2. Factory Method Design Pattern | Bad vs Good Example

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)
