Question

我目前正在尝试将长时间转换为剩余时间。我有一个

long remaining = XXXX

长到某个特定日期的毫秒数。例如：3,600,000应该导致int周= 0，天= 0，小时= 1，分钟= 0，秒= 0 我怎么能把它转换成这么久才能得到5个整数：

int weeks;
int days;
int hours;
int minutes;
int seconds;

提前谢谢！

Answer 1

首先，我建议将秒数，分钟，小时等中的ms数定义为常数

static final int SECOND = 1000;        // no. of ms in a second
static final int MINUTE = SECOND * 60; // no. of ms in a minute
static final int HOUR = MINUTE * 60;   // no. of ms in an hour
static final int DAY = HOUR * 24;      // no. of ms in a day
static final int WEEK = DAY * 7;       // no. of ms in a week

然后，您可以使用基本划分（/）和模数（%）操作来找到您需要的内容。

long remaining = XXXX;

int weeks   = (int)( remaining / WEEK);
int days    = (int)((remaining % WEEK) / DAY);
int hours   = (int)((remaining % DAY) / HOUR);
int minutes = (int)((remaining % HOUR) / MINUTE);
int seconds = (int)((remaining % MINUTE) / SECOND);

对不起，我不想批评太多，我仍然从其他答案中得知，很容易编写难以阅读的代码或编写错误结果的拼写错误代码。 DirtyDev，我知道您可能不被允许使用Duration，但是对于其他任何人：

    long remaining = 3_600_000;

    Duration remainingTime = Duration.ofMillis(remaining);
    long days = remainingTime.toDays();
    remainingTime = remainingTime.minusDays(days);
    long weeks = days / 7;
    days %= 7; // or if you prefer, days = days % 7;
    long hours = remainingTime.toHours();
    remainingTime = remainingTime.minusHours(hours);
    long minutes = remainingTime.toMinutes();
    remainingTime = remainingTime.minusMinutes(minutes);
    long seconds = remainingTime.getSeconds();

    System.out.println("" + weeks + " weeks " + days + " days "
            + hours + " hours " + minutes + " minutes " + seconds + " seconds");

打印：

0 weeks 0 days 1 hours 0 minutes 0 seconds

它并不完美，但我相信它既可读又正确且强大。 Duration的意思是从几小时到几纳秒，所以我们仍然需要“手工”做几周。

新年快乐。

这应该做你想要的。

    long inputTimeInMilliseconds = 93800000;
    long milliseconds = inputTimeInMilliseconds % 1000;
    long seconds =  (inputTimeInMilliseconds / 1000) % 60 ;
    long minutes =  ((inputTimeInMilliseconds / (1000*60)) % 60);
    long hours   =  ((inputTimeInMilliseconds / (1000*60*60)) % 24);
    long days =  ((inputTimeInMilliseconds / (1000*60*60*24)) % 7);
    long weeks = (inputTimeInMilliseconds / (1000*60*60*24*7));

    String remainingTime = "time:"+weeks+":"+days+":"+ hours+":"+minutes+":"+seconds+":"+milliseconds;
    System.out.println(remainingTime);
