  • Library built this way because it supposed to be flexible and provide ground for complex usecases. It can only be flexible if your API works with simple abstractions which you can then compose. It’s not driven by “I need this specific utility for this specific scenario”. That would be zoo you have in JS where you have 10 ways to iterate over array and 9 of them wrong for your scenario.

    Java’s OO is great because they design library with SRP in mind making sure there is few but good ways to do things.

    BufferedReader cannot accept file name because it makes arbitrary reader… well buffered. It’s not BufferedFileReader, even that would accept something like Path or File, not string, because File can be remote file, should Reader now know all possible local and remote protocols and path formats? What else it must do?

    Having it designed the way it is, allows Java to have utilities for various scenarios. Your scenario covered by standard lib too. See Files.readAllLines which, surprise-surprise, built on top of BufferedReader.
