java 求取某一段时间内的每一天、每一月、每一年

1.求取某一段时间内的每一天

     Date date0 = new SimpleDateFormat("yyyy-MM-dd").parse("2014-01-01");
             Date date1 = new SimpleDateFormat("yyyy-MM-dd").parse("2014-10-03");
             Calendar cal = Calendar.getInstance();
             cal.setTime(date0);
             while(cal.getTime().compareTo(date1)<=0){
             cal.add(Calendar.DAY_OF_MONTH,1);
              list0.add(sdf.format(cal.getTime()));
             }

2.求取某一段时间内的每一月
方法一：

date0 = new SimpleDateFormat("yyyy/MM/dd").parse("2014/01/01");
            Date date1 = new SimpleDateFormat("yyyy/MM/dd").parse("2014/10/03");
            Calendar cal = Calendar.getInstance();
            cal.setTime(date0);
            while(cal.getTime().compareTo(date1)<=0){
            cal.add(Calendar.DAY_OF_MONTH,1);
              list0.add(sdf.format(cal.getTime()));
            }

方法2：

 /**
              * 求取月分
              */
                 List<String> list01 = new ArrayList<String>();
                Date begin = sdf.parse("2014/01/01");
                 Date end = sdf.parse("2014/10/03");
                 Calendar cal1 = Calendar.getInstance();
                 cal1.setTime(begin);
                 Calendar cal2 = Calendar.getInstance();
                 cal2.setTime(end);
                  int mouths = cal2.get(Calendar.MONDAY)- cal1.get(Calendar.MONTH);//获取年份
                for (int i = 0; i <= mouths; i++) {
                     cal1.add(Calendar.MONTH,1);
                    list01.add(sdfq.format(cal1.getTime()).trim());
                }

3.求取每一年
方法一：

 //方法一
         date0 = new SimpleDateFormat("yyyy").parse("2010");
         Date date1 = new SimpleDateFormat("yyyy").parse("2014");
         Calendar cal = Calendar.getInstance();
         cal.setTime(date0);
         while(cal.getTime().compareTo(date1)<=0){
         list0.add(sdf.format(cal.getTime()));
         cal.add(Calendar.YEAR,1);

         }

方法二：

 Date begin = sdf.parse("2014");
 //            Date end = sdf.parse("2014");
 //            Calendar cal1 = Calendar.getInstance();
 //            cal1.setTime(begin);
 //            Calendar cal2 = Calendar.getInstance();
 //            cal2.setTime(end);
 //             int mouths = cal2.get(Calendar.YEAR)- cal1.get(Calendar.YEAR);//获取年份
 //           for (int i = 0; i <= mouths; i++) {
 //               if(i!=0){
 //                   cal1.add(Calendar.YEAR,1);
 //               }
 //               list02.add(sdfp.format(cal1.getTime()).trim());
 //           }
