Object-Oriented
Programming
type of programming in which programmers define not only the data structures, but also the types of operations (methods) that can be applied to the data structure enables programmers to create modules that do not need to be changed when a new type of object is added most widely used paradigm instead of focusing on what the system has to do, focus on:


what objects the system contains



how they interact towards solving the programming problem
