Java 获取一定时间范围内的日期序列

 1     String startday = "20150225";
 2         String endday = "20150308";
 3         ArrayList<String> daysarr = new ArrayList<String>();
 4         SimpleDateFormat sdf = new SimpleDateFormat("yyyyMMdd");
 5         try {
 6             Date enddate = sdf.parse(endday);
 7             Date temp = sdf.parse(startday);
 8             int onedaylength = 86400000;
 9             while(temp.before(enddate)){
10                 daysarr.add(sdf.format(temp));
11                 long timestamp = temp.getTime();
12                 timestamp += onedaylength;
13                 temp = new Date(timestamp);
14             }
15         } catch (ParseException e) {
16             // TODO Auto-generated catch block
17             e.printStackTrace();
18         }
