Is there a reason to get the file name of a path before converting it to a file?

Someone answered one of my questions using path.getFileName().toFile() instead of just path.toFile(). Is there a reason for that or should I use just path.toFile()?

Solution

  • In your specific situation it was path.getFileName().toFile().getName() in this case path.toFile().getName() will give you same result.

    But generally speaking path.getFileName().toFile() and path.toFile() will return different files.

    Here small example.

        Path path =  FileSystems.getDefault().getPath("foo", "bar", "buzz");
    System.out.println(path.getFileName().toFile());
    System.out.println(path.toFile());

    Which give us

    buzz
foo\bar\buzz
