如何过滤Scala映射列表值

val students = List(
  Map("name" -> "Alice", "score" -> 85),
  Map("name" -> "Bob", "score" -> 75),
  Map("name": "Charlie", "score" -> 95)
)

val highScoreStudents = students.filter(_.get("score").exists(_ > 80))
println(highScoreStudents)

val nameFilter = "Alice"
val filteredStudents = students.filter(_.get("name").exists(_ == nameFilter))
println(filteredStudents)

val highScoreStudents = students.filter(_.get("score").exists(_.getOrElse(0) > 80))
println(highScoreStudents)

val highScoreStudents = students.filter {
  case student if student.get("score").exists(_.asInstanceOf[Int] > 80) => true
  case _ => false
}
println(highScoreStudents)
