How to get milliseconds?

Question

I'm doing a countdown timer, I got rid of int variable and made long. The following methods how I get hours, minutes and seconds.

public static long getHours(long totalSeconds) {
    return (long) Math.floor(totalSeconds / 3600000);
}

public static long getMinutes(long totalSeconds) {
    return (long) Math.floor((totalSeconds - 3600000 * getHours(totalSeconds)) / 60000);
}

public static long getSeconds(long totalSeconds) {
    return (long) Math.floor(totalSeconds - 3600000 * getHours(totalSeconds) - 60000 * getMinutes(totalSeconds));
}

public static long getMilliseconds(long totalSeconds) {
    return (long) Math.floor(getSeconds(totalSeconds) / 1000);
}

For ms I divided the second by 1000. Now I get time in such format 12:34:56.000. In place of milliseconds are always .000

What is wrong? How to get milliseconds?

`return totalSeconds * 1000`? And by the way: A method `getSeconds` that retrieves the seconds as an argument and obviously shall return these seconds ... Should that method _calculate_ the seconds? — Seelenvirtuose, May 30 '16 at 06:44
if I do return totalSeconds, I get such time 00:00:12.012 etc — P. Dm, May 30 '16 at 06:47
"I get such time 00:00:12.012" In an `int` variable?!? Not possible ... — Seelenvirtuose, May 30 '16 at 06:48
long ms = (long) hrs * 60 * 60 * 1000 + min * 60 * 1000; here hrs and min are integer value — RejoylinLokeshwaran, May 30 '16 at 07:05

"Milli" comes from the Latin language. It means "a thousandth" of something.

Maybe that gives you a hint how you turn a second value into a milli second value.

Hope this will help you:

public static int getHours(int totalSeconds) {
    return  TimeUnit.SECONDS.toMillis(your seconds);
}
