使用java。Java 8中的时间包:

Instant start = Instant.now();
Thread.sleep(63553);
Instant end = Instant.now();
System.out.println(Duration.between(start, end));

输出为ISO 8601 Duration格式:pt1m3.53s(1分3.553秒)。

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);
}

只是为了补充更多信息 如果你想格式化为:HH:mm:ss

0 <= HH <= infinite

0 <= mm < 60

0 <= ss < 60

用这个:

int h = (int) ((startTimeInMillis / 1000) / 3600);
int m = (int) (((startTimeInMillis / 1000) / 60) % 60);
int s = (int) ((startTimeInMillis / 1000) % 60);

我只是现在有这个问题，并解决了这个问题

如果你知道时间差将小于一个小时，那么你可以使用以下代码:

    Calendar c1 = Calendar.getInstance();
    Calendar c2 = Calendar.getInstance();

    c2.add(Calendar.MINUTE, 51);

    long diff = c2.getTimeInMillis() - c1.getTimeInMillis();

    c2.set(Calendar.MINUTE, 0);
    c2.set(Calendar.HOUR, 0);
    c2.set(Calendar.SECOND, 0);

    DateFormat df = new SimpleDateFormat("mm:ss");
    long diff1 = c2.getTimeInMillis() + diff;
    System.out.println(df.format(new Date(diff1)));

结果是:51:00

对于正确的字符串(“1小时，3秒”，“3分钟”，而不是“0小时，0分钟，3秒”)，我写这样的代码:

int seconds = (int)(millis / 1000) % 60 ;
int minutes = (int)((millis / (1000*60)) % 60);
int hours = (int)((millis / (1000*60*60)) % 24);
int days = (int)((millis / (1000*60*60*24)) % 365);
int years = (int)(millis / 1000*60*60*24*365);

ArrayList<String> timeArray = new ArrayList<String>();

if(years > 0)   
    timeArray.add(String.valueOf(years)   + "y");

if(days > 0)    
    timeArray.add(String.valueOf(days) + "d");

if(hours>0)   
    timeArray.add(String.valueOf(hours) + "h");

if(minutes>0) 
    timeArray.add(String.valueOf(minutes) + "min");

if(seconds>0) 
    timeArray.add(String.valueOf(seconds) + "sec");

String time = "";
for (int i = 0; i < timeArray.size(); i++) 
{
    time = time + timeArray.get(i);
    if (i != timeArray.size() - 1)
        time = time + ", ";
}

if (time == "")
  time = "0 sec";

使用java . util . concurrent。TimeUnit，使用这个简单的方法:

private static long timeDiff(Date date, Date date2, TimeUnit unit) {
    long milliDiff=date2.getTime()-date.getTime();
    long unitDiff = unit.convert(milliDiff, TimeUnit.MILLISECONDS);
    return unitDiff; 
}

例如:

SimpleDateFormat sdf = new SimpleDateFormat("yy/MM/dd HH:mm:ss");  
Date firstDate = sdf.parse("06/24/2017 04:30:00");
Date secondDate = sdf.parse("07/24/2017 05:00:15");
Date thirdDate = sdf.parse("06/24/2017 06:00:15");

System.out.println("days difference: "+timeDiff(firstDate,secondDate,TimeUnit.DAYS));
System.out.println("hours difference: "+timeDiff(firstDate,thirdDate,TimeUnit.HOURS));
System.out.println("minutes difference: "+timeDiff(firstDate,thirdDate,TimeUnit.MINUTES));
System.out.println("seconds difference: "+timeDiff(firstDate,thirdDate,TimeUnit.SECONDS));
