Best way to get a sub-path of a file

Question

I have two File objects:

1. C:/basepath/
2. C:/basepath/directory/file.txt

Now I would like to subtract file 1 from file 2 so that I get directory/file.txt.
I don't want to use String.substring() since file paths may differ from input.

Answer 1

Use the features of java.nio.file.Path. You are looking to 'relativize'.
