Given a file and we have to get, print the file's owner name.

Following packages are using here, to implement this program,

  • java.nio.file.*
  • java.nio.file.attribute.*

There are following two important classes, which are using this program to get the file's owner name.

  • FileOwnerAttributeView
  • UserPrincipal

The method getOwner() gives the owner's name to the object of UserPrincipal class, which can be accessed through getName() method.
