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 variable   Part number(type String)   Part description(type String)   Quantity of the item being purchased (type int)   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 getInvoice Amount 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

Question

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 variable

  1.  

Part number(type String)

  1.  

Part description(type String)

  1.  

Quantity of the item being purchased (type int)

  1.  

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

getInvoice Amount 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.

3. 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 variable a. Part number(type String) b. Part description(type String) c. Quantity of the item being purchased (type int) d. 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 getlnvoice Amount 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 Invoice Test that demonstrates class Invoice's capabilities.
