根据1,2,3,4,5,6,7 --> 对应 的星期的英文

 val code1=6
    val day =code1 match {
      case 1 => "monday"
      case 2 => "tuesday"
      case 3 => "wednesday"
      case 4 => "thursday"
      case 5 => "friday"
      case 6 => "saturday"
      case 7 => "sunday"

      case _=>"该星期数不存在"
    }
    println(day)

 val m1 =Map((1,"monday"),(2,"tuesday"),(3,"wednesday"),(4,"thursday"),(5,"friday"),(6,"saturday"),(7,"sunday"))
    println(m1(30))

 val t0 =(3)
    val t1 =(2,3)
    val t2 =(2,3,4)
    //P220
    //求长方形，梯形，正方形的面积
    def patterTuple(x:Any) =x match {
      case (a) =>println("正方形的面积")
      case (a,b) =>println("长方形的面积")
      case (a,b,c) =>println(s"梯形面积${a}")
      case _ => println("未知")
    }
    patterTuple(t0)
    patterTuple(t1)
    patterTuple(t2)
