Visual Basic Invoice Class Application

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 instance variables?(private) a part number (type String), a part description (type String), a quantity of the item being purchased (type int ) -in case of negative value set this to zero price per item (double) -in case of negative value set this to zero Constructor Your class should have a constructor(with 3 parameter) that initializes the four instance variables. Methods Provide a set and a get method for each instance variable. In addition, provide a method named getInvoiceAmount that calculates the invoice amount (i.e., 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 0. If the price per item is not positive, it should be set to 0.0. Write a test application named InvoiceTest that demonstrates class Invoice?s capabilities. provide a method getInvoiceDetail that returns all the information(in the form of string) contained in the invoice object
