       public ArrayList<Member> mAllSelect() throws ClassNotFoundException, SQLException{

            

             DriverDB db = new DriverDB();

             conn = db.driverDbcon();

      

             ArrayList<Member> alm = new ArrayList<Member>();

             pstmt = conn.prepareStatement("select * from tb_member");

             while(rs.next()){

                    Member m = new Member();

                    m.setM_id(rs.getString("m_id"));

                    m.setM_pw(rs.getString("m_pw"));

                    m.setM_level(rs.getString("m_level"));

                    m.setM_name(rs.getString("m_name"));

                    m.setM_email(rs.getString("m_email")); 

                    System.out.println(m);

                    alm.add(m);

             }

            

             pstmt.close();

             conn.close();

             rs.close();

             return alm;

            

       }

ArrayList를 쓰는이유?

<%

        Mdao dao = new Mdao();

 

       ArrayList<Member> get_alm = dao.mAllSelect();

 

       for(int i=0;i<get_alm.size();i++){

                   

             Member m = get_alm.get(i);
