Question
Create a class named Order that processes the order of a single item. The class has five (5) fields:
Customer name, customer number, quantity ordered, unit price and total price. Write set and get methods for each field, except for the total price field. The set methods must prompt the user to enter the values for the following fields: customer name, customer number, quantity ordered and unit price. This class also needs a calculatePrice() method to calculate the total price (quantity multiplied by unit price) and a method to display the field values.
Add a subclass named SpeedOrder for customers that require delivery of the ordered item within 24 hours. To deliver an ordered item within 24 hours after processing the order, the customer will be charged an extra R120.00. Override the calculatePrice() method by adding the speed courier fee of R120.00 to the calculated price.
Create the logic to test the two (2) classes in an application that instantiates an object of each of these two (2) classes. Prompt the user for data for the first object and display the results; then prompt the user for data for the SpeedOrder object and display the results.
