Overriding vs. Overloading: Know the Difference
By Shumaila Saeed || Updated on December 25, 2023
Overriding involves substituting a method in a subclass with a new version, differing from its parent class implementation. Overloading entails defining multiple methods within the same scope, sharing the same name but varying in parameters.
Key Differences
Overriding occurs in an inheritance hierarchy where a subclass provides a specific implementation for a method that is already defined in its parent class. This process allows a subclass to offer a specialized behavior that is different from the parent class's implementation of the same method.

Overriding is bound to inheritance and is a concept where the child class alters the behavior of a method inherited from the parent class. The signature of the overridden method in the child class must match the parent class's method.

Overriding is utilized to provide specific implementation details in a subclass, thus offering functionality that is more appropriate for the subclass, even though the method's signature remains the same as in the parent class.

Overriding ensures that the subclass can use a method with the same name and signature as the parent class but with a tailored behavior that suits its own needs. This concept is pivotal in achieving polymorphism in object-oriented programming.

Overriding allows for runtime polymorphism in object-oriented programming. The decision about which method implementation to use is made at runtime, depending on the object's actual class.
