Proper design techniques.

Project Requirements

Your job is to implement a simple amusement park information system that keeps track of admission tickets and merchandise in the gift shop. The information system consists of three classes including a class to model tickets, a class to model gift shop merchandise, the amusement park, and the amusement park tester. The gift shop supports access to specific merchandise in the park’s gift shop and to purchase the merchandise or to order new merchandise for the gift shop. The UML diagram for each class (except the tester class) is given below.

Develop a simple class that models admission tickets. Each admission is described by several instance fields:

A ticket number as a long integer to identify the unique ticket,

A ticket category represented as a String to store the category of the ticket (i.e. adult, child, senior),

A ticket holder represented as a String to store the name of the person who purchased the ticket,

A date represented as a Date to store the admission date for the ticket,

A price represented as a double to store the price of the ticket,

A purchase status represented as a boolean to indicate if the ticket has been purchased (or is reserved).

In addition to these fields, the class has the following constructors and methods:

A parameterized constructor that initializes the attributes of a ticket.

setPrice(double price) to change the price of a textbook.

changePurchaseStatus(boolean newStatus) to change the purchase status of the ticket.

Accessor methods for all instance fields.

toString() to return a neatly formatted string that contains all the information stored in the instance fields.

Develop a simple class that models merchandise available in the gift shop such as t-shirts, sweatshirts, and stuffed animals. The class has several instance fields:

An ID as a long integer to identify the specific merchandise item,

A category as a String to store the specific type of merchandise,

A description as a String to store the description of the merchandise,

A price represented as a double to store the price of the merchandise,

An instock as a boolean to indicate if the merchandise is instock or on- order.

Valid values for category include "T-Shirt", "Sweatshirt", and "Stuffed Animal", as well as any additional category you choose to support. If invalid values are entered, an error message must be printed and the category instance field must be set to "UNKNOWN".

In addition to these attributes, the class has the following constructors and methods:

A parameterized constructor that initializes the attributes of a merchandise item.

setPrice(double price) to change the price of the merchandise.

setInstock(boolean newStatus) to change the status of the merchandise item.

Accessor methods for all instance fields.

toString() to return a neatly formatted string that contains all the information stored in the instance fields.

Develop class AmusementPark that keeps track of tickets and gift shop inventory. The AmusementPark uses two ArrayLists to store Ticket and Merchandise objects. The AmusementPark provides several methods to add merchandise to the gift shop and to access merchandise. The following UML diagram describes the class, the constructor, and the methods:

AmusementPark

-tickets : ArrayList<Ticket> -merchandise : ArrayList<Merchandise> -name : String

+AmusementPark(String) +getName() : String +getTicketDates() : ArrayList<Date> +getTickets(Date date) : int +getTicket(long id) : Ticket +getMerchandise() : ArrayList<Merchandise> +getMerchandise(String category) : ArrayList<Merchandise> +getMerchandise(long id) : Merchandise +addTicket(Ticket) +addMerchandise(Merchandise) +buyMerchandise(String id) +buyTicket(String id)

The class has three instance fields:

name, the name of the bookstore

tickets, an ArrayList<Ticket> storing Ticket objects

merchandise, an ArrayList<Merchandise> storing

Merchandise objects

getName() returns the name of the bookstore.

getTicketDates() returns an ArrayList<Date> of all the dates for which tickets are still available. If there are no tickets available, an empty list is returned.

getTickets (Date date) returns an integer indicating the number of tickets available for the specified date.

getTicket(long id) returns the Ticket that matches the specified id. If there is no Ticket matching the given id, null is returned.

getMerchandise()returns an ArrayList<Merchandise> of all the inventory (in-stock and ordered). This method must create a separate copy of the ArrayList before it returns the list. If there are no merchandise items in the AmusementPark, an empty list is returned.

getMerchandise(String category) returns a list of Merchandise objects whose category matches the specified category. For example, if called with "T-shirt" the method returns all Merchandise objects with the category "T-shirt" as a new list. This method must create a new copy of an ArrayList that stores all the matched Merchandise objects. If no items in the AmusementPark match the given name, an empty list is returned.

getMerchandise(long id) returns the merchandise item that matches the specified id. If there is no merchandise item matching the given id, null is returned.

addTicket(Ticket) adds a new Ticket to the inventory of the

AmusementPark.

addMerchandise(Merchandise) adds a new Merchandise to the inventory of the AmusementPark.

buyMerchandise(String id) removes a Merchandise object from the list of merchandise of the AmusementPark. If the id does not match any Merchandise object in the list, an exception is thrown.

buyTicket(String id) removes a Ticket object from the list of ticket items of the AmusementPark. If the id does not match any Ticket object in the list, an exception is thrown.

Design a tester class called AmusementParkTester. The tester class has a main() method and tests the functionality of the class AmusementPark as follows:

Create AmusementPark and name it "Walden Amusement Park".

Create a minimum of three Ticket objects and add them to the bookstore.
