"Our company manages deliveries, such as letters and packages. Letters contain just text. Packages contain one or multiple items. The items could be anything that can be shipped. It must be represented as an interface in the application with a single method that returns the description of the item. These deliveries are transported via cargo ships, cargo airplanes, and mail trucks. Each transport vehicle must have a load method that puts a mail item onto it."

1. Design the interfaces and classes above using inheritance, abstract classes, and classes with inheritance.
