Extract numbers from String Array in Scala

Question

I'm new to Scala and unsure of how to achieve the following

I have the String

val output = "6055039\n3000457596\n3000456748\n180013\n"

I want to extract the numbers separated by \n and store them in an Array

output.split("\n").map(_.toInt) But this isn't really a good question for SO. Please read this page for future reference: stackoverflow.com/help/how-to-ask — Dima

output.split("\n").map(_.toInt)

Or only

output.split("\n")

if you want to keep the numbers in String format. Note that .toInt throws. You might want to wrap it accordingly.
