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

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

Using nested classes can enhance encapsulation and organization. It's best to use them when they are closely related to the outer class.

Can you give an example of when to use a nested class?

Sure! If you have a class Car and a nested class Engine, it makes sense because the engine is specific to that car.

Are there any downsides to using nested classes?

Yes, nested classes can increase complexity and make the code harder to read if overused. Use them judiciously.

How do nested classes affect memory usage?

Nested classes can lead to increased memory usage if they hold references to the outer class, as they create a stronger coupling.
