java实现日期拆分的方法

Calendar canlandar1 = Calendar.getInstance();//开始时间
Calendar canlandar2 = Calendar.getInstance();//结束时间
canlandar1.setTime(psd);//2009-6-1
canlandar2.setTime(pfd);//2009-6-5
List<Date> returnList = new ArrayList<Date>();
while(canlandar1.compareTo(canlandar2) < 1){
  returnList.add(canlandar1.getTime());
  canlandar1.add(canlandar1.DATE, 1);//每次循环增加一天
}
