Let’s understand inheritance with the help of a real-world example: In Inheritance, as the name suggests, one class inherits the properties of another class. Now let’s connect both the classes using Inheritance. Methods will be placed in different classes.
So, the answer is that they differ in location. Now you must be wondering how these methods are different from each other if their name and signatures are the same. In method overriding, we will have many methods, and this time the number of arguments will also be the same. Instead, we manipulate the arguments using the same method repeatedly. Here, we don’t mention the function definition multiple times. However, you can implement method overloading in the above way in Java, C++, etc.Īn alternative to performing method overloading in Python would be in this way: class OverloadingExample: We can still overload methods in python but it would be of no use. Note: Python does not support method overloading, this is because python always picks up the latest defined method. Now that you know what polymorphism is, the concept of method overloading is easy to understand.Īs the name suggests, we are overloading the methods, which means there would be many methods with the same name within a class, but having a different number of arguments. The max() is an example where the method has the same name but different implementations.
But the number and types of arguments are different every time. We use the same method every time, i.e., max(), which performs the same function every time, i.e., to find the maximum value. In programming terms, it means that there can be many functions with the same name but different forms, arguments, or operations.Īn Example of Polymorphism in Python: print(max(10,20)) Morphism means forms. So, polymorphism means “many forms”. To understand method overloading and overriding, you must know the concept of polymorphism. Now let’s dive deep into both overloading and overriding and understand the concepts clearly with some simple examples.
#Apa itu overriding dan overloading code#
Method Overloading Method Overriding Method with same name but different number of arguments Method with same name and same number of arguments Inheritance is optional Inheritance required Takes place in methods within a class Methods reside in different classes Can be done within a class At least 2 classes are required Binding of overloaded methods is done at compile-time hence it is part of compile-time polymorphism Binding of overridden methods is done at run-time hence it is part of run-time polymorphism Static method can be overloaded Static methods cannot be overridden Increases code reusability Used in implementation of specific scenarios Relates with Polymorphism Relates with Inheritance
The child class method will override the parent class method.īelow is a table that points out the differences between method overloading and method overriding. Method overriding allows a parent class and a child class to have methods with the same name and same parameters. What is the difference between method overloading and method overriding? Method overloading allows multiple methods in the same class to have the same name but different parameters.
