Question

Need help to create general class

Classes Data Element - Ticket Create an abstract class called Ticket with: two abstract methods called calculateTicketPrice which returns a double and getld0 which returns an int instance variables (one of them is an object of the enumerated type Format) which are common to all the subclasses of Ticket toString method, getters and setters and at least 2 constructors, one of the constructors must be the default (no-arg) constructor. . Data Element - subclasses of Ticket Create the following classes for the 4 types of tickets: Adult, Child, Employee, MeviePass. may contain additional instance variables appropriate for the type of ticket. They will extend from Ticket and define the calculateTicketPrice and getld methods. The Adult and Child classes do not require an id, so getId will return a -1. There should be getters and setters for the instance variables, and any other methods that are needed for your design. The .toString method and constructors for these classes will use the super reference to take advantage of the Ticket constructor and toString methods. Use finals to represent constants.
