从 Seq[Map] 中过滤掉空 Map

Question

我有这个 Seq[Map[String,String]] ：

Seq(Map("Name"-> "Laura", "City" -> "Paris"), Map("Country" -> "Italy"), Map())

我想删除空地图以便获得：

Seq(Map("Name"-> "Laura", "City" -> "Paris"), Map("Country" -> "Italy"))

请问我该怎么做？

Answer 1

val data = Seq(Map("Name"-> "Laura", "City" -> "Paris"), Map("Country" -> "Italy"), Map())

val dataWithoutEmptyMaps = data.filter(_.nonEmpty)
