    The,
    World,
    of,
    Geeks
}
;
  
public class Enum_Set_Demo {
  
    public static void main(String[] args)
    {
  
        // Creating an empty EnumSet
        // Getting all elements from GFG
        EnumSet<GFG> e_set = EnumSet.allOf(GFG.class);
        ;
  
        // Displaying the empty EnumSet
        System.out.println("Initial set: " + e_set);
  
        // Cloning the set
        EnumSet<GFG> final_set = e_set.clone();
  
        // Displaying the final set
        System.out.println("The updated set is:" + final_set);
    }
}
