How to retrieve last 90 days friday dates?

Just to give you an idea (since you tagged JAVA) , in JAVA this can be accomplished using Date API’s. For testing i was just checking for 5 weeks , you could go all the way to 90 weeks. Please note that this provides an idea , can it be optimized , possibly yes

public static void main(String[] args) {
    try {
        LocalDateTime localDateTime = LocalDate.now().atStartOfDay();
        DayOfWeek dotw = localDateTime.getDayOfWeek();
        String dayOfTheWeek = dotw.name();

        for (int daysOfTheWeek = 1; daysOfTheWeek < 7; daysOfTheWeek++) {
            if (dayOfTheWeek.equals(DayOfWeek.FRIDAY.name())) {
                break;
            } else {
                localDateTime = LocalDate.now().atStartOfDay().minusDays(daysOfTheWeek);
                dotw = localDateTime.getDayOfWeek();
                dayOfTheWeek = dotw.name();
            }
        }
        ArrayList<LocalDate> localDates = new ArrayList<LocalDate>();

        for (int weekCount = 0; weekCount < 5; weekCount++) {
            localDates.add(localDateTime.minusWeeks(weekCount).toLocalDate());
        }
        System.out.println(localDates);

    } catch (final Throwable t) {
        t.printStackTrace();
    }
}
