Method Overriding
Method overriding is an object-oriented programming (OOP) concept where a subclass provides a specific implementation of a method that is already defined in its superclass. It allows a child class to modify or extend the behavior of an inherited method, enabling polymorphism and runtime method resolution. This is a fundamental feature in languages that support inheritance, such as Java, C++, and Python.
Developers should learn method overriding to implement polymorphism, where objects of different classes can be treated uniformly through a common interface, enhancing code flexibility and reusability. It is essential in scenarios like creating specialized behaviors in subclasses (e.g., overriding a 'calculateArea' method in geometric shapes) or customizing framework methods (e.g., in GUI event handling). Without it, code would be less modular and harder to maintain in large-scale applications.
