如何匹配Scala中数组的类型？

def matchArrayType(arr: Array[Any]): String = arr match {
  case _: Array[Int] => "Int数组"
  case _: Array[String] => "String数组"
  case _: Array[Double] => "Double数组"
  case _: Array[Boolean] => "Boolean数组"
  case _: Array[_] => "其他类型数组"
}

val intArray = Array(1, 2, 3)
val stringArray = Array("a", "b", "c")
val doubleArray = Array(1.0, 2.0, 3.0)
val booleanArray = Array(true, false, true)
val otherArray = Array('a', 'b', 'c')

println(matchArrayType(intArray)) // 输出：Int数组
println(matchArrayType(stringArray)) // 输出：String数组
println(matchArrayType(doubleArray)) // 输出：Double数组
println(matchArrayType(booleanArray)) // 输出：Boolean数组
println(matchArrayType(otherArray)) // 输出：其他类型数组
