How do I initialize these arrays?
I want to have a class that stores three sets of 30 Foos each. I can declare them as arrays of Foo but I don't know how I can initialize them (give them default values) with 30 elements.
data class Container (
val first: Array,
val second: Array,
val third: Array,
)

data class Foo (val a: Int, val b: Int)
