Question

The Luxury Ocean Cruise Outings company has provided Global Rain with a software specification document that details a menu-driven software application. Other developers on your software development team have already begun this project by creating the Ship, Cruise, Passenger, and Driver classes. You will modify the classes by including attributes and their proper data structures, writing methods to perform required functionality and behavior, and making sure that your program performs input validation and exception handling.
