scala match default

In Scala, the match expression can have a default case to handle unmatched patterns. The default case is used when none of the previous cases match the input value. Here's an example of how to use the default case in a match expression in Scala:

val input: String = "unknown"

val result = input match {
  case "case1" => "Result for case 1"
  case "case2" => "Result for case 2"
  case _ => "Default result"

println(result) // Output: Default result

In the above example, if the input value matches neither "case1" nor "case2", the default case (_) will be executed, and the result will be "Default result" [[SOURCE 1]].
