OOPS – Object Oriented Programming,  is a concept of designing your programming model in to Classes and Object.

OOPS Concept aims to incorporate the advantages of modularity and re-usability. Objects, which are usually instances of classes, are used to interact with one another to design applications and computer programs.

The important features of object–oriented programming are:

  • Bottom–up approach in program design
  • Programs organised around objects, grouped in classes
  • Focus on data with methods to operate upon object’s data
  • Interaction between objects through functions
  • Re-usability of design through creation of new classes by adding features to existing classes.

Base of OOPS:

Fundamental concepts which makes programming model as Object Oreiented are:

  • Encapsulation,
  • Inheritance,
  • Polymorphism, and
  • Abstraction.
