关于list添加字符串的问题

怎么样用list 添加查询出来的字符串
比如
public class HoldDaoImpl implements IHoldDao {

    //通过用户的名字得到用户所买的股票名字
    public     List getUserHolding(int userid) {
        Connection conn=null;
        PreparedStatement pst=null;
        ResultSet rs=null;
        List list=new ArrayList();
        try{
            conn=ConnectionFactory.getConnection();
            String sql="select name from stock where stock_id=(" +
                    "select stock_id from holding where user_id=?)";
            pst=conn.prepareStatement(sql);
            pst.setInt(1, userid);
            rs=pst.executeQuery();
            while(rs!= null && rs.next()){
              这里怎样用list添加查询出来的name值
                    ？？？？？？
                    ？？？？？？
                    
            }
        }catch(Exception e){
            e.printStackTrace();
        }finally{
            ConnectionFactory.closeResultSet(rs);
            ConnectionFactory.closePreparedStatement(pst);
            ConnectionFactory.closeConnection(conn);
        }

        return list;
    }
