Description
Specifications:
Overview: You will continue the program this semester to maintain the inventory for a store.
Do not forget your headers with @author and @since information.
Requirements: Write and modify the following set of classes (All constructors should
take parameters in the order given and initialize empty sets)::
1. Product
a. Attributes – no change
b. Methods – all methods from Project 01 with following modifications
i. setPrice(price: double): None
1. raises InvalidPriceException if amount is negative
ii. addToInventory(amount: int): None
1. raises InvalidAmountException if amount is negative
iii. purchase(amount: int): double
1. if amount is negative or greater than count, do not change
count and raise InvalidPurchaseException
2. FoodProduct – a child of Product
a. Attributes – no change
b. Methods
i. setCalories(calories: int): None
1. raises InvalidAmountException if calories is negative
3. ClothingProduct – no change
4. Customer
a. Attributes – no change (hint: additional attributes will make this class
easier to implement)
b. Methods
i. addToCart(product: Product, count: int): None
1. Adds the passed product and number to the customer cart
2. For this assignment, it will mean calling the purchase()
method of the Product passed and adding to the receipt
String and totalDue if the purchase is successful
3. If the purchase() method raises an
InvalidPurchaseException, this method catches it and
displays a message to the screen beginning with “ERROR: ”

ii. receipt(): String
1. returns each Product in the cart on a separate line in the
format below
{Product Name} – {Product Price} X {count} … {total for
Product}
Total Due – {Total amount}
iii. getTotalDue(): double – returns the total amount due
iv. pay(amount: double): double
1. If amount is greater than or equal to total due, displays a
“Thank you” message to the screen and returns the
amount that should be given as change
2. If amount is less than total due, raises a
NotEnoughPaymentException
5. ClubCustomer – no change
6. Store
a. Attributes
i. An array or Arraylist of ClubCustomer objects
ii. An array or Arraylist of Product objects
b. Methods
i. Constructor no longer takes number for the array. The size set of
Products and ClubCustomers will now be dynamic
ii. getCount(): int – returns the number of Products saved
iii. addProduct(product: Product): None
1. Adds the passed Product to the set
iv. addCustomer(customer: ClubCustomer): None
1. Adds the passed Customer to the set
v. getProduct(name: String): Product
1. returns the Product with the name passed
2. if the name is not found in the set, raises an
ProductNotFoundException
vi. getCustomer(phone: String): ClubCustomer
1. returns the ClubCustomer with the phone number passed
2. if the phone number is not found in the set, raises an
CustomerNotFoundException
vii. removeProduct(name: String): None
1. removes the Product with the name passed from the set
2. if the name is not found in the set, raises an
ProductNotFoundException
viii. removeCustomer(phone: String): None
1. removes the ClubCustomer with the phone number passed
from the set
2. if the phone number is not found in the set, raises an
CustomerNotFoundException

7. Custom Exceptions (All must be instances of RunTimeException)
a. InvalidPriceException
i. Additional Attribute – price: double
ii. toString() “InvalidPriceException: “ + price
b. InvalidAmountException
i. Additional Attribute – amount: int
ii. toString() “InvalidAmountException: “ + amount
c. InvalidPurchaseException
i. Additional Attributes – amount: int, remaining: int
ii. toString() “InvalidPurchaseException: “ + amount + “ requested, “ +
remaining + “ remaining”
d. NotEnoughPaymentException
i. Additional Attributes – amount: double, due: double
ii. toString() “NonEnoughPaymentException: “ + due + “ due, but only
“ + amount + “ given”
e. ProductNotFoundException
i. Additional Attribute – name: String
ii. toString() “ProductNotFoundException: “ + name
f. CustomerNotFoundException
i. Additional Attribute – phone: String
ii. toString() “CustomerNotFoundException: “ + phone
Design: Your program does not require a main method. You are only responsible for
creating the six (6) classes and six (6) Exceptions described above.
Code: The file you submit will be named Assignment02_{StudentNumber}. You should
put all java classes for this assignment inside of this file as discussed in class.
Test: You are responsible for testing your program. It is important to not rely solely on
the examples presented in this Assignment description. It would be a very good idea to
write your own test cases for this assignment.
Grading:
Google Classroom Submission: If anything is ambiguous, it is your responsibility to ask
questions. It is also your responsibility to complete this assignment in a timely manner.
Questions regarding this assignment will likely not be answered if received after 17:00 on
the due date of the assignment.

An example main() method.
Compiler error
Commenting out compiler error gets first Runtime error (“fp.purchase(200)”)
