java.util.UUID.fromString not checking length

Question

When I looked into the implementation of java.util.UUID.fromString, I found that it doesn\'t check for the UUID length. Is there any particular reason for this?

Answer 1

A copy of ams's answer but for scala xD

def isValidUuid(uuid: String): Boolean =
    try uuid != null && UUID.fromString(uuid).toString.equals(uuid)
    catch {
      case e: IllegalArgumentException => false
    }
