[SOLVED] Comp1406 – assignment 2

In this assignment, you will create 3 objects and get them to interact together.
Specifically, you will create a TicketBooth object in which Person objects will
purchase tickets in order to get onto Rides.You will define these classes,
then do testing which simulates many people buying tickets and getting on the
rides. The testing will then compute additional information about the rides and ticket booth.Define a class called Ride that defines the following attributes:
• name – a string indicating the name of the ride
• ticketsRequired – int indicating the number of tickets
that must be used to get onto this ride• heightRequirement – float indicating minimum height
requirement for a person to be allowed on this ride
• numberOfRiders – int indicating the number of riders on
the ride so farWrite a constructor that takes as parameters the name of the ride, # of tickets
required and height requirement. Also, write a zero-parameter constructor. Lastly, write a
toString() method that returns a string in the following format:Roller Coaster requiring 6 tickets with a height restriction of 4.9′NOTE: You DO NOT need to make private attributes, nor get/set methods for this assignment.
Write a test program called RideTestProgram.java that creates two rides using the 3-parameter
constructor and one ride using the 0-parameter constructor and then displays the rides to the
console. Run your code to make sure that it works.Define a class called TicketBooth that defines the following attributes:
• moneyMade – a float indicating the amount of money received by
this booth so far
• availablePasses – an int indicating the number of passes that are
available at this booth• availableTickets – an int indicating the number of tickets that are
available at this booth
Define the following two static constants in the TicketBooth class:
• TICKET_PRICE – the price for each individual ticket … set it to be $0.50.
• PASS_PRICE – the price for a ride pass … set it to be $16.50.Write a zero-parameter constructor as well as one that takes an initial # of passes that the booth
has available. Also, write a constructor that takes an initial number of passes that the booth has
available as well as the number of tickets that it has available. So … you will write 3 constructors
altogether. Lastly, write a toString() method that returns a string with the following format:
Ticket booth with 5 passes and 28 ticketsMaking use of the two class constants above whenever possible, write these 2 methods:
• a sellPass() method that simulates the selling of a ride pass at this booth (Hint: Think of
what happens in real life and then determine how the TicketBooth object changes as a
result of this method. Make sure to handle the situation where there are no passes
available).• a sellTickets(int num) method that simulates the selling of the specified number of tickets
at this booth. If there are not enough tickets to accommodate the requested amount then
nothing happens, no selling takes place. (Hint: Think the same way as you did above).Test your code with this program called TicketBoothTestProgram.java:
public class TicketBoothTestProgram {
public static void main(String args[]) {
TicketBooth booth1, booth2;booth1 = new TicketBooth(5, 50);
booth2 = new TicketBooth(1, 10);System.out.println(“Here are the booths at the start:”);
System.out.println(” ” + booth1);
System.out.println(” ” + booth2);// Simulate selling 2 passes, 5 tickets, 12 tickets and 3 tickets from booth1
booth1.sellPass();
booth1.sellPass();
booth1.sellTickets(5);
booth1.sellTickets(12);
booth1.sellTickets(3);// Simulate selling 2 passes, 5 tickets, 12 tickets and 3 tickets from booth2
booth2.sellPass();
booth2.sellPass();
booth2.sellTickets(5);
booth2.sellTickets(12);
booth2.sellTickets(3);// Make sure that it all worked
System.out.println(“
Booth 1 has made $” + booth1.moneyMade);
System.out.println(“Booth 2 has made $” + booth2.moneyMade);
System.out.println(“
Here are the booths at the end:”);
System.out.println(” ” + booth1);
System.out.println(” ” + booth2);
}
}
The code should produce the following output exactly:
Here are the booths at the start:
Ticket booth with 5 passes and 50 tickets
Ticket booth with 1 passes and 10 tickets
Booth 1 has made $43.0
Booth 2 has made $20.5
Here are the booths at the end:
Ticket booth with 3 passes and 30 tickets
Ticket booth with 0 passes and 2 ticketsDefine a class called Person which has attributes called height , money ,
ticketCount and hasPass.The money and height variables are floats representing the amount of
money the person currently has and the person’s height (in inches).
The ticketCount is an integer indicating the number of tickets the person
currently has and hasPass is a boolean indicating whether or not the
person has a pass to get on the rides (assume a person can have at most 1
pass).Write a constructor & all necessary methods in the Person class so that the
following code produces the output as shown below:
public class PersonTester {
public static void main(String args[]) {
Person mary;mary = new Person(4.9f, 20.00f);
System.out.println(mary.height);
System.out.println(mary.money);
System.out.println(mary.ticketCount);
System.out.println(mary.hasPass);
System.out.println(mary); // Notice the money is properly formatted
mary.ticketCount = 3;
System.out.println(mary);
mary.useTickets(2); // You have to write this method
System.out.println(mary);
mary.hasPass = true;
System.out.println(mary);
}
}
Here is the output that your program MUST produce:
4.9
20.0
0
false
4.9′ person with $20.00 and 0 tickets
4.9′ person with $20.00 and 3 tickets
4.9′ person with $20.00 and 1 tickets
4.9′ person with $20.00 and a pass
Make sure to test your class with the test code above BEFORE you continue.Add the following instance methods to the Person class:
• buyPass(TicketBooth booth) – This method simulates the person
buying a ride pass from the given booth object. It should
modify the person and the booth in the appropriate way, and
then return a boolean indicating whether or not the transaction
was successful.The transaction is successful ONLY if the
booth has a pass available AND the person has enough money
for the pass.• buyTickets(int number, TicketBooth booth) – This method simulates
the person attempting to buy the specified number of tickets
from the given booth object. It should modify the person and
the booth in the appropriate way. If the booth does not have
the specified number of tickets available, then the number of
tickets to be sold should be reduced to the number of remaining
tickets available.Then, if the person has enough money to buy the resulting number of tickets
(i.e., either the requested amount or the reduced amount) then the purchase is made. If the
person does not have enough money to buy the tickets, then the number of tickets sold should
be further reduced to the number of tickets that the person can afford. The method must
return an integer representing the number of tickets actually sold. Make sure that the booth
maintains a proper total of all money paid to it.• allowedToRide(Ride aRide) – This method determines whether or not the person is allowed to ride
on the given ride. A person can get on a ride if he/she meets the ride’s minimum height
requirements AND the person either has a pass OR the required number of tickets for that
ride. The method MUST return a boolean and MUST NOT have any System.out.println code
within it. Also, it MUST be written efficiently … you will lose marks for unnecessary code …
make use of any methods you already have.• getOn(Ride aRide) – This method simulates the person getting on the given ride. A person can
get on a ride ONLY if he/she is allowed to (i.e., make sure you use the method you just wrote).
Make sure that the Person AND the Ride object are updated accordingly (no tickets are used
if the person has a pass). The method MUST NOT have any System.out.println code within it
and it should return true if the person was able to get on the ride and false otherwise.Make sure to now test your code with the following test case in a class called FairTester:
public class FairTester {
public static void main(String args[]) {
Ride coaster, ferris, merryGo, tosser;
Person billy, donna, fredy, harry, larry;
TicketBooth booth;
// Make some rides on which people can ride, specify name, #tickets & height req

ferris = new Ride(“Ferris Wheel”, 5, 3.1f);
merryGo = new Ride(“Merry-Go-Round”, 2, 0);
tosser = new Ride(“Tummy Tosser”, 7, 4.9f);// Make a booth, specifiying the number of available passes and tickets
booth = new TicketBooth(4, 100);// Make some people by specifying their height and their money amounts
billy = new Person(4.9f, 10.00f);
donna = new Person(3.0f, 5.00f);
fredy = new Person(6.0f, 0.00f);

System.out.println(“Larry is attempting to go on the ” + merryGo);
System.out.println(“Larry got on: ” + larry.getOn(merryGo));
