楼主说有些错误 是说不能包括  “2008-05-21” 吧？

Java code

void getDate(String d1,String d2) throws ParseException{
        SimpleDateFormat sd=new SimpleDateFormat("yyyy-MM-dd");
        Calendar c1=Calendar.getInstance();
        Calendar c2=Calendar.getInstance();
        c1.setTime(sd.parse(d1));
        c2.setTime(sd.parse(d2));
        c2.add(Calendar.DAY_OF_YEAR,-1);
        while(c1.before(c2)){
            c1.add(Calendar.DAY_OF_YEAR, 1);
            int day=c1.get(Calendar.DAY_OF_WEEK);
            //if(day!=Calendar.SUNDAY&&day!=Calendar.SATURDAY)  （除去星期六，星期天）
                System.out.println(sd.format(c1.getTime()));

        }
        
    }
