Scala: pairs

pairs.scala

// Pairs can be constructed easily using parentheses:
val pair: (Char, Int) = ('c', 1)

// In order to access the two elements of a pair, you can use the accessors `_1` and `_2`:
val theChar = pair._1
val theInt  = pair._2

// Another way to deconstruct a pair is using pattern matching:
pair match {
  case (theChar, theInt) =>
    println("character is: " + theChar)
    println("integer is  : " + theInt)
}
