What is Options in Scala

Question

Can someone explain the function of Options in Scala?

Answer 1

Hey,

A Scala Option is a kind of a container. It can hold zero or one element of a type. When it holds a value, it holds Some[T]; otherwise, it holds a None object.

scala> val o:Option[Int]=Some(7)

o: Option[Int] = Some(7)

scala> val o1:Option[Int]=None

o1: Option[Int] = None
