问题描述
我有一个Map,其中的键是一个String,值是一个Int,但表示为String.
I've a Map where the key is a String and the value is an Int but represented as a String.
scala> val m = Map( "a" -> "1", "b" -> "2", "c" -> "3" ) m: scala.collection.immutable.Map[String,String] = Map(a -> 1, b -> 2, c -> 3)现在我要将其转换为Map[String, Int]
推荐答案scala> m.mapValues(_.toInt) res0: scala.collection.immutable.Map[String,Int] = Map(a -> 1, b -> 2, c -> 3)
