What is the real-world usage of the Factory Pattern?

The Factory Pattern is used to create objects without specifying the exact class of the object that will be created. It's commonly used in scenarios where a system needs to be independent of how its objects are created, composed, and represented.

Can you give me an example of where this pattern is applied?

Sure! A common example is in GUI frameworks where different types of buttons (like Windows, Mac, or Linux buttons) need to be created. The Factory Pattern allows the framework to create the appropriate button type based on the operating system without the client needing to know the specifics.

What are the benefits of using the Factory Pattern?

The benefits include improved code maintainability, easier testing, and the ability to introduce new types of objects without altering existing code.

Are there any drawbacks to using this pattern?

Yes, it can introduce complexity and may lead to over-engineering if used in simple scenarios where direct instantiation would suffice.
