L17: Subtyping vs inheritance in java | type compatibility & code reuse

Описание: Welcome to Lecture 17 of the course "Programming Concepts using Java" by Prof. Madhavan Mukund.

Video Overview
This lecture revisits two fundamental concepts in Object-Oriented Programming (OOP): subtyping and inheritance. We discuss how subtyping establishes “is-a” relationships and guarantees type compatibility, while inheritance emphasizes code reuse and hierarchical organization. Using examples from data structures such as Queue, Stack, and Deque, we highlight how these concepts can diverge in practice, and why distinguishing between them is crucial for designing effective and maintainable object-oriented systems.
