获取正确范围内的 DateTime 倒数 - Joda Time
我想得到日期时间的计数，该计数与乔达时间在正确的范围内。 我现在有这个版本，它只适合检查特定的一天：
public int getIntFatalitiesAtDay(DateTime AtDay) {
int resultCount = 0;
for( Fatality f : fatalities) {
if(Days.daysBetween(f.date, AtDay).getDays() == 0) {
resultCount++;
}
}
return resultCount;
}
当我每天循环抛出时，这很有用。但是现在我按月计算：
for (DateTime iDate = fa.firstDate; iDate.isBefore(fa.lastDate); iDate = iDate.plusMonths(1)) { ... }
现在我想了解该月的死亡人数。 有人可以帮忙吗？
（也是从那一年开始，虽然我也希望看到一个不考虑年份的选项，但这不太重要。）
I want to get the count back of DateTime that where within the correct range with Joda Time.
I have this version at the moment which is only good to check for a specific day:
public int getIntFatalitiesAtDay(DateTime AtDay) {
int resultCount = 0;
for( Fatality f : fatalities) {
if(Days.daysBetween(f.date, AtDay).getDays() == 0) {
resultCount++;
}
}
return resultCount;
}
This was usefull when i looped threw every day. However now i go by months with:
for (DateTime iDate = fa.firstDate; iDate.isBefore(fa.lastDate); iDate = iDate.plusMonths(1)) { ... }
And now i would like to get the count of fatalities that month.
Could someone help?
(Also from that year, althought i would like to see a option aswell where it doesn't look at the year but that's less important.)

Java 的 java.util.Date 类具有用于确定一个日期是在另一个日期之前还是之后的方法。如果将 DateTime 对象转换为 Date 对象，您可以执行以下操作：

java.util.Dateclass has methods for determining if one date is before or after another. If you convert the DateTime objects to Date objects, you can do:
