What are some examples of generics in programming?

Can you explain what generics are in programming?

Generics allow you to write flexible and reusable code by defining classes, methods, or interfaces with a placeholder for types.

Can you give me an example of generics in Java?

Sure! In Java, you can create a generic class like this: class Box<T> { private T item; public void setItem(T item) { this.item = item; } public T getItem() { return item; } }.

What about generics in C#?

In C#, you can define a generic method like this: public T GetItem<T>(T item) { return item; }. This method can accept any type.

Are there any downsides to using generics?

Yes, while generics provide type safety and code reusability, they can also lead to complexity and may have performance implications in some cases.
