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());

 //           }
