I have two dates in milliseconds.
I need to recover every day of that period to make an insert in the database. I thought I’d do one for each day of that period, but I have no idea how to do it!

java android datetime date

  • These dates are what? Values long obtained by System.currentTimeMillis()?

You can do this by using the API from java 8:

long a = ...;
long b = ...;
Instant ia = Instant.ofEpochMilli(a);
Instant ib = Instant.ofEpochMilli(b);
LocalDate lda = LocalDateTime.ofInstant(ia, ZoneId.of("Z")).toLocalDate();
LocalDate ldb = LocalDateTime.ofInstant(ib, ZoneId.of("Z")).toLocalDate();

List<LocalDate> dates = new ArrayList<>();
for (LocalDate ld = lda; !ld.isAfter(ldb); ld = ld.plusDays(1)) {
    dates.add(ld);
}

See more about this in that other question.
