What are the performance implications of using generics in programming?

Using generics can improve performance by reducing the need for type casting and allowing for more optimized code. However, it can also lead to increased memory usage if not managed properly.

Can you give an example of how generics might affect performance?

Sure! For instance, in a collection class, using generics allows you to store any data type without boxing and unboxing, which can enhance performance.

Are there any scenarios where generics might degrade performance?

Yes, if generics lead to excessive type instantiation or if they are used inappropriately, it can result in slower performance due to increased memory overhead.

How do generics compare to using interfaces in terms of performance?

Generics typically offer better performance than interfaces because they avoid the overhead of type checks and casting, leading to more efficient code execution.
