> what do generics have to do with making it longer?

Code duplication, just one example: https://godoc.org/github.com/cznic/mathutil#Max

Even with exception handling code, Java is shorter. Build scripts are not part of this discussion.

Except Java's method that does the same (Math.max) does not use generics and instead has overloads for the various numeric types it supports.
