Indeed LocalDate is the answer to the problem, but the first day of
week/last day of week is simpler:
YearMonthDay today = new YearMonthDay();
LocalDate todayLD = today.toLocalDate();
LocalDate firstDOW = todayLD.dayOfWeek().withMinimumValue();
LocalDate lastDOW = todayLD.dayOfWeek().withMaximumValue();
