I'm new to Scala. I have a Scala function, and one of its arguments uses "Option":
def generateTimeSnippet(startOfSentence: Double, endOfSentence: Option[Double]): (Double, Option[Double]) = {
...
}
When I call this function, I give literal values to the arguments:
val snippets = generateTimeSnippet(startOfSentence = 10d, endOfSentence = 20.5)
But this results in a type mismatch error: "type mismatch; found : Double(10.0) required: Option[Double]"
I find this very odd. Why is this happening? Am I not supposed to be allowed to use Doubles for an argument that is defined as Option[Double]?
Of course, for an argument of the type Option[Double]
, you can not send in the type Double
. They are different types.
You can send in Some(20.5)
which is of the type Option[Double]
