Startingtime：

小时：15 分钟：50 第二：00

Finishtime：

小时：17 分钟：14 第二：23

结果：1小时24分23秒

编辑：这是我到目前为止所做的，这是我的问题的计算

public static void main(String[] args) 
{
    Scanner in = new Scanner(System.in);
    System.out.println("Starttime:");
    System.out.println("---------");

    System.out.print("Hour: ");
    int HourS = in.nextInt();
    System.out.print("Minute: ");
    int minuteS = in.nextInt();
    System.out.print("Second: ");
    int secondS = in.nextInt();


    System.out.println("\t");

    System.out.println("Finishtime:");
    System.out.println("------------");

    System.out.print("Hour: ");
    int hourF = in.nextInt();
    System.out.print("Minute: ");
    int minuteF = in.nextInt();
    System.out.print("Second: ");
    int secondM = in.nextInt();

Answer 1

使用JodaTime - 它做得很棒。

http://joda-time.sourceforge.net/

这个简单的例子计算两个时间戳之间的差异，并将其打印成人类可读的：

    String a = "00:01:09:340";
    String b = "00:02:03:430";

    DateTimeFormatter format = DateTimeFormat.forPattern("HH:mm:ss:SSS");
    DateTime oldTime = DateTime.parse(a, format);
    DateTime newTime = DateTime.parse(b, format);
    Interval interval = new Interval(oldTime, newTime);

    System.out.println(new StringBuffer("hours: ").append(interval.toDuration().getStandardHours())
            .append(" minutes: ").append(interval.toDuration().getStandardMinutes()).append(" seconds: ")
            .append(interval.toDuration().getStandardSeconds()).append(" milliseconds: ")
            .append(interval.toPeriod().getMillis()).toString());

该示例将为您提供以下输出：

hours: 0 minutes: 0 seconds: 54 milliseconds: 90

Answer 2

这是ms的差异：

SimpleDateFormat format = new SimpleDateFormat("HH:mm:ss");
Date date = format.parse(time);
Date dateB = format.parse(timeB);
long difference = dateB.getTime() - date.getTime();

您可以将其转换为所需的格式。

Answer 3

public static void main (String [] args) throws Exception
{
    SimpleDateFormat format = new SimpleDateFormat ("'Hour: 'HH' Minute: 'mm' Second: 'ss");

    BufferedReader reader = 
        new BufferedReader (
            new InputStreamReader (System.in));

    System.out.print ("Starting time: ");
    long startingTime = format.parse (reader.readLine ()).getTime ();
    System.out.print ("Finish time: ");
    long finishTime = format.parse (reader.readLine ()).getTime ();

    long delta = finishTime - startingTime;

    long seconds = delta / 1000 % 60;
    long minutes = delta / 60000 % 60;
    long hours = delta / 3600000;

    System.out.println (
        "Result: " + hours + " hour(s) " + minutes + 
        " minute(s) " + seconds + " second(s)");
}

对我来说输出是：

Starting time: Hour: 15 Minute: 50 Second: 00
Finish time: Hour: 17 Minute: 14 Second: 23
Result: 1 hour(s) 24 minute(s) 23 second(s)

Answer 4

您可能需要考虑使用JODA时间，它支持更复杂的日期计算方法。
