I have this abstract class called ticket, and I want other classes to inherit the base value by extending it (atTheDoorTickets would contain the Tickets class) except when I type in public class WalkupTicket extends Ticket { } it gives me an error on WalkupTicket. I know it has something to do with the abstract class because when I delete "abstract" from my ticket class, everything works.
