獲取從現在到DateMidnight類之間的剩餘天數

Question

我的到期日期爲DateMidnight類型 - DateMidnight return_due_date並且我想計算從現在開始直到此日期的剩餘天數。

我該如何計算？

DateMidnight documentation

Answer 1

int days = org.joda.time.Days.daysBetween(DateMidnight.now(), yourDueDate).getDays(); 

Answer 2

使用org.joda.time.Days類。它提供了一些daysBetween方法來精確計算你需要的東西。

DateMidnight midnight = return_due_date; // your DateMidnight instance 
DateTime now = new DateTime(); 

int daysBetween = Days.daysBetween(now, midnight).getDays(); 

Answer 3

這是它是如何做：

import org.joda.time.DateMidnight; 
import org.joda.time.DateTime; 
import org.joda.time.Days; 


public class example { 

/** 
* How many days until a certain date. 
*/ 
public static void main(String[] args) { 
    // TODO Auto-generated method stub 
    DateMidnight someDate = new DateMidnight(2013,6,26); 
    System.out.println("An example due date: "+someDate); 
    DateTime timeNow = new DateTime(); 
    System.out.println("The time right now: "+timeNow); 
    int daysToDeadLine = Days.daysBetween(timeNow, someDate).getDays(); 
    System.out.println("Days until deadline: "+daysToDeadLine); 

}} 

我還建議代表您下次再努力一點？ :)
