Given the following code for monitoring a directory:         

Path path = Paths.get(directoryPath);         
WatchService watchService = FileSystems.getDefault().newWatchService();         path.register(watchService, StandardWatchEventKinds.ENTRY_CREATE,                         StandardWatchEventKinds.ENTRY_MODIFY,
                        StandardWatchEventKinds.ENTRY_DELETE);         

while(true){             
WatchKey key = watchService.take(); //waits until a key is available          
System.out.println(key.isValid());                         

 for (WatchEvent<?> watchEvent : key.pollEvents())             {               
 Kind<?> kind = watchEvent.kind();                
System.out.println(kind);             }         }

A file is created and then deleted from the monitored directory.

You are right. It should be System.out.println(watchEvent); instead of System.out.println(kind); Fixed.
