Create a class named Package with data fields for weight in ounces, shipping method, and shipping cost. The shipping method is a character: A for air, T for truck, or M for mail. The Package class contains a constuctor that requires arguments for weight and shipping method. The constructor calls a calculateCost() method that determines the shipping cost, based on the table shown on page 531.
The Package class also contains a display() method that displays the values in all four fields. Create a subclass named InsuredPackage that adds an insurance cost to the shipping cost, based on the table on page 532.
Write an application named UsePackage that instantiates at least three objects of each type (Package and InsuredPackage) using a variety of weights and shipping method codes. Display the results for each Package and InsuredPackage.
