從日期到當前日期的日期列表

Question

我正在嘗試獲取scala的日期列表

val savePoint:java.util.Date=                               //olderDate
var days = List[String]()
for (date<-savePoint to java.util.Date.parse("yyyy-MM-dd") by date.plusDays(1)){
    days::=date
}

但出現錯誤

 value to is not a member of java.util.Date

對於Scala，您可以使用Lamma日期（ http://www.lamma.io ）
