WatchService

A watch service that watches registered objects for changes and events.

For example a file manager may use a watch service to monitor a directory for changes so that it can update its display of the list of files when files are created or deleted.

Note if any of the methods, or a stream returned by the stream method, is used after this WatchService has been closed, the operation will die with a ClosedWatchServiceException.
