What are the common mistakes in the factory design pattern?

What are the common mistakes in the factory design pattern?

Some common mistakes include not using interfaces, failing to encapsulate object creation, and not considering scalability.

Can you explain why using interfaces is important?

Using interfaces allows for better abstraction and flexibility, making it easier to swap implementations without changing the client code.

What about scalability issues?

Scalability issues arise when the factory pattern is not designed to handle an increasing number of product types, leading to a rigid structure.

How can I avoid these mistakes?

To avoid these mistakes, ensure you define clear interfaces, keep your factory classes simple, and plan for future extensions.
