Creating Invoice of a Shop in Java

Problem:

Assume you own a grocery shop where clients always buy 3 items (all prices are in

dollars). To facilitate the billing process you write a program that reads the item
names and prices and generates an invoice. For example, if a client buys Chocolate
(at $0.5), Gum (at $1), Water (at $0.5), the program output should look as follow:
Please enter the first item name:
Chocolate
Please enter the first item price:
1.5
Please enter the second item name:
Gum
Please enter the second item price:
1.5
Please enter the third item name:
Water
Please enter the third item price:
1.5
Invoice is:
Chocolate $1.5
Gum $1.5
Water $1.5
Total $4.5
Note that all prices are in dollars and you should use number formats to generate the invoice (do not use string concatenation to add the dollar sign).
