获取一段时间内的所有日期

public static List Day(String begin, String end) {
SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd");
    List strDate = new ArrayList();
    strDate.add(begin)
    Calendar calendar = Calendar.getInstance();
    calendar.setTime(sdf.parse(begin))
    boolean bContinue = true;
    while (bContinue) {
        calendar.add(Calendar.DAY_OF_MONTH, 1)
        if (sdf.parse(end).after(calendar.getTime())) {
            strDate.add(sdf.format(calendar.getTime()).toString())
        } else {
            break;
        }
    }
    strDate.add(end)
    return strDate
}
