Ecco un po 'di codice che uso. dtDateTimes
può contenere le date predefinite per le festività (ad es. Festività in UK) e dtConstants
può contenere elementi ricorrenti ai quali si desidera confrontare, ad esempio DateTimeConstants.SATURDAY
.
/**
* Returns a tick for each of
* the dates as represented by the <code>dtConstants</code> or the list of <code>dtDateTimes</code>
* occurring in the period as represented by begin -> end.
*
* @param begin
* @param end
* @param dtConstants
* @param dtDateTimes
* @return
*/
public int numberOfOccurrencesInPeriod(final DateTime begin, final DateTime end, List<Integer> dtConstants, List<DateTime> dtDateTimes) {
int counter = 0;
for (DateTime current = begin; current.isBefore(end); current = current.plusDays(1)) {
for (Integer constant : dtConstants) {
if (current.dayOfWeek().get() == constant.intValue()) {
counter++;
}
}
for (DateTime dt : dtDateTimes) {
if (current.getDayOfWeek() == (dt.getDayOfWeek())) {
counter++;
}
}
}
return counter;
}
/**

public boolean isInPeriod(final DateTime begin, final DateTime end, List<Integer> dtConstants, List<DateTime> dtDateTimes) {
return numberOfOccurrencesInPeriod(begin, end, dtConstants, dtDateTimes) > 0;

Contrassegnare come risposta accettata, perché è vero. Secondo le mie ricerche, non esiste una soluzione semplice. E Jodatime è sicuramente utile. – picca
