In this video, we dive deep into Java Generics and understand how the extends keyword works with generics (bounded types).

If you’ve ever been confused about:

Why we use Generics in Java
How type safety actually works
What extends means in Generics
How to restrict types in a class or method

Then this video is for you.

This is not a surface-level explanation — we break everything down using first principles, so you can truly understand what’s happening behind the scenes.
