Write a Java Program that emulates an online shopping.

There are fifteen different items in three different categories for sale, and each item with item code, item name, item description, and unit price.

The input file is provided CSV format as shown:

Item Code Item Name Item Description Unit Price

E$001$ Laptop $14-$inch display $8$GB RAM $256$GB S$1200$

E$002$ Smartphone$6\mathrm{.}5-$inch display $128$GB storage $800$

E$003$ Tablet $10-$inch display $64$GB storage $300$

E$004$ Monitor $24-$inch Full HD display $150$

E$005$ Keyboard Mechanical keyboard with RGB light $80$

F$001$ Sofa $3-$seater sofa $500$

F$002$ Dining TableWooden dining table $6350$

F$003$ Chair Ergonomic office chair $120$

F$004$ Bed Queen size bed $600$

F$005$ Bookshelf $5-$tier bookshelf $100$

C$001$ Running ShoesLightweight running shoes $70$

C$002$ T$-$shirt Cotton T$-$shirt $20$

C$003$ Jeans Denim jeans $50$

Item codes that start with E does not have $6\%$ sales tax.

Item Code,Item Name,Item Description,Unit Price $($$$)$

E$001,$Laptop,"$14-$inch display, $8$GB RAM, $256$GB SSD$",1200$

The program must have at least two classes or more: Item and OnlineSale.

The Item class is for the item data with four attributes: itemCode, itemName, itemDescription, and unitPrice.

You are encouraged to include more classes.

Make the main class OnlineSale. The following shows a sample run:

Welcome to MyLastName online sale system!

Beginning a new sale $($Y$/$N$)$ y ;both the upper and lower case should work

$--------------------$

Enter product code: C$0001$ ;the user input stays right to the message

item name: Running Shoes

Enter quantity: $1$

item total: $ $70\mathrm{.}00$ ;the output should be aligned properly

Enter Product code: C$004$

Total with Tax $(6\%)$ $ $266,00$

$----------------------------$

Beginning a new sale $($Y$/$N$)$ N

The total sale for the day is $ $446\mathrm{.}20$

Thanks for using MyLastName$$s online sale system. Goodbye!

$($The example provided must run exact$)$

In the sample run, the bold face letters are output from the sale system and non$-$bold italicized

letters are input from the user. The user enters $-1$ to terminate each current sale. The system is

terminated if the user enters $\text{'}$N$\text{'}$ on Beginning a new sale $($Y$/$N$).$ Then, the system prints out

the total sale amount of the day.

Your program should compile and run in the command line environment. All user input needs to be checked properly to avoid exceptions.

Suggestions: Provide methods $($or functions$)$ that perform the following tasks:

$$ Read item data into items array

$$ Accepts the item code for each item for sale

$$ Get the item name from the item code and print the name

$$ Accepts the quantity of the item

$$ Computes the item total for each item

$$ Get the subtotal of all items purchased

$$ Computes the total sales amount with tax

$$ Initialize the item purchase list $($for each new sale$)$

Note:

$$ Use arrays for the item data. That is$,$ you are not allowed to use other data types like

ArrayList, Vector, Set, etc.
