Core Java Programming Course- Class Inheritance

The video tutorial explains the concept of inheritance in Java, emphasizing its importance for code reusability. It provides examples using simple classes to demonstrate how inheritance allows a subclass to use fields and methods from a superclass. The tutorial includes a practical example with classes representing geometric shapes like Polygon, Triangle, and Rectangle, illustrating the 'is-a' relationship in inheritance. The session concludes with a brief overview of the benefits of inheritance and a preview of future topics.
