Problem: Disneyland has begun a service that allows guests at the park to pre-order drinks and pick them up at a

designated time so as to avoid long concession lines. Guests that spend more than $150 (cumulatively) become

preferred customers and are awarded discounts on future orders. A program is needed to track the amount spent

by each customer and promote them to preferred customer when they have accumulated $150 in purchases.

Classes:

Customer (base class)

o Members

First name

Last name

Guest ID

Amount spent

o Methods

Overloaded Constructor

Accessors

Mutators

Preferred Customer (derived class)

o Member

Details:

The price of the drink is determined by the type of drink and the amount of ounces ordered

o The number of ounces ordered and the price per ounce will be given for each order

Each drink will come in a cylindrical container

The container can be personalized with different Disney graphics

The total price of the personalization is determined by the price per square inch of the container

o The radius, height and price per square inch will be given for each input

Preferred customer information and regular customer information will be stored in files and will be read

into memory before the program processes orders.

o Note that the files may be empty or may not exist.

o In both cases, the respective customer array should not be created until a customer reaches

preferred status.

Regular customers and preferred customers will be held in 2 separate arrays.

The arrays are to be no larger than the actual number of members in each category.

Orders will be read from a file.

After processing an order, if a customer has accumulated $150 or more, promote the customer to

preferred status.

o The preferred customer array will be resized to add one more element.

o Add the new preferred customer into the open element at the end of the preferred customer

array.

o Resize the regular customer array and remove the customer data that was promoted to preferred

status.

Preferred customers get a discount based on how much they have spent overall

o $150 = 5% discount

o $200 = 7% discount

o $350 = 10% discount

Input: Input data will be stored in three files: preferred.dat, customers.dat and orders.dat. The total number of

lines in each file will be unknown.

Preferred.dat will hold the data for known preferred customers and customers.dat will hold the data for known

regular customers. Both files should be read at the beginning of the program to establish the preferred customer

and regular customer arrays respectively. The files may be empty or may not exist. In such cases, there should

not be a respective customer array created before reading the orders.

Each line of preferred.dat will be formatted as follows (except for the last line of the file which will not have a

newline character). The data will be listed in the following order on each line with a space between each field.

There will be no invalid data on any line.

customer ID

first name

last name

amount spent

discount

newline

Each line of customer.dat will be formatted as follows (except for the last line of the file which will not have a

newline character). The data will be listed in the following order on each line with a space between each field.

There will be no invalid data on any line.

customer ID

first name

last name

amount spent

newline

Orders.dat will hold all orders to process. Each line of the file will be formatted as follows (except for the last line

of the file which will not have a newline character). The data will be listed in the following order on each line with

a space between each field. There will be no invalid data on any line.

customer ID

container radius

container height

ounces

ounce price

square inch price

quantity

newline

For each order, the main thing to note is the total cost and its connection to the appropriate customer. The total

cost will be added to the amount spent for each customer. If the customer has preferred status, the discounted

price will be added to the amount spent. After the amount spent has been updated, check to see if the customer

has gained preferred status or if the preferred customer qualifies for a larger discount.

When moving a regular customer to the preferred customer array, always add the data to the end of the array.

When removing the customer from the regular customer array, shift the elements toward the front of the array.

Do not rearrange the order of the data in either array. Remember that each array should be no bigger than the

number if elements it needs to hold.

Output: At the end of the program, write the regular customer data and preferred customer data to the

respective files. Use the proper format as listed above in the Input section. There will be no output to the screen.

sample customer :

64297 Mickey Mouse 100.00 217456 Christopher Robin 0.00 26384 Walt Disney 25.73 

sample preffered:

778234 Minnie Mouse 165.50 5% 

sample transaction:

26384 2.5 8 36 .25 .35 1 26384 2.5 10 40 .45 0 2 64297 3.25 12.5 64 .15 .03 10 

FAQ:

Will there be invalid customer IDs in the transaction file?

No. All customer IDs in the transaction file will map to a customer ID in either the customer file or the preferred customer file.

Which files may be empty or not exist?

Only the preferred customer file may not exist or be empty. While the other two files will be there for this project, it is good programming practice to check that all files are present and open properly before trying to process them.

Will the cylinder be closed or open?

The cylinder will be closed. The surface area should be the top, bottom and side of the cylinder.

If a customer meets the threshold to become a referred customer, do we apply the discount to the order that put the customer over the amount?

Discounts should not be applied unless the customer is already at preferred status.

If a preferred customer places an order that puts them at a higher discount level, do we apply the new discount to that transaction?

No, any discount used is equal to the discount held in the preferred customer object before adding to the total. If the total meets the requirements of a larger discount level, apply the old discount, update the total and then assign a new discount if applicable.

Can I build a drink or transaction object (or array of objects)?

You can, but I think that would be inefficient. There is not a need to hold onto the drink information for anything more than a calculation. Creating an object to hold the results of a calculation seems wasteful of your memory.

How do I know if the customer dos not want the container to be personalized?

The price per square inch will be 0 (or 0.0).

THIS IS ALL IN JAVA

IN BOLD ABOVE IS THE PROBLEM/Question
