Question

(JAVA)

1) Write a blueprint class that tracks the orders made to vendors in a company's product purchasing system. We will create a class called ProductOrder. The requirements are as follows: a) The class ProductOrder has the following private instance variables:productID orderld, quantityRequested quantity Fulfilled all of types integer. We will need separate variables for quantity requested and quantity fulfilled because the vendors may not be able to fulfill the requests completely b) The class/object model will provide the values of the quantityRequested and quantityFulfilled to the client program. To do this, have proper getters and setters for the instance variables. c) The class/object model has method, calculate Payment that will calculate the pending payments to be made to vendors for the product quantity fulfilled. To do this, the method will receive the payment price as a parameter and multiply this price with the quantity Fulfilled to determine the payments that are due. Write a method in the class that will take in a (double) parameter called price and returns the value of the payment due (also a double). This value of payments due is the amount that the company will need to pay to the vendor.

    }

    public void printPendingOrder(){
