Object Oriented Programming

Introduction
Object oriented programming focuses on defining a hierarchy of classes of objects, each with associated data fields and methods. Subclasses inherit data fields and methods from their parent and ancestor classes.
Object oriented programming is generally considered good for software re-use and maintenance as objects, with clearly defined interfaces can be used and modified with relatively little effort. It has been widely used in creating user interface libraries and toolkits.
Object Oriented Programming
OOP is a programming language that is based on the Object Orientation methodology. The major advantages of OOP is its capabilities for creating flexible, modular programs and its abilities of code reuse.
Object orientation provides a new paradigm for software con-struction. In this new paradigm, objects and classes are the build¬ing blocks, while methods, messages and inheritance produce the primary mechanisms
Object-oriented programming is a programming method that combines data and instructions into a self-sufficient “object”. In an object-oriented program, the design is represented by objects. Objects
