What is the language of object-oriented programming

What are all the object-oriented programming languages?

Object-oriented programming languages are Smalltalk, Eiffel, C++, Java, PHP and so on.

1, Smalltalk is not a mere programming language, but a programming environment that reflects the ideas of object-oriented programming. This system emphasizes the oneness of object concepts, introduces concepts and terminology such as classes, methods, instances, applies single inheritance and dynamic binding, and becomes a notable milestone in the development of Object-Oriented Programming Languages (OOPL).

2, Eiffel’s main features are comprehensive static typing, a large number of development tools, support for multiple inheritance. eiffel also fully supports the concept of object-oriented.

3, C++ language is an object-oriented strongly typed language, introduced by AT&T’s Bell Labs in 1980. c++ language is an upwardly compatible expansion of the c language, rather than a new language. c++ is a multi-paradigm support for programming language, which supports both object-oriented programming and process-oriented programming. C++ supports the basic object-oriented concepts: objects, classes, methods, messages, subclasses, and inheritance.

What are the object-oriented programming languages?

What are the object-oriented programming languages? The relevant content is as follows:


Java is a widely used object-oriented programming language developed by SunMicrosystems (now OracleCorporation). It is designed to be platform-independent and to run on different operating systems.Key features of Java include strong typing, garbage collection, multi-threading support, and a rich standard library.


C++ is an extension of C that introduces the concepts of classes and objects and is a multi-paradigm programming language.C++ is very flexible as it supports object-oriented, procedural, and generic programming. It is widely used in systems programming, game development and embedded systems.


C# is an object-oriented programming language developed by Microsoft and commonly used for Windows applications and game development. It combines the performance of C++ with the portability of Java and provides a rich set of frameworks and tools.


Python is a high-level, interpreted, multi-paradigm programming language with support for object-oriented programming.Python’s clean syntax and large number of third-party libraries have made it one of the languages of choice in the fields of data science, machine learning, and web development.


Ruby is a dynamic, object-oriented programming language that emphasizes simplicity and flexibility. It has a strong standard library and an active community, and is widely used for web development, especially the RubyonRails framework.


Swift is an object-oriented programming language developed by Apple for iOS and macOS application development. It is designed to be easy to learn and use, while providing high performance and security.


Kotlin is a statically-typed language based on the Java Virtual Machine, which is widely used in Android app development.Kotlin improves the developer experience by simplifying code and providing modern language features.


PHP is a scripting language for web development that also supports object-oriented programming. It is widely used to build dynamic websites and web applications.


JavaScript is a scripting language for front-end web development that also supports object-oriented programming. JavaScript has become more object-oriented through the class and module system introduced by the ES6 standard.


Scala is a language that mixes functional and object-oriented programming and runs on the Java Virtual Machine.Scala emphasizes expressiveness and security of code and is widely used for large-scale, high-performance application development.

What are the main object-oriented languages

1, java.

Java is a widely used computer programming language, with cross-platform, object-oriented, generic programming features, widely used in enterprise-level Web application development and mobile application development.

The style of the Java programming language is very close to the C++ language. Inherited the core of the object-oriented technology of C++ language, discarded the pointers that can easily cause errors, replaced by references; removed the operator overloading and multiple inheritance characteristics of C++, replaced by interfaces; increase the garbage collector function.

2. c++.

C++ is a widely used computer programming language. It is a general-purpose programming language that supports multiple programming modes such as procedural programming, data abstraction, object-oriented programming, generic programming and design patterns.

3. c#.

C# is a Microsoft launched based on the .NET Framework, object-oriented high-level programming language. c# to the .NET Framework class library as the basis, with a similar VisualBasic rapid development capabilities.

C# was developed under the auspices of Anders Heilsberg, and Microsoft released the language in 2000 in hopes of using it to replace Java.C# has become a standard specification of Ecma International and the International Standards Organization.

4. python.

Python is an object-oriented, dynamically typed language that is interpreted, high-level programming, general-purpose programming language, created by Guido van Rossum, the first version was released in 1991.

What is an object oriented programming language ah?

Object-oriented language is a language that supports object-oriented programming, such as: c++, java, objectpascal

. All operations are based on objects, developed from procedural oriented languages, but it is this feature that makes object-oriented languages not very convenient for the underlying operations.

Objects in the real world have attributes and behaviors, which map to computer programs; attributes represent the data of an object, and behaviors represent the methods of an object (whose role is to process data or interact with the outside world).

Object-oriented programming languages support three concepts: encapsulation, polymorphism, and inheritance.

Encapsulation is the use of an autonomous framework to link the data and methods of an object together to form a whole. It can be said that the object is the means to support encapsulation and is the basic unit of encapsulation.

Polymorphism is a variety of forms of expression, specifically, can be expressed as “an external interface, more than one internal implementation of the method”.

Inheritance is the direct use of an object’s properties and methods by another object.

Object-oriented programming has the following advantages:

1, easy to maintain

Object-oriented thinking using the design of the structure, readability, due to the existence of inheritance, even if the change in demand, then the maintenance is only in the local module, so the maintenance is very convenient and low-cost.

2, easy to extend

Through inheritance, you can dramatically reduce redundant code, and extend the use of existing code;

You can build a program on a standard module (here the so-called “standard” means that programmers have reached an agreement with each other), without having to start everything from scratch. This can reduce software development time and improve productivity;

3, modularity

Encapsulation can define the access level of the object’s attributes and methods, through different access modifiers to the external exposure of the safe interface, to prevent the internal data in the case of insecure modification. This allows the program to have a higher degree of modularity and facilitates later maintenance and modification.

At the same time, object-oriented languages allow multiple instances of an object to exist at the same time, and they do not interfere with each other;

4, easy to model

While the object-oriented language objects and real-life objects is not the same concept, but very often, you can often use the concept of real-life objects after the abstraction of a slight modification of modeling, which greatly facilitates the modeling process. greatly facilitates the modeling process. (However, using real-life objects directly for modeling is sometimes counterproductive).

There are two directions in the development of object-oriented languages:

One is a pure object-oriented language, such as Smalltalk, EIFFEL, etc.

The other is a hybrid object-oriented language, that is, procedural languages and other languages to add classes, inheritance and other components, such as C++, Objective-C and so on.

It is generally accepted that the more typical object-oriented languages are:

SIMULA67, which supports single inheritance and polymorphism of some meaning and partial dynamic binding;

Smalltalk, which supports single inheritance, polymorphism and dynamic binding;

EIFFEL, which supports multiple inheritance, polymorphism and dynamic binding;

C++. Supports multiple inheritance, polymorphism and partial dynamic binding.
