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).
This comparison of programming languages compares how object-oriented programming languages such as C++, Java, Smalltalk, Object Pascal, Perl, Python, and others manipulate data structures. Object construction and destruction
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 .
The concept of object is used in many different software contexts, including: Possibly the most common use is in-memory objects in a computer program written in an object-based language. Information systems can be modeled with objects representing their components and interfaces.
In object-oriented programming, the singleton pattern is a software design pattern that restricts the instantiation of a class to a singular instance. It is one of the well-known "Gang of Four" design patterns , which describe how to solve recurring problems in object-oriented software. [ 1 ]
Extends C with object-oriented programming and generic programming. C code can most properly be used. Strongly influenced by C++/C syntax. Compatible with C source code, except for a few corner cases. Provides the Java Native Interface and recently Java Native Access as a way to directly call C/C++ code.
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. [4]
Many object-oriented programming languages permit a class or object to replace the implementation of an aspect—typically a behavior—that it has inherited. This process is called overriding . Overriding introduces a complication: which version of the behavior does an instance of the inherited class use—the one that is part of its own class ...
