The object-oriented paradigm is compelling because it gives us a concrete way to think about and represent the core functionality of our programs. By organizing our programs around objects and data rather than actions and logic, we have a robust and flexible way to build complex applications. The actions and logic are still present, of course, but by embodying them in objects, we have a way to encapsulate functionality, allowing objects to change in very specific ...
