Solution

The concept we use for the implementation of late binding is known as Polymorphism.

Here are the steps to understand this concept:

  1. Polymorphism: This is a principle in object-oriented programming that allows objects of different types to be treated as objects of a parent type. It's the ability of one object to take on many forms. The most common use of polymorphism in OOP occurs when a parent class reference is used to refer to a child class object.

  2. Late Binding: Also known as dynamic binding, late binding in polymorphism happens when the method to be invoked is decided at runtime instead of at compile time. It helps in overriding the methods, which means the method that belongs to the class of the object will be executed.

  3. Implementation: To implement late binding, you would define a method in a parent class and override it in the child class. You can then use a parent class reference to call the method. The specific method that is called is determined at runtime based on the actual type of the object being referred to.

In summary, we use the concept of Polymorphism for the implementation of late binding in object-oriented programming.
