PROJECT INSTRUCTION

The SU21Product Company sales two product models, SU21ProductA and SU21ProductB.

The company asks for the application that helps the company to do some tasks that list in the following menu:

File SaleProductSU21Service_White.java

SU21Product Company – McKINLEY WHITE

-------------------------------------------

1. Sale Product

2. Day Sale Report

3. Month Sale Report.

4. Compare Two Months Report.

0. Exit

After finishing one task, the program should redisplay the menu to allow users to continue using the program to select other task until users select exit to terminate the program

You have to use Object Oriented Programming by providing the data type class and the driver class.

You cannot use any data structure in this project. You have to the objects of data type and at least 3 user-defined functions in the driver class

DATA TYPE CLASS

Class ProductSU21_yourLastName holds the following information:

model(char) : can be ‘A’ or ‘B’

units (int): number of units

unitPrice(float): the price of each product

*provide no-argument constructor, parameterized constructor

*provide accessor methods for getUnits() to return value of units

*provide method getMoney() to return the money: money = unitPrice * units

*provide method toString() return output string in the following format:

Where second information is unit price, third information is number of sold units, the last information is money:

If model is ‘A’ display:

SU21ProductA 219.99 12 2639.88

If model is ‘B’ display:

SU21ProductB 350.99 10 3509.90

DRIVER CLASS:

Class SaleProductSU21Service_yourLastName

First, get current date and start transaction number at 0 then display the menu of tasks.

From the main menu, users select one task by typing number 0 to 4:

Task1: SALE PRODUCT

Display the Product Menu to allow users to select the model to buy by typing a number 0 to 2. After finishing one type, redisplay the Product Menu to allow users continue to buy more products:

-------------------------------------------

1. SU21Product A

2. SU21Product B

0. Exit

Type 1, 2 or 0 to continue:

Type 1: this means users select the SU21ProductA

Type 2: this means users select the SU21ProductB

Type 0: this means users finish and wait for the receipt

When users type 1 or 2: display message to ask for the number of units they want to buy and read the number

If users select a type more than one time, the number of units should be added up with the previous number.

For example, users select 1 then enter 10 units. Then, users select 1 again at the Product menu and enter 5 units. This mean that the users buy 15 units, NOT 5 units.

When users type 0: create the object of SU21ProductA and create the object of SU21ProductB by pass the type and number of units in the objects

*Print out the receipt:

-Before print out the receipt, find the money on SU21ProductA and the money on SU21ProductB by use the object to access the method getMoney()

-calculate the subtotal = money on SU21ProductA + money on SU21ProductB

-calculate the tax amount = subtotal * 8.25%

-calculate the total = subtotal + tax amount

-Transaction number 1 will be display as a string “0001”, next receipt of next transaction will be “0002”, etc.

-The price of SU21ProductA is 219.99 and the price of SU21ProductB is 350.99

-Display the total (6657.14) and display the message to ask for Money Paid (6700.00)to calculate the c

change = money paid - total

*Open output file in append mode name dayFile_MMDDYYY.txt where MMDDYY is d from current date.

Write one line to the file with 3 information separated by one space in the following the close file

Transaction numberOfSU21ProductA numberOfSU21Poduct

Task2: DAY SALE REPORT

Read the date from users in the format MMDDYYYY

Create the file name: dayFile_MMDDYYYY.txt

Check if file does not exist, display message “File does not exist”.

If the file exists, open file to read:

-Each line stores the information of one transaction from Task1.

-For each line, split to get numberA and numberB that are the numbers of units of each product model.

-the add up all these numbers into two sum_numberA and sum_numberB.

-At the end of file, there are sum_numberA and sum_numberB. Create one object of SU21Product of model A and one object of SU21Product of model B

-find the money on SU21ProductA and the money on SU21ProductB by use these objects to access the method getMoney()

-calculate the subtotal = money on SU21ProductA + money on SU21ProductB

-calculate the tax amount = subtotal * 8.25%

-calculate the total = subtotal + tax amount

-print the day report in the following format:

4. COMPARE TWO MONTHS REPORT

-Ask users to provide the first month and the second month that they want to compare in the format MMYYYY

To create the file name monthFile_MMYYYY, for example, monthFile_042021.txt or monthFile_052021.txt

-Check file exists. If one of these two files do not exist, display message “File does not exist”

-If both files exist, open, and read each line, split information and add up number of each product. At the end of

the first file there are numberA1 and nunberB1 that are the number of the model A and the number of the model B. At the end of the second file there are numberA2 and numberB2.

-On each product model, calculate the different between numbers sold from two months:

Different between 2 months of model A = number of model A in 2nd month – number of model A in 1st month

Different between 2 months of model B = number of model B in 2nd month – number of model B in 1st month

-On each product model, calculate the percentage that reference to see how much percentage increasing:

Percentage Increase of model A = 100 * different between 2 month of model A / number of model A in 1st month

Percentage Increase of model B = 100 * different between 2 month of model B / number of model B in 1st month

-Display the report:
