Question

When I run a query it returns the following results

periodEndingDate | TotalMin | TimesheetId |
-------------------------------------------
2007-08-19       |  38.000  |            1|
2010-09-17       |  26.500  |            2|

So, I have the following way of getting the values, I know the third one is getting it right (The Number one) but how can I cast to the second and first columns ? (Date) and (Float or Double), the TotalMin is an addition of several columns (minutes) of ints divided by 60.

This is what I have

Statement st = conn.createStatement();
ResultSet rs = st.executeQuery("SELECT periodEndingDate, 
              ((minutesMon+minutesTue+minutesWed+minutesThu+"
              +"minutesFri+minutesSat+minutesSun)/60) as TotalMin, 
              TimesheetId FROM timesheet WHERE employeeID='"+empID+"';");

for (; rs.next();) {
                ArrayList tmData = new ArrayList();
                tmData.add((String) rs.getObject(1));

                tmData.add((String) rs.getObject(2));

                                       //for the timesheet id
                tmData.add(((Number) rs.getObject(3)).intValue()); 

                TimeSheetData.add(tmData);
            }

Thank you

You can use rs.getDate() or rs.getTimestamp() for the first column.

You can use rs.getDouble() for the second one.

This is better than using rs.getObject() and then casting it. I’d change your 3rd column to rs.getInt()

Note : rs.getInt() and rs.getDouble() return primitives that get autoboxed when they are added to your list.
