolygon::Square::BlueSquare...
"Intro to OOP" lectures/articles made a deep impression on some people in not quite the right way :)
I was working at that time and never saw this from juniors. Overeager seniors and architecture astronauts, sure. But juniors? They mostly copy pasted code without even taking a second look at the codebase, and without bothering to break functions in any sensible way.
Mind you, I mean enterprise and line of business software, not hobbyists. I also mean of their own volition, not the kind of nonsense that Java frameworks often forced on them (all the patterns under the rainbow, factory abstract method factory of abstract methods).
