1) Create a Java Project.

2) Create a class named Package.java 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.

3) The Package class contains a constructor that requires arguments for weight and shipping method.

- The Package class also contains a Display() method. It displays values in 3 fields (weight, ship method and cost) rather than 4.

- The constructor calls a calculateCost() method that determines the shipping cost, based on the following table:

4) Create a subclass named InsuredPackage that adds an insurance cost to the shipping cost, based on the following table:

5) 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.

- Use the shipping types with the weights seen in the output below.

Output:

Packages:

The package weighs 4 ounces. Ship method A Cost $2.00

The package weighs 10 ounces. Ship method T Cost $2.35

The package weighs 20 ounces. Ship method M Cost $2.15

Insured packages:

The package weighs 4 ounces. Ship method A Cost $5.95

The package weighs 10 ounces. Ship method T Cost $6.30

The package weighs 20 ounces. Ship method M Cost $6.10
