3.12 (Invoice Class) Create a class called Invoice that a hardware store might use to represent an invoice for an item sold at the store. An Invoice should include four pieces of information as a Chapter 3 Introduction to Classes, Objects, Methods and Strings instance variables-a part number (type String), a part description (type String), a quantity of the item being purchased (type int) and a price per item (double). Your class should have a constructor that initializes the four instance variables. Provide a set and a get method for each instance variable. In addition, provide a method named getInvoiceAmount that calculates the invoice amount (i.c. multiplies the quantity by the price per item), then returns the amount as a double value. If the quantity is not positive, it should be set to o. If the price per item is not positive, it should be set to 0.0. Write a test app named InvoiceTest that demonstrates class Invoice's capabilities
