I have a file path like this:
/home/Dara/Desktop/foo/bar/baz/qux/file.txt
In Java, I would like to be able to get the top two folders. Ie. baz/qux
regardless of file path length or operating system (File path separators such as /
:
and \
). I have tried to use the subpath()
method in Paths
but I can't seem to find a generic way to get the length of the file path.
Not yet pretty, however, you guess the direction:
File parent = file.getParentFile();
File parent2 = parent.getParentFile();
parent2.getName() + System.getProperty("path.separator") + parent.getName()
Another option:
final int len = path.getNameCount();
path.subpath(len - 3, len - 1)
Edit: You should either check len or catch the IllegalArgumentException
to make your code more robust.
