如何在两个日期之间获取日期?
这是我的约会对象:
val dateFrom = "01 Jan, 1970"
val dateTill = "01 Jan, 2016"
日期范围:
def getLocalDate(date: String): LocalDate = {
LocalDate.parse(date, format.DateTimeFormatter.ofPattern("dd MMM, yyyy"))
}
def isDateBetWeenRange(from: String, till: String, date: String): Boolean = {
val fromDate = getLocalDate(from)
val tillDate = getLocalDate(till)
val myDate = getLocalDate(date)
myDate.isBefore(tillDate) && myDate.isAfter(fromDate)
}
我想查看我的日期是否在日期范围之间。
这就是我的尝试:
val date = "01 Jan, 2010"
println(isDateBetWeenRange("01 Jan, 2000", "01 Jan, 2016", "01 Jan, date))
但是,如果日期与直到日期相同,则返回false:
<input type="email" name="email" id= value"" required> <br>

添加一些行为的好处和Scala方法是为LocalDate
添加一个隐式类
例如:
implicit class SLocalDate(val time: LocalDate) {
def isBeforeEq(other: ChronoLocalDate) = !time.isAfter(other)
def isAfterEq(other: ChronoLocalDate) = !time.isBefore(other)
}
现在,在此隐含的范围内,您可以将测试更改为:
myDate.isBeforeEq(tillDate) && myDate.isAfterEq(fromDate)

你可以调整你的功能:
(myDate.isBefore(tillDate) && myDate.isAfter(fromDate)) ||
myDate.isEqual(tillDate) ||
myDate.isEqual(fromDate)
