Object Oriented Programming - Research Paper Example

A Computer Program is a series of instructions that tells a computer what tasks it needs to perform and in what sequence. These programs are often written in high-level languages that are further converted into machine language to make the instructions understandable for computers. A program or a comprehensive set of instructions that are designed to achieve a particular objective is referred to as a function or a method. These functions always work on related data.

Two paradigms are object-oriented followed to write computer programs: ‘procedural’ or ‘A procedural.’Paradigm comprises creating a sComparedet of functions or modules and is sometimes referred to as a modular object-oriented compared to this, in an antogetherobjectt oriented approach, related data and functions are grouped to create objects. Data items are termed as attributes and functions are termed as behaviors in an object-orienorientedte paradigm. Their encapsulation through a mechanism furnishes a blueprint for an object which is referred to as a ‘class’.

It is like a script of a movie or a recipe for a dish. CORE CONCEPTAn object Oriented approach towards the creation of a program is based upon the identification of objects at first. The three main principles that lie at the core of Object Oriented Programming are encapsulation, inheritance, and polymorphism. An object is a separate instance of a class. It is a combination of data and methods. A class may contain multiple objects. Objects may be composed of smaller objects and the features of basic objects can be inherited into the specialized objects of the same tree.

These objects can be used or invoked only through their allowed interfaces which are methods. They may interact with each other using these interfaces. Inheritance is the phenomenon whereby which an object inherits the basic properties of the class to which it belongs. The objects are capable of exhibiting multiple functioning within a single interface. This property is known as polymorphism.
