Question

Using Java,

Class Invoice could be used by a hardware store to represent an invoice for an item sold at the store. An Invoice should include four pieces of information as instance variables—a part number, a part description, a quantity of the item being purchased, and a price per item. Code the class with the instance variables and a constructor for the class that initializes the four instance variables with values received by parameters of the same name.
