An example of an AI chatbot conversation about type parameters in various programming languages.
How do type parameters work in different programming languages?
Type parameters allow functions and classes to operate on types specified at runtime. Languages like Java, C#, and TypeScript use generics for this.
Can you give me an example in Java?
Sure! In Java, you can define a generic class like this: class Box<T> { private T item; public void setItem(T item) { this.item = item; } }.
What about in Python?
Python uses type hints with generics. You can use from typing import TypeVar to create a type variable, like T = TypeVar('T').
Are there any languages that don't support type parameters?
Yes, some languages like JavaScript and PHP (prior to version 7) do not have built-in support for type parameters.
