What are the best practices for using static classes in programming?

Static classes are useful for grouping related methods and properties. Best practices include keeping them simple, ensuring they are stateless, and using them for utility functions.

Can you give me an example of a static class?

Sure! A common example is a Math utility class that contains static methods like Math.max() or Math.min().

What are the downsides of using static classes?

Static classes can lead to tight coupling and make unit testing difficult since they cannot be mocked easily.

When should I avoid using static classes?

Avoid static classes when you need to maintain state, require polymorphism, or when you want to facilitate unit testing.
