使用java对给定的两个日期之间的日期进行遍历

public class SplitTime {
private static List<Date> dateSplit(Date startDate, Date endDate)
        throws Exception {
    if (!startDate.before(endDate))
        throw new Exception("开始时间应该在结束时间之后");
    Long spi = endDate.getTime() - startDate.getTime();
    Long step = spi / (24 * 60 * 60 * 1000);// 相隔天数

    List<Date> dateList = new ArrayList<Date>();
    dateList.add(endDate);
    for (int i = 1; i <= step; i++) {
        dateList.add(new Date(dateList.get(i - 1).getTime()
                - (24 * 60 * 60 * 1000)));// 比上一天减一
    }
    return dateList;
}

public static void main(String[] args) throws ParseException {
    try {
        SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd");
        Date start = sdf.parse("2015-4-20");
        Date end = sdf.parse("2015-5-2");
        List<Date> lists = dateSplit(start, end);
        if (!lists.isEmpty()) {
            for (Date date : lists) {
                System.out.println(sdf.format(date));
            }
        }
    } catch (Exception e) {
    }
}

}

运行结果：
