import java.util.List;

public class Du2 {

public static void main(String[] args) {

int date1 = 20111001;
int date2 = 20111101;

List<Date> list = getJulianDate(date1, date2);

for(Date date: list){
System.out.println(date.toLocaleString());
}

}

private static List<Date> getJulianDate(int date1, int date2) {

Calendar cal = Calendar.getInstance();

cal.set(Calendar.YEAR, date1 / 10000);
cal.set(Calendar.MONTH, date1 /100 % 100 - 1);
cal.set(Calendar.DATE, date1 % 100);

final SimpleDateFormat sdf = new SimpleDateFormat("yyyyMMdd");
List<Date> list = new ArrayList<Date>();

while(Integer.parseInt(sdf.format(cal.getTime())) <= date2){
list.add(cal.getTime());
cal.add(Calendar.DATE, 1);
}

return list;
}

}
