How to validate a 10-digit phone number with hyphens (e.g. 333-555-1234) using RegEx in Scala

Answer 1

import scala.util.matching.Regex

object PhoneNumberValidator extends App {
  val phoneNumber = "333-555-1234"
  val pattern: Regex = """^\d{3}-\d{3}-\d{4}$""".r

  pattern.findFirstIn(phoneNumber) match {
    case Some(_) => println("Valid phone number format")
    case None => println("Invalid phone number format")
  }
}



/*
run:

Valid phone number format
 
*/
