The term “super()” appears in various programming languages, primarily within the context of object-oriented programming adn inheritance. It serves a crucial role in allowing subclasses to access and utilize methods and properties from their parent classes. Understanding its usage is essential for effective code reuse and maintaining a clear class hierarchy.
“super()” in Java
In Java, super() is used to call the constructor of the parent class from a subclass.This is particularly critically important when the parent class constructor requires arguments. It can also be used to access methods and variables of the parent class that have been overridden in the subclass [[3]].
I don’t understand when to use the super() call?
For example,if a subclass needs to extend the functionality of a parent class method,it can override the method in the subclass and then use super.methodName() to call the original method from the parent class. This allows the subclass to add its own behavior while still leveraging the existing functionality of the parent class.
“super()” in Python
Python’s super() function is primarily used in the context of multiple inheritance. It provides a way to call methods from parent classes in a predictable order,following the method resolution order (MRO) [[2]]. While it can be used with single inheritance, it’s generally considered unnecessary overhead in such cases.
The primary benefit of super() in Python is its ability to handle complex inheritance hierarchies and ensure that methods are called in the correct order, even when multiple parent classes define methods with the same name.This helps to avoid ambiguity and maintain a clear and consistent behavior.
