What is polymorphism object-oriented programming?

What is polymorphism object-oriented programming?

Polymorphism is a feature of object-oriented programming languages that allows a specific routine to use variables of different types at different times. Polymorphism is the ability of a programming language to present the same interface for several different underlying data types.

What are object-oriented programming concepts?

Now, there are four fundamental concepts of Object-oriented programming – Inheritance, Encapsulation, Polymorphism, and Data abstraction. It is very important to know about all of these in order to understand OOPs.

What is polymorphism in object-oriented programming with examples?

Polymorphism is one of the OOPs feature that allows us to perform a single action in different ways. For example, lets say we have a class Animal that has a method sound() . Since this is a generic class so we can’t give it a implementation like: Roar, Meow, Oink etc. We had to give a generic message.

What is polymorphism explain with examples?

The word polymorphism means having many forms. In simple words, we can define polymorphism as the ability of a message to be displayed in more than one form. Real life example of polymorphism: A person at the same time can have different characteristic. Like a man at the same time is a father, a husband, an employee.

What is the difference between object oriented programming language and object based programming language?

Object-oriented languages do not have the inbuilt objects whereas Object-based languages have the inbuilt objects, for example, JavaScript has window object. Examples for Object Oriented Languages include Java, C# whereas Object-based languages include VB etc.

What is the first object oriented programming language?

Simula (1967) is generally accepted as being the first language with the primary features of an object-oriented language. Smalltalk (1972 to 1980) is another early example, and the one with which much of the theory of OOP was developed.

How is inheritance used in object oriented programming?

Inheritance is the process by which new classes are created from existing classes and inherit the general characteristic of those classes. Consider the person class that is used to create two new classes called woman and man. The new classes inherit the properties of the person class, which saves a lot of coding.

When did object oriented programming become a language?

Since the 1980s the word ‘object’ has appeared in relation to programming languages, with almost all languages developed since 1990 having object-oriented features. Some languages have even had object-oriented features retro-fitted.

What are the features of object oriented programming?

An object-oriented programming language generally supports five main features: If we think of a real-world object, such as a television (as in Figure 1.1), it will have several features and properties: We do not have to open the case to use it. We have some controls to use it (buttons on the box, or a remote control).

How is encapsulation used in object oriented programming?

The object-oriented paradigm encourages encapsulation. Encapsulation is used to hide the mechanics of the object, allowing the actual implementation of the object to be hidden, so that we don’t need to understand how the object works. All we need to understand is the interface that is provided for us.
