public class OwnerOfFile {
  public static void main(String[] args) throws Exception {
    // create object of scanner.
    Scanner KB = new Scanner(System.in);

    // enter path here.
    System.out.print("Enter the file path : ");
    String A = KB.next();
    Path path = Paths.get(A);

    // create object of file attribute.
    FileOwnerAttributeView view = Files.getFileAttributeView(path,
      FileOwnerAttributeView.class);

    // this will get the owner information.
    UserPrincipal userPrincipal = view.getOwner();
