What are some common mistakes when using static classes?

What are some common mistakes when using static classes?

Some common mistakes include not understanding the implications of state, overusing static classes, and not considering testability.

Can you explain why overusing static classes is a mistake?

Overusing static classes can lead to tightly coupled code, making it harder to maintain and test. It can also hinder flexibility.

What are the alternatives to using static classes?

Alternatives include using instance classes, dependency injection, or service locators to promote better design and testability.

How can I refactor my code to reduce static class usage?

You can start by identifying static methods that can be instance methods, then gradually refactor them to use dependency injection.

Are there any best practices for using static classes?

Yes, use static classes for utility functions, keep them stateless, and ensure they don't manage shared state.
