Java Polymorphism
Polymorphism is an important concept of object-oriented programming. It simply means more than one form.
That is, the same entity (method or operator or object) can perform different operations in different scenarios.
Example: Java Polymorphism
Output
In the above example, we have created a superclass: and two subclasses: and . Notice the use of the method.
The main purpose of the method is to render the shape. However, the process of rendering a square is different than the process of rendering a circle.
Hence, the method behaves differently in different classes. Or, we can say is polymorphic.
Why Polymorphism?
Polymorphism allows us to create consistent code. In the previous example, we can also create different methods: and to render and , respectively.
This will work perfectly. However, for every shape, we need to create different methods. It will make our code inconsistent.
To solve this, polymorphism in Java allows us to create a single method that will behave differently for different shapes.
Note: The method is also an example of polymorphism. It is used to print values of different types like , , , etc.
We can achieve polymorphism i
What is Polymorphism: An Introduction with Examples in Java and Python
Sharing is caring
In this post, we will introduce the object-oriented programming concept of polymorphism using examples in Java and Python.
What is Polymorphism?
Polymorphism is the ability of an object to assume multiple forms. For example, a motorbike is some type of bike. It is also some type of motorized vehicle. The motorbike is polymorphic because it appears in the form of a motorized vehicle and in the form of a bike. In object-oriented programming, polymorphism is closely tied to the notion of an interface. You can check if an object is polymorphic by asking whether the object is also an object of another type. In Java, all objects are polymorphic because in addition to being objects of their own class they are also general Java objects.
What is an Interface?
An interface defines a set of behaviors that an object needs to have. For example, you could create a Bike interface that defines that an object conforming to Bike needs to have an attribute called “number of wheels”, an “accelerate” method, and a “stop” method.

Polymorphism in Java with realtime Example
Polymorphism is another fundamental principal of object-oriented programming. Sometimes beginners find it little difficult to understand what exactly the polymorphism is, so we will try to see this with some real world examples and programs to understand this easily. This tutorial covers different aspect of polymorphism like what is polymorphism, real world example, advantages of polymorphism etc.
What is Polymorphism in Java
The word polymorphism is made from two words, which means and which means , so the word polymorphism means many forms. Polymorphims in java is a mechanism in which an object or it's behavior can have many different forms, we call such objects as polymorphic object.
Programmatically, in java the object of a child class can be assigned in any of its parent classes in the inheritance hierarchy which means the object of a subclass can take the form of any of it's parent classes in it's inheritance hierarchy, so we can say all the parent classes are basically different forms of child class, which is what the polymorphism is.
For example let's consider a scenario in which we have class A, B and C where class C ex
Polymorphism in Java with Examples
Polymorphism is a key concept of Object-Oriented Programming (OOP) that allows Java to use one class for multiple purposes. The word “Polymorphism” means many forms. It reflects how Java classes can provide different behaviours for a method.
According to Glassdoor, the average salary of a Java Developer in the UK is about £55, annually. It is a great job with lots of perks and benefits. If you want to become a Java Developer, then you should be familiar with important concepts like Polymorphism in Java.
