java中获取List集合中最大的日期时间

public class MaxDateTest {
    public static void main(String[] args) {
        List<Date> dates = Lists.newArrayList();
        dates.add(new DateTime().withDayOfMonth(1).toDate());
        dates.add(new DateTime().withDayOfMonth(2).toDate());
        dates.add(new DateTime().withDayOfMonth(3).toDate());

        Date minDate = Collections.min(dates);
        Date maxDate = Collections.max(dates);

        System.out.println(minDate);
        System.out.println(maxDate);
    }
}

Date max = Collections.max(dateList)

输出：
