What are the advantages of using static classes in programming?

Static classes offer several advantages, such as memory efficiency, easier access to methods, and preventing instantiation.

Can you explain how memory efficiency works with static classes?

Sure! Static classes are loaded into memory once, which means they don't require multiple instances, saving memory.

Are there any downsides to using static classes?

Yes, static classes can lead to less flexibility and difficulty in unit testing since they can't be instantiated or mocked.

When should I avoid using static classes?

Avoid static classes when you need polymorphism, inheritance, or when you want to maintain state across instances.
