Object-oriented programming (OOP) is a programming paradigm based on the concept of objects, [1] which can contain data and code: data in the form of fields (often known as attributes or properties), and code in the form of procedures (often known as methods).
Object-Oriented Software Construction, also called OOSC, is a book by Bertrand Meyer, widely considered a foundational text of object-oriented programming. [citation needed] The first edition was published in 1988; the second edition, extensively revised and expanded (more than 1300 pages), in 1997.
An object-based language is a programming language that provides a construct to encapsulate state and behavior as an object. A language that also supports inheritance or subtyping is classified as object-oriented. [1]
Such object models are usually defined using concepts such as class, generic function, message, inheritance, polymorphism, and encapsulation. There is an extensive literature on formalized object models as a subset of the formal semantics of programming languages .
Object-oriented analysis and design (OOAD) is a technical approach for analyzing and designing an application, system, or business by applying object-oriented programming, as well as using visual modeling throughout the software development process to guide stakeholder communication and product quality.

The listed languages are designed with varying degrees of OOP support. Some are highly focused in OOP while others support multiple paradigms including OOP. [ 1 ] For example, C++ is a multi- paradigm language including OOP; [ 2 ] however, it is less object-oriented than other languages such as Python [ 3 ] and Ruby .
