Timer - counting down and displaying result in specific format

Question

I have counter, you set a date, and then you can get time to this date, but I need display it in chosen format.

EG: If I have 1 day, 13 hours, 43 minutes and 30 seconds left, and set format to:

"You have: #d# days, #h# hours, #m# minutes to die"

Then just display:

"You have 1 day, 13 hours, 43 minutes to die"

But if you set format to:

"You have: #h# hours, #m# minutes to die"

Then I need display:

"You have 37 hours, 43 minutes to die"

(so missing type (days) are converted to other (hours))

I have this code: PS: S,M,H,D,W that just second in milliseconds, minutes in milliseconds etc...

public static String getTimerData(long time, String format) {
    int seconds = -1, minutes = -1, hours = -1, days = -1, weeks = -1;
    if (format.contains("#s#")) {
        seconds = (int) (time / S);
    }
    if (format.contains("#m#")) {
        if (seconds == -1) {
            minutes = (int) (time / M);
        } else {
            minutes = (seconds / 60);
            seconds %= 60;
        }
    }
    if (format.contains("#h#")) {
        if (minutes == -1) {
            hours = (int) (time / H);
        } else {
            hours = (minutes / 60);
            minutes %= 60;
        }
    }
    if (format.contains("#d#")) {
        if (hours == -1) {
            days = (int) (time / D);
        } else {
            days = (hours / 24);
            hours %= 24;
        }
    }
    if (format.contains("#w#")) {
        if (days == -1) {
            weeks = (int) (time / W);
        } else {
            weeks = (days / 7);
            days %= 7;
        }
    }
    return format.replace("#w#", Integer.toString(weeks)).replace("#d#", Integer.toString(days)).replace("#h#", Integer.toString(hours)).replace("#m#", Integer.toString(minutes)).replace("#s#", Integer.toString(seconds));
}

And... any better way to do that?

DateTimeFormatter formatter = DateTimeFormatter.ofPattern("yyyy MM dd");
String text = date.toString(formatter);
LocalDate date = LocalDate.parse(text, formatter);

or, if you're not using java8 here

I need something without using other API. (I writing something small, and only as add-on) – user2250333 Feb 15 '14 at 13:11
Java 8 is not an "other API". – bobbel Feb 15 '14 at 13:13
Ach... I thought this is "joda-time". But I must use java 7 ;/ – user2250333 Feb 15 '14 at 13:18
@user2250333 it is there in java7 as well as java6, java 5, etc – Martin Asenov Feb 15 '14 at 14:16
@MartinAsenov Eclipse can't find that – user2250333 Feb 15 '14 at 14:19

@MartinAsenov But that just displays a date, I need something to counting down like: `You have 3 hours and 30 minutes to die`, or `You have 210 minutes to die` where first using `You have #h# hours and #m# minutes to die` and second using `You have #m# minutes to die` pattern. – user2250333 Feb 15 '14 at 16:56
This Answer does not address the Question. – Basil Bourque Mar 11 '16 at 06:54

Joda-Time

If your goal is the words spelling out "1 day, 13 hours, and 43 minutes", then Joda-Time has a class exactly for that purpose: PeriodFormatterBuilder. Using that class is easier that trying to write your own. See examples in other answers such as this one and this one.

java.time.*

The new java.time.* package in Java 8 may have something similar given that it is inspired by Joda-Time. Perhaps the DateTimeFormatterBuilder class in the java.time.format package.
