java - JodaTime - 2 个日期之间每月的天数

Question

我有 2 个这样的约会:

DateTime startingDate = new DateTime(STARTING_YEAR, STARTING_MONTH, STARTING_DAY, 0, 0);
DateTime endingDate = new DateTime(ENDING_YEAR, ENDING_MONTH, ENDING_DAY, 0, 0);

TOTAL_DAYS = Days.daysBetween(startingDate, endingDate).getDays();

很容易知道之间的总天数，但我对 API 一点也不熟悉，想知道是否有一种更简单的方法可以找到两个日期之间每个月的天数，而无需循环和 ifs。

示例:

DateTime startingDate = new DateTime(2000, 1, 1, 0, 0);
DateTime endingDate = new DateTime(2000, 2, 3, 0, 0);

一月为 31，二月为 2。

谢谢!

Answer 1

我终于用循环做到了。

DateTime startingDate = new DateTime(STARTING_YEAR, STARTING_MONTH, STARTING_DAY, 0, 0);
DateTime endingDate = new DateTime(ENDING_YEAR, ENDING_MONTH, ENDING_DAY, 0, 0);
TOTAL_DAYS = Days.daysBetween(startingDate, endingDate).getDays();

DateTime currentDate = startingDate;

System.out.println(currentDate.dayOfMonth().getMaximumValue() - currentDate.dayOfMonth().get() + 1);
currentDate = currentDate.plus(Period.months(1));

while (currentDate.isBefore(endingDate)) { 
     System.out.println(currentDate.dayOfMonth().getMaximumValue());
     currentDate = currentDate.plus(Period.months(1));
 }  
System.out.println(endingDate.dayOfMonth().get());
