Why is this Map not populating when I'm evaluating this code in Eclipse?
質問
Below code should populate a Map but when I do a val test = userDataMap.get("test").get
the value is null. Whis is this occuring ? This seems to be the correct way of populating a Map ?
var userDataMap = Map.empty[String, List[String]]
userDataMap += ("test" -> List("test"))
