Scala中的Map和Set

Map和Set中常用的一些方法。

var jetset = Set("one","two")
jetset += "three"
println(jetset.contains("four"))
println(jetset.contains("three"))
jetset.foreach(arg => println(arg))
print(jetset.size)

import scala.collection.mutable.Map
val treasureMap = Map[Int,String]()
treasureMap +=(1->"one")
treasureMap +=(2->"two")
treasureMap +=(3->"three")
print(treasureMap(1))
