> I have seen the same problem solved in different languages take 2-3x the amount of work and have a large difference in ongoing maintenance costs I am sure none of this experiences were basis for an objective experience, there are too many variables. But surely, there are (very few) problems that doesn’t fit Java too well, though it is not an OOP-only language, it is a multi-paradigm one, with many FP concepts seeping into it. E.g. for some ultra low-lat audio processing I wouldn’t choose it, your binary stream processing may be another good example, though it depends on a bunch of factors and in many cases java is more than fine for that as well.
