scala for the impatient excercise 4

// ex 2 
val in = new java.util.Scanner(new java.io.File("example.txt"))
val words = scala.collection.mutable.Map[String, Int]()
while (in.hasNext()) {
	val word = in.next().replaceAll("\\W", "")
	val c = words.getOrElse(word, 0) + 1
	words(word) = c
}
for((k,v) <- words) println(k +" : "+ v)

//ex 4
change line 3 with SortedMap

// ex 6
val dayMap = Map(
	"Monday" -> java.util.Calendar.MONDAY,
	"Tuesday" -> java.util.Calendar.TUESDAY,
	"Wednesday" -> java.util.Calendar.WEDNESDAY,
)
for((k,v) <- dayMap) println(k+" : "+v)

//ex 8
