Simple use of akka futures (now part of scala library)

futures.scala

package akkaActors

import scala.concurrent.Await      // enable awaiting a future
import scala.concurrent.duration._ // enable convert in to ms n.seconds
import scala.concurrent.Future     // Future function
import scala.concurrent.ExecutionContext.Implicits.global // import global execution context (implicit way)

object futureTest extends App {

  // Create and begin execution of the Future
  val future = Future {
    Thread.sleep(5000)
    "Yay!"
  }

  for (i <- 1 to 10) {
    Thread.sleep(450)
    println(i)
  }

  // Await the result
  val res = Await.result(future, 10 seconds)
  println(res)

}
