Creating a random program in Scala

	import scala.collection.mutable.ListBuffer
	import scala.util.Random
	object RandomProgram {
	def process1(): Unit = {
	println("This is process 1 executing")
	}
	def process2(): Unit = {
	println("This is process 2 executing")
	}
	def process3(): Unit = {
	println("This is process 3 executing")
	}
	def main(args: Array[String]): Unit = {
	val processes = new ListBuffer[() => Unit]
	processes += (process1, process2, process3)
	for (process <- Random.shuffle(processes)) process()
	}
	}
	/**
	The program will print all 3 strings but we cannot predict in which order.
	My second run of this program resulted in below output:
	This is process 1 executing
	This is process 3 executing
	This is process 2 executing
