Final answer:
The method overriding in object-oriented programming, where a child class method is called instead of a parent class method with the same signature.
Step-by-step explanation:
The concept of method overriding in object-oriented programming, where a method in a derived class (child class) has the same signature as a method in the base class (parent class). When the method is called on an object of the derived class, the overridden method of the child class is used by default instead of the parent class method. This allows for the specialization of behavior in the derived class.
The key points of method overriding are:
Both the parent and child classes have a method with the same name and signature.
The child class provides its implementation of the method, which is used instead of the parent class's implementation when the method is called on an object of the child class.
Method overriding is the mechanism by which a child class method is used by default when a parent class contains a method with the same signature. This feature allows for polymorphism, where a single interface (method signature) can be implemented in different ways by different classes.
