从今天开始计算Groovy的年龄 [英] Calculate age in Groovy from today

问题描述

试图弄清楚某人基于他们的bday的年龄。以下代码给出了天数

  def now = new Date（）
 def dob = new Date（ '08/21/1982'）
 
 println now  -  dob 
  

我们可以除以365，但这不完全准确。必须有一个简单的方法来做到这一点，但我似乎无法找到它。有任何想法吗？

解决方案

或者使用Java 8和Groovy 2.3 RC（如果您希望处于最前沿）; - ）

  import java.time。* 
 
 LocalDate today = LocalDate.now（）
 LocalDate birthday = LocalDate.of（1982，Month.AUGUST，8）
 
 Period period = between（birthday，today）
 
 println$ period.years years，
 | $ period.months months，
 | $ period.days days。stripMargin（）
  

Trying to figure out how old someone is based on their bday. The following code gives us the number of days

def now = new Date()
def dob = new Date('08/21/1982')

println now - dob

We could divide by 365 but that isn't entirely accurate. There has to be an easy way to do this but I just can't seem to find it. Any ideas?

解决方案

Or using Java 8 and Groovy 2.3 RC (if you want to be on the bleeding edge) ;-)

import java.time.*

LocalDate today    = LocalDate.now()
LocalDate birthday = LocalDate.of( 1982, Month.AUGUST, 8 )

Period period = Period.between( birthday, today )

println """$period.years years, 
          |$period.months months, 
          |$period.days days""".stripMargin()
