Interview Question : What is Object Oriented Programming?

Object Oriented Programming Languages - Winged Post

Object Oriented Programming (OOP) is a type of programming in which programmers define not only the data type of a data structure, but also the types of operations (functions) that can be applied to the data structure. In this way, the data structure becomes an object that includes both data and functions. In addition, programmers can create relationships between one object and another. For example, objects can inherit characteristics from other objects.

The Object Oriented Programming can also be defined as:

1. A style of programming that focuses on using objects to design and build applications.

2. Object oriented programming (OOP) is a model of programming language that focuses on the use of objects instead of actions in order to carry out tasks. This involves taking an approach that is more mindful of data and less concerned with logic, which is more commonly the case in other programming paradigms.

3. Object-oriented programming (OOP) is a programming paradigm based on the concept of “objects”, which are data structures that contain data, in the form of fields, often known as attributes; and code, in the form of procedures, often known as methods.


For your information, the following are some additional concepts associated with the Object Oriented Programming:

  1. Encapsulation means that a group of related properties, methods, and other members are treated as a single unit or object.
  2. Inheritance describes the ability to create new classes based on an existing class.
  3. Polymorphism means that you can have multiple classes that can be used interchangeably, even though each class implements the same properties or methods in different ways.
