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());   
//           }
