UserPrincipal owner = null;
		
try {
	owner = path.getFileSystem().getUserPrincipalLookupService().lookupPrincipalByName("King");
			
	Files.setOwner(path, owner);
} catch (Exception e) {
	e.printStackTrace();
}

FileOwnerAttributeView.setOwner()

Path path = Paths.get("F:/cn/icer/ws/client/Business.java");
		
UserPrincipal owner = null;
		
FileOwnerAttributeView foav = Files.getFileAttributeView(path, FileOwnerAttributeView.class);
		
try {
	owner = path.getFileSystem().getUserPrincipalLookupService().lookupPrincipalByName("King");
			
	foav.setOwner(owner);
} catch (Exception e) {
