YearMonthDay is almost deprecated. Converting to
LocalDate made this pretty easy:
YearMonthDay today = new YearMonthDay();
LocalDate todayLd = new LocalDate(today);
int dow = todayLd.getDayOfWeek();
LocalDate firstOfWeek = todayLd.minusDays(dow);
LocalDate lastOfWeek = firstOfWeek.plusDays(
DateTimeConstants.DAYS_PER_WEEK);
DateTimeFormatter dtf = DateTimeFormat.fullDate();
System.out.println("beginning of this week is " +
+ dtf.print(firstOfWeek)
+ "; end of this week is " + dtf.print(
lastOfWeek));
