Question

How can we delete all files in a directory?

(a) Files.delete(path)

(b) Files.deleteDir()

(c) Directory.delete()

(d) Directory.delete(path)

I have been asked this question in a job interview.

My question is from File and Directory topic in division Autoboxing & Miscellaneous of Java

Answer 1

The correct option is (a) Files.delete(path)

Easy explanation: The delete(Path) method deletes the file or throws an exception if the deletion fails. If file does not exist a NoSuchFileException is thrown.
