How to call a method n times in Scala?

Question

I have a case where I want to call a method n times, where n is an Int. Is there a good way to do this in a \"functional\" way in Scala?

case class Event(name: S         


        

Answer 1

With recursion:

def repeat(n: Int)(f: => Unit) { 
  if (n > 0) {
    f
    repeat(n-1)(f)
  }
}

repeat(event.quantity) { queue.enqueue(event.value) }
