List 中删除 元素

public static List<OrderReminderDTO> checkReminderData(List<OrderReminderDTO> data){
        for (Iterator iter = data.iterator(); iter.hasNext();) {
            OrderReminderDTO dto = (OrderReminderDTO) iter.next();
            int totalNum = dto.getTotalNum().intValue();
            // 1000 是显示的标准
            if(totalNum < 1000){
                iter.remove();
            }
        }
        return data;
    }
