is there a collection in kotlin like java's Vector which will default instantiate the instances? i want to create a collection of a generic type (from a class generic param) but don't want to have to pass in a lambda to tell the class how to default initialize. i.e.:

class Foo<StatType> {
    val stats = Vector<StatType>(8)
}

As far as I know, java’s Vector does not create default instances for its elements.
How would this work if StatType didn’t have default constructor?
You can just write:

List(8) { StatType() }

i can't do that because the generic isn't reified. and i assumed java would throw or something if it didn't have a default (it works with the vector, i didn't dig into how though)

[Pavlo Liapota]

`Vector`s constructor accepts initialCapacity. Size of the Vector will still be 0.

[bbaldino]

hmm. i know that with that initialization, i'm able to do stats[index].member and it works fine.

[bbaldino]

nope, sorry. i take that back.

[bbaldino]

you're right, the instance isn't there. so i guess i'm stuck with passing a builder or something either way

You need to pass a builder. You can use a functional type () -> T

cool, that's exactly what i did. thanks.
