How to calculate grand total in query in SQL developer in oracle.

Break on report
Compute Sum is not working in SQL developer.It works only in SQL plus.
Don't want to use group function also.
Is there any way to run a query in SQL developer and show the total at the end of the results/rows.
Also want to use it in jdbc java the query

For Example , i need to select a table and list all records matching certain criteria and show the sum at the end of the records

```
Select volume, value , *.t1 from table1 t1 where trunc(create_date) = trunc(sysdate)

```

This will display say 50 records..i want to display at the end of all records under column volume and value ,the grand total of these 2 columns.

```
        Volume  value   xxx  yy  zzzz
        25       123.5  aa   bb   cc
        35       10     a    c    b
        50       100    c   nn    xc

       --        --
       110       233.5
