What are generics and how do they work in different programming languages?

Generics are a feature that allows you to write flexible and reusable code. They enable you to define classes, interfaces, and methods with a placeholder for the data type.

Can you give me examples of how generics are implemented in languages like Java and C#?

Sure! In Java, you can define a generic class like this: class Box<T> { private T item; }. In C#, it looks similar: class Box<T> { private T item; }.

Are there any languages that don't support generics?

Yes, some languages like JavaScript and Python do not have built-in support for generics, but they can achieve similar functionality through other means.

What are the benefits of using generics?

Generics provide type safety, reduce code duplication, and improve code readability, making it easier to maintain.
