Learn Java from Scratch - A Beginner's Guide - Step 07 - Understanding Inheritance - Why Do We Need It?

The video tutorial introduces the concept of inheritance in object-oriented programming (OOP). It begins by creating a simple Person class and a Student class, highlighting the issue of code duplication. The tutorial then explains how inheritance can solve this problem by allowing the Student class to extend the Person class, thereby reusing code and reducing maintenance efforts. The video demonstrates the implementation of inheritance and discusses its benefits and limitations, emphasizing the importance of using inheritance only when there is a clear 'is-a' relationship between classes.
