Although you cannot create an instance of an abstract class, you can declare a variable that is typed by an abstract class:
... Attraction x; ...
The value of such a variable can be either a Movie instance or a
Symphony instance, because the value of a variable declared for a
particular class can be an instance of any subclass:
... x = new Movie(); ... x = new Symphony(); ...
