what’s the error message if you don’t change to

Any

?

That i need to specify the type, but i want a generic like in java, for example only Validator type without passing type, is it possible?

you need to update

validateForm

to

fun <T> validateForm(validator: Validator<T>) {}

Alright nice, in java form is not possible alright? Without pass arg type?

not sure, I guess not

ok thank you!!!

even though type erasure is still a thing at runtime (because of the JVM), Kotlin explicitely forbids erasing type at compile time to avoid ambiguities.

Nice explanation, thank you
