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 constructor that requires arguments for weight and shipping method. The constructor calls a calculateCost() method that determines the shipping cost, based on the following table:
| Weight (oz.) | Air ($) | Truck ($) | Mail ($) |
| 1 to 8 | 2.00 | 1.50 | .50 |
| 9 to 16 | 3.00 | 2.35 | 1.50 |
| 17 and over | 4.50 | 3.25 | 2.15 |
The Package class also contains a display() method that displays the values in all four fields. Create a subclass named InsuredPackage that adds an insurance cost to the shipping cost, based on the following table:
| Shipping Cost Before Insurance ($) | Additional Cost ($) |
| 0 to 1.00 | 2.45 |
| 1.01 to 3.00 | 3.95 |
| 3.01 and over | 5.55 |
Write an application named UsePackage that instantiates at least 3 objects of each type (Package and InsuredPackage) using a variety of weights and shipping method codes. Display the results for each Package and InsuredPackage. Save the files as Package.java, InsuredPackage.java, and UsePackage.java.
