急！！！！！我想知道ResultSet换做LIST怎么改啊？？？？？？

 try
        {
            int i=0;
            ii=res.getMetaData().getColumnCount();
            while(res.next())
            {
                i++;
                HSSFRow row2=sheet.createRow((short)i);
                for(int j=0;j<ii;j++)
                {
                    String ss="";
                    if(res.getString(j+1)==null)
                        ss="空  null";
                    else
                        ss=res.getString(j+1);
                    cteateCell(wb,row2,(short)j,ss);
                }
            }
        } catch(SQLException e)
        {
            e.printStackTrace();
        }
        wb.write(os);
      os.flush();
      os.close();
    }我现在需要传的是一个LIST 也是对了一张表的遍历 怎么写？？？？？
