Java get parent of parent

Question

This is a very similar question to this one: How to get just the parent directory name of a specific file

But there he wanted to get just the closest Parent directory, what I want is to be able to select other "Parents" such as:

bbb or ccc (considering the same example on the mentioned question)

File file = new File("C:/aaa/bbb/ccc/ddd/test.java");

I tried file.getParent().getParent(); which didn't work.

Note: if possible I don't want to use regex on the path.

Answer 1

getParent() returns a String - you can't call getParent() on a String .

Instead, you want getParentFile() :

File grandparent = file.getParentFile().getParentFile();

Answer 2

getParent() returns a String; getParent() returns a File; eg:

Boolean fileNameChangedCheck = file.renameTo(
        new File(filePath.getParentFile(), "changedFileName"));

Here filePath.getParentFile() can't be replaced by filePath.getParent() ;
