Assessment detailsTaradale Folk Festival (TFF) is a (fictional) biennial arts festival based around the central Victorian township of Taradale. To try and provide scheduling flexibility in case of Covid-19 restrictions, the festival organisers have split the festival program into two types of event: unrestricted open air events requiring a venue pass and indoor events requiring an experience pass. It is hoped that if Covid restrictions prohibit indoor events, the outdoor events could continue since attendees are outdoors and could be spaced out further.Your task is to produce, using standard Java (Java SE), a prototype record keeping system for tracking the events that are on offer and accepting bookings. For this initial proof of concept, the system will be console based.Interviews with two TFF staff are given below: Huy, the General Manager, and Tina, the Ticketing and Front of House Manager. You should analyse the interviews to determine the functional requirements for your program. Your development team manager has provided further requirements. These requirements are set out in the three stages (A, B and C) below. Since each stage elaborates on the previous one, you only need to submit one program the one implementing the highest stage you were able to complete.For each of the stages A, B and C, complete the steps below based on the Double Diamond process: DiscoverGo wide in the form of reading and thinking about the supplied stakeholder requirements. Find out what the current situation is and understand user behaviours and business drivers.Fill in the supplied Discover and Define Word template with a list of different problems that could be solved.DefineFrom your understanding of the overall issues/requirements, narrow down to a single problem and turn that into a problem statement. The problem statement defines what you will develop, and you may start some initial coding to start working out if you can create a solution to the problem you defined.Fill in the supplied Discover and Define Word template with a statement of the single problem you will solve.DevelopStart coding to create an initial prototype and program logic to address the problem. You may create a few different iterations to get to the best prototype. This is a phase for trying ideas out to see if they work.DeliverPick the best prototype from the Develop phase and create the final version of the code, refining and making it work. The aim is to create a minimum viable product (MVP) to address the problem you have identified and defined.

Coding Style/DocumentationYour program must follow the coding and documentation style guide given in the file StyleGuide.pdf, available on the course Canvas under the Assignment 2 link.Stage A Modelling and implementing classes to represent and manage open-air venue eventsYour task here is to discover and define the problem for stage A and then develop a Java program which implements the functional requirements derived from the interviews and instructions given below.Huy TFF General ManagerAs a proof of concept, Id like the prototype at this stage to model outdoor Venue events. Id likethe prototype on start-up to ask what the maximum number of events can be, and then be capable of storing up to that many events (giving an error message if I try to exceed that limit).Ill need to be able to enter details about the event that is being added, be able to display the titles of all events, and be able to display all details of the event I specify. These details are: the event title, description and prices of Adult tickets, Child tickets and Concession tickets. The system should keep track of the total number of tickets sold for each event.My ticketing staff will also need to be able to accept customer bookings and produce confirmation tickets.Tina Ticketing and Front of House ManagerWhen an attendee wishes to book to attend an event, I find out the required event title and how many tickets are required. For each required ticket, I then find out the required ticket type (Adult, Child or Concession), record that another ticket has been sold and prepare a ticket to give to the attendee stating the name of the attendee, the event title, the ticket type and the cost of the ticket.Your development-team manager advises that your program must also meet the following requirements: The program must be console driven (i.e. use Scanner for input). Displayed output must be neatly formatted. ArrayLists, Java Collections Framework or other material not covered in weeks 1..8 cant be used. Your program for this stage should be implemented as two classes:o TffEvent stores and processes information relevant to a TTF venue event, including: The void method displayEvent() for displaying all instance variable values, neatly formatted. The boolean method bookEvent(String ticketType, String name) where ticketType indicates the type of the ticket being booked (Adult, Child or Concession), andname is the name of the attendee. This method should print ticket details and manipulate the count of tickets sold to indicate that a booking has occurred. The

method returns true.o StageA implements the main method. This class collects all user input and uses an array of references to objects of type TffEvent called tffEvents to help implement the functionality of stage A. Your program must use the following array (not ArrayLists) for the following purpose: o tffEvents : a 1D array of TffEvent references. Your program should follow the style guides given in StyleGuide.pdf on the Assignment 2 page. You are expected to adhere to all relevant object-oriented programming guidelines, including: Visibility of instance variables and methods set appropriately Instance variable initialisations carried out in the constructor only No unnecessary accessors (setters) or mutators (getters) only provide methods which will be needed when implementing the application class in this stage Parameter lists in methods should be appropriate to the task the method is performing only accept parameters where a method requires one or more values from the caller to perform its assigned task that it does not already have access to Methods which need to communicate a value or result back to the caller should do by returning the value in question, not by storing it in an instance variable Data classes (i.e. TffEvent) should not prompt for input from the userStage B Implementing refundable indoor experience eventsYour task here is to extend your console-driven Java program to implement the functional requirements derived from the edited interviews and instructions given below.Huy TFF General ManagerIn addition to our outdoor venue events, our festival also hosts indoor experience events. Since they are held indoors, each of these events has their own limit on the total number of tickets. I should be able to enter this information when creating the event, and it should be displayed when displaying the event. Unlike the venue events, experience events should also be refundable.Tina Ticketing and Front of House ManagerI now need to be able to book experience events. Ill need the system to produce an appropriate error message if a booking would exceed the available number of tickets for the event.Attendees can also have their experience booking refunded. This involves them giving me their ticket, from which I obtain the event title to determine the event to refund and I then update the record of the total number of tickets booked for that event. Now this is being automated, Id expect the system to print out a confirmation that the refund has been successful, or an error message if when there has been a problem.

Your development-team manager advises that your program must meet all stage B requirements, with the following changes/additions: A new TffExperienceEvent class must extend the TffEvent class. This new class must implement the requirements of the experience event. TffExperienceEvent overrides boolean method bookEvent(String ticketType, String name).This method should make appropriate use of the super construct. The method should return true if a booking was successfully performed, and false if a booking couldnt be successfully completed. TffExperienceEvent overrides method displayEvent, to print out all information about theTffExperienceEvent. The method should make appropriate use of the super construct. Class StageA should be renamed as StageB and modified to support the requirements of stage B. This class must use the array of references to objects of type tffEvent (called tffEvents) to store references to all TffEvent AND TffExperienceEvent objects in the system, and use these objects and polymorphism appropriately for the functionality of stage B.Stage C Implementing attendee lists for refundable indoor experience eventsYour task here is to extend your console-driven Java program to implement the functional requirements derived from the edited interviews and instructions given below.Huy TFF General ManagerWe need to keep a list of the names of ticket holders for a experience events and the price they paid, so we can verify they hold a ticket and refund the correct amount in case they dont have their ticket available when they claim a refund. Id like the list displayed as part of displaying anexperience event. The ticket holders record should be deleted once they have been refunded.Your development-team manager advises that your program must meet all stage B requirements, with the following changes/additions: Class TffExperienceEvent must utilise a 1D String array instance variable, called bookings, to store ticket booking details (i.e. the name list of ticket holder name and price paid). It can be assumed that a ticket holders name will be unique. Class StageB should be renamed as StageC and modified to support the requirements of stage C. This class must still use the array of references to objects of type tffEvent (called tffEvents) to store references to all TffEvent AND TffExperienceEvent objects in the system, and use these objects and polymorphism appropriately for the functionality of stage C.
