Somehow it doesn't seem to be such a big problem in Java land. I think there's some common baseline shared by basically everyone - I don't remember ever seeing Java classes which were not indented with 4 spaces for example.

Yeah, this dates back pretty far: https://www.oracle.com/technetwork/java/codeconventions-1500...

While minor variations exist, virtually all Java code follows these conventions pretty closely.

Although I'll note it seems to get a bit more chaotic with regards to indenting newer constructions like streams and lambdas.

People like to pooh pooh Java in the circles I hang out in, but I’m always quick to point out stuff like this, things that are just basically mostly solved in Java land and no one really wastes time on anymore because some pretty good decisions were made 20-25 years ago. How to handle a lot of aspects of dependencies is another classic example.

Auto-formatting is also used for enforcing a line width limit while keeping the code readable, which is hard and tedious to do manually.
