Object-oriented programming

Object-oriented programming (OOP) is a programming paradigm based on the concept of "objects", which may contain data, in the form of fields, often known as attributes; and code, in the form of procedures, often known as methods. A feature of objects is that an object's procedures can access and often modify the data fields of the object with which they are associated (objects have a notion of "this" or "self").

A method in object-oriented programming (OOP) is a procedure associated with a message and an object.

There is significant diversity of OOP languages, but the most popular ones are class-based, meaning that objects are instances of classes, which typically also determine their type. Languages that support object-oriented programming typically use inheritance for code reuse and extensibility in the form of either classes or prototypes.

Class-based programming, or more commonly class-orientation, is a style of Object-oriented programming (OOP) in which inheritance occurs via defining classes of objects, instead of inheritance occurring via the objects alone (compare prototype-based programming).

Java,

Java is a general-purpose computer-programming language that is concurrent, class-based, object-oriented, and specifically designed to have as few implementation dependencies as possible.

C++, C#,

It has imperative, object-oriented and generic programming features, while also providing facilities for low-level memory manipulation.

In object-oriented programming (OOP), an instance is a concrete occurrence of any object, existing usually during the runtime of a computer program.

Python,

It supports multiple programming paradigms, including object-oriented, imperative, functional and procedural, and has a large and comprehensive standard library.

Object Pascal,

Object Pascal refers to a branch of object-oriented derivatives of Pascal, mostly known as the primary programming language of Delphi.

C++, C#,

C# (pronounced C sharp) is a general-purpose, multi-paradigm programming language encompassing strong typing, imperative, declarative, functional, generic, object-oriented (class-based), and component-oriented programming disciplines.

Objective-C,

Objective-C is a general-purpose, object-oriented programming language that adds Smalltalk-style messaging to the C programming language.

Smalltalk.

Smalltalk is an object-oriented, dynamically typed reflective programming language.

JavaScript,

As a multi-paradigm language, JavaScript supports event-driven, functional, and imperative (including object-oriented and prototype-based) programming styles.

Scala,

Like Java, Scala is object-oriented, and uses a curly-brace syntax reminiscent of the C programming language.

Dart,

Dart is an object-oriented, class defined, garbage-collected language using a C-style syntax that transcompiles optionally into JavaScript.

Object-oriented programming (OOP) is a programming paradigm based on the concept of "objects", which may contain data, in the form of fields, often known as attributes; and code, in the form of procedures, often known as methods. A feature of objects is that an object's procedures can access and often modify the data fields of the object with which they are associated (objects have a notion of "this" or "self").

In the class-based object-oriented programming paradigm, object refers to a particular instance of a class, where the object can be a combination of variables, functions, and data structures.

Common Lisp,

It supports a combination of procedural, functional, and object-oriented programming paradigms.

Many of the most widely used programming languages (such as C++, Object Pascal, Java, Python etc.) are multi-paradigm programming languages that support object-oriented programming to a greater or lesser degree, typically in combination with imperative, procedural programming.

The concepts behind object-oriented programming attempt to extend this approach.

PHP,

On July 14, 2004, PHP 5 was released, powered by the new Zend Engine II. PHP 5 included new features such as improved support for object-oriented programming, the PHP Data Objects (PDO) extension (which defines a lightweight and consistent interface for accessing databases), and numerous performance enhancements.

Languages that support object-oriented programming typically use inheritance for code reuse and extensibility in the form of either classes or prototypes.

In object-oriented programming, inheritance is the mechanism of basing an object or class upon another object (prototype-based inheritance) or class (class-based inheritance), retaining similar implementation.

Prototype-based programming is a style of object-oriented programming in which behaviour reuse (known as inheritance) is performed via a process of reusing existing objects

Objects are created by calling a special type of method in the class known as a constructor.

In class-based object-oriented programming, a constructor (abbreviation: ctor) is a special type of subroutine called to create an object.

In some languages classes and objects can be composed using other concepts like traits and mixins.

In computer programming, a trait is a concept used in object-oriented programming, which represents a set of methods that can be used to extend the functionality of a class.

Variables that can store information formatted in a small number of built-in data types like integers and alphanumeric characters. This may include data structures like strings, lists, and hash tables that are either built-in or result from combining variables using memory pointers

In object-oriented programming, pointers to functions are used for binding methods, often using what are called virtual method tables.

Procedures – also known as functions, methods, routines, or subroutines – that take input, generate output, and manipulate data. Modern languages include structured programming constructs like loops and conditionals.

The discipline of object-oriented programming is based on objects and methods (which are subroutines attached to these objects or object classes).

A feature of objects is that an object's procedures can access and often modify the data fields of the object with which they are associated (objects have a notion of "this" or "self").

In object-oriented programming, field (also called data member or member variable) is the data encapsulated within a class or object.
