Object-Oriented Programming (OOP) has become an integral part of modern software programming, and the concept of code reuse is a key factor in this. Reuse enables developers to quickly build on existing projects without needing to write a large amount of new code from scratch. One key OOP feature used as a reuse mechanism is inheritance.   Inheritance describes how objects can acquire properties from parent objects, allowing extended classes to share behaviors and properties with their base class without needing to reconstruct that behavior every time. This not only helps teams develop more quickly, but also foster code integrity and maintainability. Other important OOP concepts that help developers achieve reuse include polymorphism, encapsulation, and interfaces.
