OOPS

Object Oriented Programming is a paradigm that provides many concepts such asinheritance, data binding, polymorphism etc. Object Oriented Programming is a methodology to design a program using classes and objects. The concepts of OOPS are :

  • Object : Any entity that has state and behavior is known as an object.
  • Class: Collection of objects is called class.
  • Inheritance : When one object acquires all the properties and behaviours of parent object it is known as inheritance.
  • Polymorphism : One task being performed in several ways is called as polymorphism.
  • Abstraction : Hiding internal details and showing functionality is known as abstraction.
  • Encapsulation : Binding code and data together into a single unit is known as encapsulation.

Object based programming language follows all the features of OOPs except Inheritance. JavaScript and VBScript are examples of object based programming languages.
