I am receiving an error and I am not sure how to fix this to get my code running. What would the code fixed look like? The errors are on lines 24-27 on the last picture. I have written this in java and the errors say

PartNumber cannot be resolved to a variable line 24

PartDescription cannot be resolves to a variable

Line 25

PartQuantity cannot be resolved to a variable

Line 26

PricePerItem cannot be resolved to a variable

Line 27

Copy of my 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 variablesa 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.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 app named InvoiceTest that demonstrates class Invoices capabilities.
