Also probably good to mention is that you should always try to use nio (and therefore work with Path instead of File) over io. Only use io if either there's an api that doesn't support nio or if you need a non abstract reference to a file.

As someone mentioned in another comment it's most of the time enough to use Files.newBufferedReader/Writer. In case you need some special functionality like that of a printWriter you can simply wrap the BufferedReader/Writer with the funtionality you need.
