Three Categories of Methods

Base methods - essential functionality not usually overridden. Example: drawing a circle.
Algorithm methods - the abstract algorithm that describes the problem being solved. Example: the event loop. Not usually overridden.
Abstract methods - the methods that do the actual work, usually overridden in each new application. Example - repaint the window.
