Описание: Welcome to Lecture 13 of the course "Programming Concepts using Java" by Prof. Madhavan Mukund.

Video Overview
This lecture examines the Java class hierarchy and its role in structuring object-oriented programs. We explore why Java enforces single inheritance (rooted in the Object class) instead of allowing multiple inheritance, to avoid conflicts and ambiguity. The lecture introduces the default methods of the Object class, such as equals() and toString(), and demonstrates how to override these methods effectively to provide customized behavior in user-defined classes. We also discuss method overriding rules, including how the compiler resolves the closest matching signature from top to bottom, and how this ties into polymorphism and dynamic dispatch in Java.
