Pattern Matching(Deconstructing) using 'match' and 'case'

scala> //PS:99

scala> //psn > a40 > a11

//--------------- Example 1
scala> val lst = Seq(true, false)
lst: Seq[Boolean] = List(true, false)

scala> for (element <- lst) {
     |   element match {
     |     case true => println("This is True")
     |     case false => println("This is False")
     |   }
     | }
This is True
This is False
//--------------- Example 2
scala> 

scala> val lst = Seq(true, false)
lst: Seq[Boolean] = List(true, false)

scala> for (element <- lst) {
     |   element match {
     |     case true => println("This is True")
     |   }
     | }
<console>:42: warning: match may not be exhaustive.
It would fail on the following input: false
                element match {
                ^
This is True
