82. Getting the first and last day of the year

Getting the first and last day of the given year (as a numeric value) can be done via LocalDate and the handy TemporalAdjusters, firstDayOfYear(), and lastDayOfYear(). First, we create a LocalDate from the given year. Next, we use this LocalDate with firstDayOfYear()/lastDayOfYear() as in the following code:

public static String fetchFirstDayOfYear(int year, boolean name) {
  LocalDate ld = LocalDate.ofYearDay(year, 1);
  LocalDate firstDay = ld.with(firstDayOfYear());
  if (!name) {
    return firstDay.toString();
  }
  return DateTimeFormatter.ofPattern("EEEE").format(firstDay);
}

And, for the last day, the code is almost similar:

public static String fetchLastDayOfYear(int year, boolean name) {
  LocalDate ld = LocalDate.ofYearDay(year, 31);
  LocalDate lastDay = ld.with(lastDayOfYear());
  if (!name) {
    return lastDay.toString();
  }
  return DateTimeFormatter.ofPattern("EEEE").format(lastDay);...
