Description
In this assignment, you will create 5 objects and get them to interact together.
You will create theatres for which patrons will buy tickets from a box office to
watch movies.
(1) The Movie, Ticket, Theatre and Patron Classes
You will need to define 4 objects as indicated below. You must choose appropriate attribute names
so that the test program that follows compiles and runs properly.
• Define a class called Movie that maintains the title of a movie as well as the amount of
earnings it has made since it opened at the theatre.
• Define a class called Theatre that keeps track of the Movie object that is currently playing in
that theatre. A theatre should also have a seat capacity and keep track of how many seats
have been sold for the movie playing.
• Define a class called Ticket that represents a ticket to go and watch a movie. Each ticket is
only valid for a specific Theatre object.
• Define a class called Patron that keeps track of the age of a person as well as the Ticket
object that he/she has purchased.
Write any necessary code so that the following test program works as indicated in the output that
follows:
public class TestProgram {
public static void main(String args[]) {
Movie m = new Movie(“Despicable Me 3”);
System.out.println(m.title);
System.out.println(m.earnings);
Theatre theatre = new Theatre(3);
System.out.println(theatre.capacity);
System.out.println(theatre.seatsSold);
theatre.moviePlaying = m;
Patron mary = new Patron(15);
System.out.println(mary.age);
System.out.println(mary.ticket);
mary.ticket = new Ticket(theatre);
System.out.println(mary.ticket.theatre.moviePlaying.title);
}
}
Despicable Me 3
The expected output is shown here on the right 0.0
Make sure that your code works before you continue. 3

Despicable Me 3
(2) The BoxOffice Class
Define a class called BoxOffice that keeps track of two theatres for which it sells movie tickets. The
cost of a movie ticket is $6.25 for children under 12 years old, $5.75 for adults 65 years old or more
and $12.50 for everyone else. The box office should also keep track of the movie that has made the
most money in the past.
Carefully examine the test program below. Understand how it is supposed to work. Then write the
necessary methods so that the code runs properly, producing the correct results. You may NOT
alter the test program … the TA will be using it to test your code. Note that when tickets are sold to
patrons, the title of the movie is provided. You will need to determine which theatre that movie is
playing in. As a hint, you can compare two strings using the .equals() method in JAVA as follows:
String s1 = …;
String s2 = …;
if (s1.equals(s2))
…;
else
…;
Note as well in the program below that the bestMovie() will either be a previous movie that had the
most earnings or one of the current playing movies … whichever has the most earnings.
Here is the test program:
public class BoxOfficeTestProgram {
public static void main(String args[]) {
// Create a box office with two theatres, each with a capacity of 5 seats
BoxOffice box = new BoxOffice(5, 5);
// Open up a couple of new movies at the box office
System.out.println(“Theatre A opens movie: Justice League”);
box.openMovie(“Justice League”, box.theatreA);
System.out.println(“Theatre B opens movie: Geostorm”);
box.openMovie(“Geostorm”, box.theatreB);
// Now create some patrons
Patron p1, p2, p3, p4, p5, p6, p7, p8, p9, p10, p11, p12;
p1 = new Patron(15);
p2 = new Patron(26);
p3 = new Patron(7);
p4 = new Patron(72);
p5 = new Patron(65);
p6 = new Patron(11);
p7 = new Patron(19);
p8 = new Patron(17);
p9 = new Patron(12);
p10 = new Patron(14);
p11 = new Patron(13);
p12 = new Patron(16);
// … continued on the next page … //
// Sell some tickets to the patrons
System.out.println(“Patron 1 buys ticket for Justice League”);
box.sellTicket(p1, “Justice League”);
System.out.println(“Patrons 2,3 and 4 buy tickets for Geostorm”);
box.sellTicket(p2, “Geostorm”);
box.sellTicket(p3, “Geostorm”);
box.sellTicket(p4, “Geostorm”);
System.out.println(“Geostorm seats remaining: ” +
(box.theatreB.capacity – box.theatreB.seatsSold));
System.out.println(“\nPatron 5 buys ticket for The Giggling Giraffe”);
box.sellTicket(p5, “The Giggling Giraffe”);
System.out.println(“\nPatrons 6 and 9 buy tickets to see Geostorm”);
box.sellTicket(p6, “Geostorm”);
box.sellTicket(p9, “Geostorm”);
System.out.println(“Patrons 7,8,10 buy tickets for Justice League”);
box.sellTicket(p7, “Justice League”);
box.sellTicket(p8, “Justice League”);
box.sellTicket(p10, “Justice League”);
System.out.println(“Patron 11 tries to buy tickets for Geostorm”);
box.sellTicket(p11, “Geostorm”);
System.out.println(“Geostorm sold out ? ” + box.theatreB.isFull());
System.out.println(“\nPatrons 2, 6 and 10 return tickets”);
box.returnTicket(p2);
box.returnTicket(p6);
box.returnTicket(p10);
System.out.println(“\nPatron 10 tries to return a ticket again”);
box.returnTicket(p10);
System.out.println(“Geostorm sold out ? ” + box.theatreB.isFull());
System.out.println(“Geostorm seats remaining: ” +
(box.theatreB.capacity – box.theatreB.seatsSold));
System.out.println(“\nPatrons 11 and 12 buy tickets for Geostorm”);
box.sellTicket(p11, “Geostorm”);
box.sellTicket(p12, “Geostorm”);
System.out.println(“\nBest movie title: ” + box.bestMovie().title);
System.out.println(“Best movie earnings: ” + box.bestMovie().earnings);
System.out.println(“\nTheatre A opens movie: Despicable Me 3”);
box.openMovie(“Despicable Me 3”, box.theatreA);
System.out.println(“Patrons 1,2,7,8,12 buy tickets for Despicable Me 3”);
box.sellTicket(p1, “Despicable Me 3”);
box.sellTicket(p2, “Despicable Me 3”);
box.sellTicket(p7, “Despicable Me 3”);
box.sellTicket(p8, “Despicable Me 3”);
box.sellTicket(p12, “Despicable Me 3”);
System.out.println(“\nBest movie title: ” + box.bestMovie().title);
System.out.println(“Best movie earnings: ” + box.bestMovie().earnings);
}
}
Here is the expected output (make sure that your code works before you continue):
Theatre A opens movie: Justice League

Patrons 7, 8 and 10 buy tickets to see Justice League
Patron 11 tries to buy tickets to see Geostorm
Movie is sold out
Geostorm sold out ? true
Patrons 2, 6 and 10 return tickets
Patron 10 tries to return a ticket again
Patron does not have a ticket
Geostorm sold out ? false
Geostorm seats remaining: 2
Patrons 11 and 12 buy tickets to see Geostorm
Best movie title: Geostorm
Best movie earnings: 49.5
Theatre A opens movie: Despicable Me 3
