Programming paradigm/Object-oriented is a programming language feature.
Object-oriented programming (OOP) is a programming paradigm that uses "objects" to design applications and computer programs. It utilizes several techniques from previously established paradigms, including inheritance, modularity, interfaces, polymorphism, and encapsulation. Even though it originated in the 1960s, OOP was not commonly used in mainstream software application development until the 1990s. Today, many popular programming languages (such as Ada, Java, JavaScript, C#, VB.Net, C++, Python, PHP, Ruby and Objective-C) support OOP.


An object-oriented programming language (also called an OO language) is one that allows or encourages, to some degree, object-oriented programming techniques such as those listed above. Simula (1967) is generally accepted as the first language to have the primary features of an object-oriented language. It was created for making simulation programs, in which what came to be called objects were the most important information representation. Smalltalk (1972 to 1980) is arguably the canonical example, and the one with which much of the theory of object-oriented programming was developed.
