How to convert from from java.util.Map to a Scala Map

Question

A Java API returns a java.util.Map;. I would like to put that into a Map[String,Boolean]

So imagine w

Answer 1

I think I have a partial answer...

If you convert the java map to a scala map with the java types. You can then map it to a scala map of scala types:

val javaMap = new java.util.TreeMap[java.lang.String, java.lang.Boolean]
val temp = new collection.jcl.MapWrapper[java.lang.String,java.lang.Boolean] {
    override def underlying = javaMap
}
val scalaMap = temp.map{
    case (k, v) => (k.asInstanceOf[String] -> v.asInstanceOf[Boolean])
}

The flaw in this plan is that the type of scalaMap is Iterable[(java.lang.String, Boolean)] not a map. I feel so close, can someone cleverer than me fix the last statement to make this work?!
