Final answer:
To monitor the contents of a directory using Java, you can use the WatchService class from the Java NIO package.
Step-by-step explanation:
To monitor the contents of a directory and display the changes using Java, you can use the WatchService class provided by the Java NIO package.
Here is an example of how to implement this:
- Create a new thread that will run in the background and continuously monitor the directory using the WatchService.
- Set up a loop inside the thread to check for changes every second. If any changes are detected, get the list of events and display the contents of the directory.
- To start monitoring the directory, invoke the 'register' method of the WatchService with the StandardWatchEventKinds.ENTRY_CREATE, StandardWatchEventKinds.ENTRY_DELETE, and StandardWatchEventKinds.ENTRY_MODIFY event types.
