//Extracting Values from Optional in Scala
//a. This works well if you have a defined value for your else
val value = Some("Data")
value.getOrElse("No Value")

//b Using match you can extract the value and do anything you want with it
value match {
  case Some(i) => println(s"There is a value $i")
  case _ => println("There is nothing in value")
}

//b.ii -  The values can be extracted into other collections
var finalValue = List[String]()
value match {
  case Some(i) => finalValue ::= i
  case _ => println("There is nothing in value")
}
