How to format a duration in java? (e.g format H:MM:SS)

Question

I\'d like to format a duration in seconds using a pattern like H:MM:SS. The current utilities in java are designed to format a time but not a duration.

Answer 1

This answer only uses Duration methods and works with Java 8 :

public static String format(Duration d) {
    long days = d.toDays();
    d = d.minusDays(days);
    long hours = d.toHours();
    d = d.minusHours(hours);
    long minutes = d.toMinutes();
    d = d.minusMinutes(minutes);
    long seconds = d.getSeconds() ;
    return 
            (days ==  0?"":days+" jours,")+ 
            (hours == 0?"":hours+" heures,")+ 
            (minutes ==  0?"":minutes+" minutes,")+ 
            (seconds == 0?"":seconds+" secondes,");
}
