What is Extractor in Scala? What is the difference between Constructor and Extractor in Scala? What is the use of Extractor in Scala?
Answer / Indrajeet Kumar
An extractor in Scala is a value that can be used to deconstruct a case class instance. Constructors are used for creating new instances, while extractors are used for accessing the values of an existing instance. The primary purpose of extractors is to provide pattern matching functionality in Scala. They allow you to decompose a case class and match its fields during pattern matching.
