获取两个日期之间的日期列表

Question

我正在使用JDateChooser,我正在制作一个程序,输出所选日期之间的日期列表.例如:

date1= Jan 1, 2013  // Starting Date

date2= Jan 16,2013  // End Date

然后它会输出

Jan 2, 2013...
Jan 3, 2013.. 
Jan 4, 2013..

等等......直到它到达结束日期.

我已经完成了我的程序,一旦你单击JDatechooser它上面的日期将自动输出结束日期.(选定日期+ 15天=结束日期)

我下载JCalendar或JDateChooser在这里:http://www.toedter.com/en/jcalendar/

Answer 1

您应该尝试使用Calendar,这将允许您从一个日期走到另一个...

Date fromDate = ...;
Date toDate = ...;

System.out.println("From " + fromDate);
System.out.println("To " + toDate);

Calendar cal = Calendar.getInstance();
cal.setTime(fromDate);
while (cal.getTime().before(toDate)) {
    cal.add(Calendar.DATE, 1);
    System.out.println(cal.getTime());
}

更新

这个例子将包括toDate.您可以通过创建第二个日历来解决这个问题,该日历充当lastDate和减去它的一天......

Calendar lastDate = Calendar.getInstance();
lastDate.setTime(toDate);
lastDate.add(Calendar.DATE, -1);

Calendar cal = Calendar.getInstance();
cal.setTime(fromDate);
while (cal.before(lastDate)) {...}

这将仅为您提供开始日期和结束日期之间的所有日期.

将日期添加到ArrayList

List<Date> dates = new ArrayList<Date>(25);
Calendar cal = Calendar.getInstance();
cal.setTime(fromDate);
while (cal.getTime().before(toDate)) {
    cal.add(Calendar.DATE, 1);
    dates.add(cal.getTime());
}

2018年java.time更新

时间继续前进,事情有所改善.Java 8引入了新的java.timeAPI,它取代了"日期"类,并且应该作为首选使用

LocalDate fromDate = LocalDate.now();
LocalDate toDate = LocalDate.now();

List<LocalDate> dates = new ArrayList<LocalDate>(25);

LocalDate current = fromDate;
//current = current.plusDays(1); // If you don't want to include the start date
//toDate = toDate.plusDays(1); // If you want to include the end date
while (current.isBefore(toDate)) {
    dates.add(current));
    current = current.plusDays(1);
}
