Object-oriented Operating Systems
Object-oriented programming (OOP) is a programming paradigm based on the concept of ''Object (computer science), objects''. Objects can contain data (called Field (computer science), fields, Attribute (computing), attributes or Property (programming), properties) and have actions they can perform (called Procedure (computer science), procedures or method (computing), methods and implemented in source-code, code). In OOP, computer programs are designed by making them out of objects that interact with one another. Many of the most widely used programming languages (such as C++, Java (programming language), Java, and Python (programming language), Python) support object-oriented programming to a greater or lesser degree, typically as part of multi-paradigm, multiple paradigms in combination with others such as imperative programming and declarative programming. Significant object-oriented languages include Ada (programming language), Ada, ActionScript, C++, Common Lisp, C Sharp (p ...
