Example
Using Try with map, getOrElse and flatMap:
import scala.util.Try
val i = Try("123".toInt) // Success(123)
i.map(_ + 1).getOrElse(321) // 124
val j = Try("abc".toInt) // Failure(java.lang.NumberFormatException)
j.map(_ + 1).getOrElse(321) // 321
Try("123".toInt) flatMap { i =>
Try("234".toInt)
.map(_ + i)
} // Success(357)
Using Try with pattern matching:
Try(parsePerson("John Doe")) match {
case Success(person) => println(person.surname)
case Failure(ex) => // Handle error ...
}
