What are the differences between generics and non-generics in programming?

What are the differences between generics and non-generics in programming?

Generics allow you to write flexible and reusable code by defining classes or methods with a placeholder for data types. Non-generics, on the other hand, use specific data types, which can lead to code duplication and less flexibility.

Can you give me an example of generics in action?

Sure! In Java, you might have a generic class like Box<T> that can hold any type of object. You can create a Box<Integer> or a Box<String> without needing separate classes for each type.

What are the advantages of using generics?

Generics provide type safety, reduce code duplication, and improve code readability. They also allow for better performance by eliminating the need for type casting.

Are there any downsides to using generics?

Yes, generics can add complexity to your code and may lead to issues with type erasure in some languages, which can affect runtime behavior.
