Object-Oriented Paradigm http://cs.mst.edu The Concept Bundled - PowerPoint PPT Presentation

Object-Oriented Paradigm http://cs.mst.edu

The Concept  Bundled together in one object  Data Types  Functionality  Encapsulation  State variables used to describe the object  Functions dictating how the object interacts and interfaces with other entities http://cs.mst.edu
