我在另一个答案中提到了这一点，但你可以这样做:

public static Map<TimeUnit,Long> computeDiff(Date date1, Date date2) {
    long diffInMillies = date2.getTime() - date1.getTime();
    List<TimeUnit> units = new ArrayList<TimeUnit>(EnumSet.allOf(TimeUnit.class));
    Collections.reverse(units);
    Map<TimeUnit,Long> result = new LinkedHashMap<TimeUnit,Long>();
    long milliesRest = diffInMillies;
    for ( TimeUnit unit : units ) {
        long diff = unit.convert(milliesRest,TimeUnit.MILLISECONDS);
        long diffInMilliesForUnit = unit.toMillis(diff);
        milliesRest = milliesRest - diffInMilliesForUnit;
        result.put(unit,diff);
    }
    return result;
}

输出类似Map:{DAYS=1, HOURS=3, MINUTES=46, SECONDS=40, MILLISECONDS=0, MICROSECONDS=0, NANOSECONDS=0}，单位是有序的。

由您决定如何根据目标语言环境对这些数据进行国际化。

这个主题已经被很好地覆盖了，我只是想分享我的函数，也许你可以使用这些函数，而不是导入整个库。

    public long getSeconds(ms) {
        return (ms/1000%60);
    }
    public long getMinutes(ms) {
        return (ms/(1000*60)%60);
    }
    public long getHours(ms) {
        return ((ms/(1000*60*60))%24);
    }

    long startTime = System.currentTimeMillis();
    // do your work...
    long endTime=System.currentTimeMillis();
    long diff=endTime-startTime;       
    long hours=TimeUnit.MILLISECONDS.toHours(diff);
    diff=diff-(hours*60*60*1000);
    long min=TimeUnit.MILLISECONDS.toMinutes(diff);
    diff=diff-(min*60*1000);
    long seconds=TimeUnit.MILLISECONDS.toSeconds(diff);
    //hour, min and seconds variables contains the time elapsed on your work

乔达时间

使用Joda-Time:

DateTime startTime = new DateTime();

// do something

DateTime endTime = new DateTime();
Duration duration = new Duration(startTime, endTime);
Period period = duration.toPeriod().normalizedStandard(PeriodType.time());
System.out.println(PeriodFormat.getDefault().print(period));

手工划分，或者使用SimpleDateFormat API。

long start = System.currentTimeMillis();
// do your work...
long elapsed = System.currentTimeMillis() - start;
DateFormat df = new SimpleDateFormat("HH 'hours', mm 'mins,' ss 'seconds'");
df.setTimeZone(TimeZone.getTimeZone("GMT+0"));
System.out.println(df.format(new Date(elapsed)));

Edit by Bombe:评论中显示，这种方法只适用于较短的持续时间(即少于一天)。

对于一小时以内的小时间，我更喜欢:

long millis = ...

System.out.printf("%1$TM:%1$TS", millis);
// or
String str = String.format("%1$TM:%1$TS", millis);

对于较长的间隔:

private static final long HOUR = TimeUnit.HOURS.toMillis(1);
...
if (millis < HOUR) {
    System.out.printf("%1$TM:%1$TS%n", millis);
} else {
    System.out.printf("%d:%2$TM:%2$TS%n", millis / HOUR, millis % HOUR);
}
