    Kotlin is also really nice and clean. Especially like how clean the syntax for populating the initial array is. It has a little bit more boilerplate than Python, but still super pleasant compared to what you'd have to do in java 7 or lower.

    import java.util.Scanner

fun main(args: Array<String>) {
    val sc = Scanner(System.`in`)

    val size = sc.nextInt()
    val inputs = Array(size, { sc.nextDouble() })

    println(inputs.count { it > 0.0} / size.toDouble())
    println(inputs.count { it < 0.0} / size.toDouble())
    println(inputs.count { it == 0.0} / size.toDouble())
}
