[java]将秒数转化为“天时分秒”的格式（转贴+修改）

public class Time {
    // format seconds to day hour minute seconds style
    // Exmplae 5000s will be formatted to 1h23m20s
    public static String toDhmsStyle(long allSeconds) {
        String DateTimes = null;
        
        long days = allSeconds / (60 * 60 * 24);
        long hours = (allSeconds % (60 * 60 * 24)) / (60 * 60);
        long minutes = (allSeconds % (60 * 60)) / 60;
        long seconds = allSeconds % 60;
        
        if (days > 0) {
            DateTimes = days + "d" + hours + "h" + minutes + "m" + seconds + "s";
        } else if (hours > 0) {
            DateTimes = hours + "h" + minutes + "m" + seconds + "s";
        } else if (minutes > 0) {
            DateTimes = minutes + "m" + seconds + "s";
        } else {
            DateTimes = seconds + "s";
        }

        return DateTimes;
    }

    public static void main(String[] args) {
        long mss = 5000;
        String ss = Time.toDhmsStyle(mss);
        System.out.println(ss);
    }
}

输出：

1h23m20s

改进版：

函数：

// change seconds to DayHourMinuteSecond format
    private static String ms2DHMS(long startMs, long endMs) {
        String retval = null;
        long secondCount = (endMs - startMs) / 1000;
        String ms = (endMs - startMs) % 1000 + "ms";

        long days = secondCount / (60 * 60 * 24);
        long hours = (secondCount % (60 * 60 * 24)) / (60 * 60);
        long minutes = (secondCount % (60 * 60)) / 60;
        long seconds = secondCount % 60;

        if (days > 0) {
            retval = days + "d" + hours + "h" + minutes + "m" + seconds + "s";
        } else if (hours > 0) {
            retval = hours + "h" + minutes + "m" + seconds + "s";
        } else if (minutes > 0) {
            retval = minutes + "m" + seconds + "s";
        } else {
            retval = seconds + "s";
        }

        return retval + ms;
    }

调用：

            long startMs = System.currentTimeMillis();
            clearTable(stmt,conn);
            List<String> insertSqls=generateInsertSqlList();
            betachInsert(insertSqls,stmt,conn);
            long endMs = System.currentTimeMillis();
            log.info("It takes "+ms2DHMS(startMs,endMs)+" to fill "+Total+" records.");
