Question

        List userProcessedCountCol = new ArrayList();
                  while (iResultSet1.next()) {
                        afRealTimeIssuance afRealTimeIssuance = new afRealTimeIssuance();
                        Integer i = 0;

                        afRealTimeIssuance.setSub_channel(iResultSet1.getString(++i));
                        afRealTimeIssuance.setAgent_names(iResultSet1.getString(++i));
                        afRealTimeIssuance.setFtd(iResultSet1.getDouble(++i));
                        afRealTimeIssuance.setMtd(iResultSet1.getDouble(++i));
                        afRealTimeIssuance.setQtd(iResultSet1.getDouble(++i));

                        userProcessedCountCol.add(afRealTimeIssuance);
}

where afRealTimeIssuance is ActionForm

Using the above snippet I get something like below output

1             A             100
2             B             200
3             C             300
4             D             400

But I want to rearrange the output as

2            B              200
4            D              400
3            C              300
1            A              100

In short I want to rearrange the rows as I want.How to arrange the resultset data based on one particular value.Please guide

Answer 1

The ResultSet cannot be rearranged manually (only with sql) . What you can rearrange is your data structure that you hold your Objects

You can use an ArrayList of your row Objects and insert each row in the position you would like.

Lets say in your example, in the while loop:

userProcessedCountCol.add(index, element);
