why we need object oriented programming language?

Object-oriented programming aims to implement real-world entities like inheritance, hiding, polymorphism etc in programming. The main aim of OOP is to bind together the data and the functions that operate on them so that no other part of the code can access this data except that function. OOPs Concepts: Polymorphism.

Security – While most languages have some security, object-oriented languages are convenient because security is built-in with encapsulation. Other methods and classes cannot access private data by default, and programs written in OOP languages are more secure for it.

Python has been an object-oriented language since it existed. Because of this, creating and using classes and objects are downright easy. Compared with other programming languages, Python's class mechanism adds classes with a minimum of new syntax and semantics.

UML is not a programming language but there are tools that can be used to generate code in various languages using UML diagrams. UML has a direct relation with object-oriented analysis and design.

Some of the disadvantages of object-oriented programming include: 1. Steep learning curve: The thought process involved in object-oriented programming may not be natural for some people, and it can take time to get used to it. It is complex to create programs based on interaction of objects.

Object-oriented methodology relies on three characteristics that define object-oriented languages: encapsulation, polymorphism, and inheritance.

Object-oriented programming System(OOPs) is a programming paradigm based on the concept of “objects” that contain data and methods. ... Object oriented programming brings together data and its behaviour(methods) in a single location(object) makes it easier to understand how a program works.

An object-oriented programming is a way programming which enables programmers to think like they are working with real-life entities(a thing with distinct and independent existence) or objects. ... In OOP, objects have fields to store knowledge/state/data and can do various works — methods.

Object oriented programming provides data hiding so it is more secure. In procedural programming, overloading is not possible. Overloading is possible in object oriented programming. In procedural programming, function is more important than data.

Significant object-oriented languages include Java, C++, C#, Python, R, PHP, JavaScript, Ruby, Perl, Object Pascal, Objective-C, Dart, Swift, Scala, Kotlin, Common Lisp, MATLAB, and Smalltalk.

Explanation: Object oriented programming follows a conceptual framework called object model and is implemented by writing classes and objects to make its style clear unlike procedure- oriented language.

Object Oriented programming is a programming style which is associated with the concepts like class, object, Inheritance, Encapsulation, Abstraction, Polymorphism. ... follow an object-oriented programming paradigm.

Python has rich library, it is also object oriented, easy to program. It can be also used as frontend language. That's why it is used in artificial intelligence. Rather than AI it is also used in machine learning, soft computing, NLP programming and also used as web scripting or in Ethical hacking.

The objects are processed by their member data and functions. It is easy to analyze the user requirements. With the help of inheritance, we can reuse the existing class to derive a new class such that the redundant code is eliminated and the use of existing class is extended. This saves time and cost of program.

Structured programming languages focuse on the process and then data. This is because in these types of languages we first call a function and then the instruction uses data to execute. In object-oriented programming, data and information are important.

Object-Oriented Programming (PHP OOP), is a type of programming language principle added to php5, that helps in building complex, reusable web applications. The Object Oriented concepts in PHP are: ... You define a class once and then make many objects that belong to it. Objects are also known as instance.

Traditional approaches like waterfall, spiral lack flexibility to deal with object oriented models. ... Object oriented development approaches are best suited to projects that will imply systems using emerging object technologies to construct, manage, and assemble those objects into useful computer applications.
