Question

How do I get the directory name for a particular java.io.File on the drive in Java?

For example I have a file called test.java under a directory on my D drive.

I want to return the directory name for this file.

Answer 1

File file = new File("d:/test/test.java");
File parentDir = file.getParentFile(); // to get the parent dir 
String parentDirName = file.getParent(); // to get the parent dir name

Remember, java.io.File represents directories as well as files.
