In this video, we learn the Factory Method Design Pattern in Java using a very simple real-world example.
We take an ecommerce notification scenario, where an application needs to send messages through different channels like:
SMS
WhatsApp
Email
First, we implement the bad approach using multiple if-else conditions inside the main code.
Then, we improve the design using the Factory Method Pattern, where object creation is moved into a separate factory class.
This makes the code:
✅ cleaner
✅ easier to extend
✅ easier to maintain
✅ flexible for future changes
By the end of this video, you will clearly understand:
What problem Factory Method solves
Why the bad code becomes difficult to manage
How the Factory Method pattern makes code better
📌 Source Code Structure Shown in Video
BAD Version (if-else creation logic)
GOOD Version (Factory Method pattern)
