Inheritance is a means where a class borrows ("inherits") functionality from a base class, usually as a means of code reuse; the subclass will often add additional functionality or modify the behavior of the base class. Packages are simply a way of organizing code into namespaces, such that: Only classes that are actually part of the application logic are included, to prevent conflicts from classes that have the same name, and to logically organize code so that similar functionality can be grouped together.
