scala 时间戳比较大小

scala，时间戳比较大小，三个参数：currentTime:String,starTime:String,endTime:String

 def TimeCompare(currentTime:String,starTime:String,endTime:String): Boolean ={
    var flag=false
    val df: DateFormat = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss")
    try {
      val curr:Date=df.parse(currentTime)
      val star: Date = df.parse(starTime)
      val end: Date = df.parse(endTime)
      val cs: Long = curr.getTime - star.getTime
      val ec: Long = end.getTime - curr.getTime
      if (cs >= 0 &&  ec>0) {
        flag=true
      }
    }
    catch {
      case e: Exception => {
      }
    }
    return flag
  }

比较时间是[startime,endtime)的关系，

包含开始的时间，不包含结束的时候。
