NOTE: The Array, ArrayList or List class may not be used Write a program that will create an invoice for a customer order based on their requests. Your program should prompt the user for their requested items based on a stock number then store the associated information in an array to be displayed in the invoice. 1. Define a Java class as described below. All variables should be declared as private and all methods as public. Save the class definition in a file with an appropriate filename. Class Name: Inventory Instance Variables: itemName - String price - double quantity - integer Instance Methods: A default constructor A constructor that accepts three arguments, one for each of the fields. getter methods for each of the class fields. toString() A method to display the fields of an instance of the class in to be displayed on the order sheet. Compile and debug the above code. 1. Then, create a class, TestInventory that contains a main() with static methods to create an invoice using the above class. Save the class in a file with an appropriate file name. • Declare four initialized arrays, one for the Stock Number, and three associated arrays for the Item Name, Price and Quantity. Initialize the Item Name array with your own String values:

Initialize the Item Name array with your own String values:
Stock Number Item Name Price Quantity 0372 1596 2117 4580 8529 $2.79 68 13.50 12 7.52 29 30.42 40 16.58 6 • Create a method that will prompt the user for the number of items the user wishes to order and create an order array that will store instances of the Inventory class. • Using the arrays, create a static method that will populate the above array with the items ordered by the user. This method should: -prompt user for the requested stock number and quantity of items to purchase; -using a loop, search the Stock Number and Quantity arrays for a valid order (Your program should handle invalid stock numbers and quantities entries and prompt the user for a new entry.) - update the Quantity array to reflect the decreased available amount extract the corresponding item name and price; -instantiate an instance of the Inventory object and insert it into the order array. • Call a static method to create an order invoice displaying the contents of the order array using the toString instance method. The invoice should also display the extended price of the items along with a final total The Array, List or ArrayList class may not be used
