You can see in the given example that firstly you have to get the specified node using the method userRoot().node("/Roseindia Employees") method.

Here is the code:

import java.util.prefs.*; import java.io.IOException; public class RemoveNode{   public static void main(String[] args)throws IOException, BackingStoreException {   Preferences prefs = Preferences.userRoot().node("/Roseindia Employees");   prefs.removeNode();   }  }
