Storing rows returned back in Memory.Urgent Help please

Question

I have a method is thats all information from the Database and I need to hold this data
in a HashMap of some sort of data structure
Lets suppose this result set returns 5 rows.I need to hold all 5 rows in a datastructure.
The variable f_OrderID is the principal and this should return back all values associated with it.
I cant use HashMap as the key:f_OrderID is always the same,
Key f_orderID
Value :f_EffTs,f_ClrAcct f_MsgSeqNum
Please can anyone help me how to store this in memory,
using the same f_OrderID but with different values?
public void getAcctChgDataFromDB(String orderNo,String indicator){
     if((rs == null) ){
                   logger.equals("No rows returned for Order No " + orderNo);
                   throw new AcctChgException("No rows returned for Order No " + orderNo );
              }else
                             while(rs.next()){
                                  f_OrderID  = rs.getString("FixOrderID");
                                  f_EffTs    = rs.getString("EffTs");
                                  f_ClrAcct  = rs.getString("ClrAcct");
                                  f_MsgSeqNum = rs.getString("FixMsgSeqNum");
         } catch (Exception e) {
               e.printStackTrace();
   

Answer 1

well i fell
List<Map<String,Object>> or
List<CustomDTOBean>could be a specific data structure which you can look for.
where List would have reference to 5 Objects(Row) and each object could be a Map or a CustomDTO.If we consider map it would be like structure something like
key=TABLE_COLUMN_NAME
value=TABLE_COLUMN_VALUE
