A Task based 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.
On the JVM this is a wrapper around
java.nio.file.WatchService
(class available since Java 7 for registering objects for changes and events).
