Answers
In Scala, Either is an abstract class. It is used to represent one value of two possible types. It takes two type parameters: Either[A,B].
It exactly have two subtypes: Left and Right. If Either[A,B] represents an instance A that means it is Left. If it represents an instance B that means it is Right.
