What This Assignment Is About:
Part 2: (There is no part 1 in this assignment) Programming (20 points)
Your assignment is to create a file called Customer.java containing a class Customer (there is no main method in this class). A Customer has a first name (a String), last name (String), ID number (integer), number of matinee tickets (integer), number of normal tickets (integer), and total cost (double). Each matinee ticket costs $5.00 and each normal ticket costs $7.50. You need to compute the total cost based on the number of matinee tickets and normal tickets.
The class Customer must include the following constructors and methods. (If your class does not contain any of the following methods, points will be deducted.)
Method
Description of the Method
public Customer( )
Default constructor sets the first name and last name to "???", customer ID, the number of matinee tickets, and the number of normal tickets to 0, and the total cost to 0.0.
public Customer (String lname, String fname, int id, int matineeTickets, int normalTickets)
Constructs a Customer object given the last name, first name, customer id, the number of matinee tickets, the number of normal tickets. Its total cost should be updated by calling computeTotalCost( ) method.
public String getFirstName( )
Returns the first name.
public String getLastName()
Returns the last name.
public int getCustomerID()
Return the customer ID.
public int getMatineeTickets( )
Returns the number of matinee tickets
public int getNormalTickets( )
Returns the number of normal tickets.
public double getTotalCost()
Returns the total cost.
public void setFirstName (String fname)
Sets the first name.
public void setLastName (String fname)
Sets the last name.
public void setCustomerID(int id)
Sets the id.
public void setMatineeTickets(int matineeNum)
Sets the number of matinee tickets. Its total cost should be updated by calling computTotalCost( ) method.
public void setNormalTickets(int normalNum)
Sets the number of normal tickets. Its total cost should be updated by calling computeTotalCost( ) method.
public boolean equals (Customer other)
Returns true if the ids and names are the same, return false otherwise.
private void computeTotalCost( )
This is a helper (service) method that computes the total cost based on the number of matinee tickets and normal tickets (Each matinee ticket costs $5.00 and each normal ticket costs $7.50). This method will be called by other methods inside of the class Customer anytime the number of matinee tickets or normal tickets is updated.
public Customer hasMore (Customer other)
Compares the total costs of two customers and returns the Customer who has a higher total cost. If the total costs are same, the first customer (itself) is returned.
public String toString( )
Returns a String with information on each Customer using the following format:
First name: Bill
Last name: Gates
Customer ID: 888777888
Number of Matinee Ticket(s): 0
Number of Normal Ticket(s): 50
Total cost: $375.00
Make use of the NumberFormat class to format the total cost.
Save the Customer class in a file called Customer.java and use the following program stored in Assignment5.java, which has the main method to create new Customer objects and to test your class. A sample output is shown below.
Important Notes: Your class should have exactly the method headers that are described or otherwise your class will not work with the test driver program (Assignment5.java) that is provided. You should never change the test driver program if the test driver is provided but instead make changes to Customer class to make it work.
Helpful hints for doing this assignment:
work on it in steps. Write one method, test it with a test driver and make sure it works before going on to the next method
always make sure your code compiles before you add another method
your methods should be able to be called in any order
After compiling Customer.java file and Assignment5.java file, you need to execute Assignment5 class.
