Scala Language Futures Putting the Future Together
Example
The previous examples demonstrated the individual features of a Future, handling success and failure cases. Usually, however, both features are handled much more tersely. Here's the example, written in a neater and more realistic way:
object Calculator {
def calculateAndReport(a: Int, b: Int) = {
val eventualQuotient = FutureDivider divide(a, b)
eventualQuotient map {
quotient => println(s"Quotient: $quotient")
} recover {
case ex: ArithmeticException => println(s"It failed with: ${ex.getMessage}")
}
}
}
