How to round time to the nearest quarter hour in java?

Question

Given today\'s time e.g. 2:24PM, how do I get it to round to 2:30PM?

Similarly if the time was 2:17PM, how do I get it to round to 2:15PM?

Answer 1

You can use this simple code...

int mode = min % 15;
if (mode > 15 / 2) {
    min = 15 - mode;
} else {
    min = 0 - mode;
}
cal.add(Calendar.MINUTE, min);
