Trimming a directory path String

I have a String file path 

String filePath = "/tmp/test/save/data/java/"

and would like to remove the last 2 directories and last / so that,

String filePath = "/tmp/test/save"

I don't want to create a substring removing the last 10 characters, as the directories might change in length.
I was thinking about doing a combination of split (setting a limit and removing the final index), then join to recreate the string with / seperators, but wondering if there's a cleaner way ?

Solution

  • You could use java.nio.file.Path#getParent.

    String result = Paths.get("/tmp/test/save/data/java/").getParent()
                  .getParent().toString();
