3. Encapsulation Overview

Encapsulation is one of the fundamental principles of object-oriented programming (OOP) that facilitates the creation of modular and maintainable code. Here, you will explore the significance of Data Hiding, Access Control, Mutator, and Accessor Methods, elucidating their pivotal roles in code maintenance and modularity.

The Final Keyword

The final keyword plays a crucial role in defining classes and controlling inheritance hierarchies. It provides developers with a powerful mechanism to restrict certain aspects of class design.

The usage of final keyword

When a class is declared as final, it indicates that the class cannot be subclassed further. In other words, it serves as the end point of the inheritance hierarchy, disallowing from deriving it.

Example


              12345678910
            
class Example final {
    // Class members and methods
};

//  cannot derive from final base Example
class ExtendedExample: public Example {
    // Class members and methods
};

int main() {}

This feature is especially valuable when you aim to restrict the modification or extension of a specific class, or when you prefer utilizing your class using composition rather than inheritance. There is also other benefits to using it.
