Create a class named Package with data fields for wright 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 9 to 16 17 and over	2.00 3.00 4.50	1.50 2.35 3.25	.50 1.50 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 1.01 to 3.00 3.01 and over	2.45 3.95 5.55

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. Save the files as Package.java, InsuredPackage.java, and UsePackage.java.
