Programming Design Order

Complete the following tasks:

  • Create a class named Order that performs order processing of a single item. The class has four fields: customer name, customer number, quantity ordered, and unit price. Include set and get methods for each field. The set methods prompt the user for values for each field. Tis class also needs a computePrice() method to compute the total price (quantity multiplied by unit price) and a method to display the field values.
  • Create a subclass named ShippedOrder that overrides computePrice() by adding a shipping and handling charge of $4.00.
  • Create the logic for an application that instantiates an object of each of these two classes. Prompt the user for data for the Order object and display the results; then prompt the user for data for the ShippedOrder object and display the results.
