我java.util.Date在Scala中使用Java的类,想要比较一个Date对象和当前时间.我知道我可以使用getTime()来计算delta:

(new java.util.Date()).getTime() - oldDate.getTime()

但是,这只留下了一个long代表毫秒.是否有更简单,更好的方式来获得时间增量？

我试图计算两者之间的差异LocalDateTime.

输出必须是格式y years m months d days h hours m minutes s seconds.这是我写的:

import java.time.Duration;
import java.time.Instant;
import java.time.LocalDateTime;
import java.time.Period;
import java.time.ZoneId;

public class Main {

    static final int MINUTES_PER_HOUR = 60;
    static final int SECONDS_PER_MINUTE = 60;
    static final int SECONDS_PER_HOUR = SECONDS_PER_MINUTE * MINUTES_PER_HOUR;

    public static void main(String[] args) {
        LocalDateTime toDateTime = LocalDateTime.of(2014, 9, 9, 19, 46, 45);
        LocalDateTime fromDateTime = LocalDateTime.of(1984, 12, 16, 7, 45, 55);

        Period period = getPeriod(fromDateTime, toDateTime); …
