Kotlin array initialization throws null pointer exception
I'm a total beginner with kotlin, and I'm trying to initialize an array using the constructor that accepts a size and a function. This is what I have:

var ary = Array(5, {x -> x + 2})
println(ary[2])


But it's throwing a null pointer exception on the first line. Why is this happening?
