scala编写任意输入一个月份输出它所属的季节

在Scala中，你可以创建一个函数来判断给定的一个月份属于哪个季节。通常，我们把一年分为四个季度，每个季度三个月。以下是判断季节的基本步骤：

def getSeason(month: Int): String = {
  val monthsInEachSeason = List(0 until 3, 3 until 6, 6 until 9, 9 until 12) // 每个季度的月份范围

  for (seasonRange <- monthsInEachSeason) {
    if (month >= seasonRange.head && month <= seasonRange.last) {
      return "春季" if seasonRange == monthsInEachSeason(0)
      return "夏季" if seasonRange == monthsInEachSeason(1)
      return "秋季" if seasonRange == monthsInEachSeason(2)
      return "冬季" if seasonRange == monthsInEachSeason(3)
    }
  }

  throw new IllegalArgumentException(s"Month $month is not valid.")
}

// 示例用法
val month = 7 // 七月
val season = getSeason(month)
println(s"In $month, the season is ${season}.")
