You will need to use EventManager.zip to start this assignment text document or You will submit 3 programs Event.java, seatjava and Hw4.javo, and snapshot containing the output for Q1iii) Q1) (80 Points) Imagine you own a Ticketing agency and you handle all the ticketing requirements for different events happening in and around Las Cruces. You have been given an incomplete 'Event class whose states are "Date of the event", "Venue of the event" and "a list of all the seats available for that event". We have used the String data type for "Date" and Venue", and an ArrayList for the "List of Seats. It should be immediately clear that we need a "Seat class to work with the ArrayList. i) (20 Points) So first of all we are going to work with the Seat class. You have been given an incomplete Seat class and your job is to complete all the get (accessors) and set (mutators) methods, and the parameterized constructor within it. (Look for syour code goes here> in the class to add your code:; look for the comments to see what purpose would the method serve.) ii) (50 Points) Once you're done with the Seat class, you would now complete all the methods inside the Event class. (Look for syour code goes here> in the class to add your code; look for the comments to see what purpose would the method serve.) (Hint: Refer to the CarAccountont class provided for Week 3 to get an idea on how you could use the ArrayList and the Seat class to complete all methods in the Event class.) il) (10 Points) Finally, run the program EventManager.java and report the output (you can either copy and paste the output to a text document or attach a snapshot) Note: Make sure to keep your source code as you'll need it on the next homework Q2) (20 Points) Create an enum type Month" that contains all the months in a year (January- December). Now in a class (Hw4), create a "Month type variable MyBirthdayMonth and assign a "Month" entry to it (eg. Month.January or Month.December) depending on which month you were born. Now simply display this "MyBirthdayMonth using a System.out.println() (Hint: We have a similar example in the notes provided for week3)
