Q1) Create a class named Purchase that performs order processing of a single item. The class has five fields: customer name, customer number, quantity ordered, unit price, and total price. Include set and get methods for each field except the total price field. The set methods prompt the user for values for each field. This class also needs a method to compute the total price (quantity times unit price) and a method to display the field values. Create a subclass named PurchaseOrder that overrides purchasePrice() by adding a shipping and handling charge of $5.00. Write an application named UseOrder that instantiates an object of each of these classes. Prompt the user for data for the Order object, and display the results; then prompt the user for data for the PurchaseOrder object, and display the results .
