Exercise 2: Your friend who works at the superstore is urgently in need of your help with some basic sales records. Consider a class Sales that keeps track of the sales of one item in the store. An object of this class will have the attributes
Name of the item
Cost of the item
Bulk quantity (to qualify for discount)
Discount (percentage)
Number sold
Total amount
Total discount
and the following methods
Constructor that sets the cost, bulk quantity and the discount
Get and set methods for cost, bulk quantity and discount
registerSale(int n) records the sale of n items. If n is larger than the bulk quantity, the cost will be reduced by the discount.
displaySales displays the name of the item, number sold, the total amount, and total discount.
Ignore sales tax.
Implement the class and test it. For example, for
Item: Shampoo
Cost: 2.50
Bulk quantity (to qualify for discount): 4
Discount: 10 percent
Number sold: 10
The output would be:
Shampoo
Number sold: 10
Total amount: $ 22.50
Total discount: $ 2.50
As another example, for
Item: Toothpaste
Cost: 1.99
Bulk quantity: 20
Discount: 15
Number sold: 10
The output would be:
Toothpaste
Number sold: 10
Total amount: 19.90
Total discount: 0

}
else

totDiscount=0;
}
}
public void displaySale()
{
// DecimalFormat class is used to format the output
DecimalFormat df = new DecimalFormat("0.00");
System.out.println(" "+itemName);
System.out.println("Number sold: "+sold);
System.out.println("Total amount: $ "+df.format(totAmount));
System.out.println("Total discount: $ "+df.format(totDiscount));
}
