java - Adding items in the list without using reference object and setter methods -

in order display data row-wise i.e first row row.i added data resultset list through reference object .ex-

  while (rs.next()) {                            comp_mps ref = new comp_mps();                                ref.setlogtime(rs.getstring(1));                               ref.setbeam_current(rs.getstring(2));                               ref.setbeam_energy(rs.getstring(3));                               ref.setst4_vs6_bag1_rb(rs.getstring(4));                            st_jsp.add(ref);                          } 

where

st_jsp

list<comp_mps> st_jsp=new arraylist<comp_mps>();  

and comp_mps class name. in jsp display data as

{(r.beam_energy)} 

but have large database , have around 200 columns.so won't able create getter , setter methods columns.so other way exists add data in list , display through jsp page in proper format i.e. row-wise , have subtract data in jsp,i'm not able in java. subtraction code in jsp

<fmt:formatnumber value="${(r.st4_vs6_bag8_rb-row.st4_vs6_bag8_rb)}"   maxfractiondigits="2" minintegerdigits="2" pattern="##.##e0" var="mm">      </fmt:formatnumber> ${(mm)}
