Hey Everyone,
I'm new to this form, and I seem to like it so far. Anyways, I have this Project that i'm nearly done with but in the sub-class I'm getting 0.0 as an output instead of the actual calculation. Below is the project and the code:
You are requested to design the class Package with instance variables representing package number, weight, and shipping method. The shipping method is a character: A for Air, T for Truck, and M for Mail. The class contains a constructor that requires arguments for weight and shipping method. The constructor should create automatic unique package numbers. The class defines a calculateCost()method that determines the shipping cost of a package based on the following:
Weight (in kg) Shipping method
-----------------------Air---Truck---Mail
1 - to - 8 ------------2.00---1.50---0.5
9 - to - 16 -----------3.00---2.35---1.50
17-to-over ------------4.50---3.25---2.15
The package class also contains a method display()that displays the values of a package object.
Create a subclass InsuredPackage that adds an insurance cost to the shipping cost based on the following:
Shipping cost before insurance (in $)-----Additional cost
10.00 to 100.00 --------------------------15.00
10.001 to 300.00--------------------------25.50
301.00 to over --------------------------34.00
Create a class Owner that represents the owner of a package. The class should contain an array reference that references the packages belonging to the owner, in addition to the name, mailing address, and owner ID (created automatically and uniquely by the constructor).
Write a test program that interacts with the user to create a number of owners and packages belonging to them. The program must allow the user to request a report showing information about owners and their packages.
