What are the differences between generics and collections?

Can you explain the differences between generics and collections in programming?

Sure! Generics allow you to define classes, methods, or interfaces with a placeholder for the data type, while collections are data structures that hold groups of objects.

Why would I use generics instead of just using collections?

Using generics provides type safety, meaning you can catch type errors at compile time rather than at runtime, which is a common issue with collections.

Can you give me an example of how generics work?

Absolutely! For instance, in Java, you can create a generic class like Box<T> that can hold any type of object, such as Box<Integer> or Box<String>.

What are some common collections in programming?

Common collections include lists, sets, and maps. Each serves different purposes, like storing ordered items or unique elements.
