      }finally
      {
         if(preparedStatement!=null)

         if(conn!=null)
            conn.close();

      }
   
  
}
}

i got the output like this
2010-05-11->17030
17030
(2010-05-12)-(2010-05-11)->545
545
00:09:05 hh:mm:ss
(2010-05-13)-(2010-05-12)->13452
13452
03:44:12 hh:mm:ss
(2010-05-14)-(2010-05-13)->11572
11572
03:12:52 hh:mm:ss
(2010-05-15)-(2010-05-14)->10556
10556
02:55:56 hh:mm:ss
(2010-05-16)-(2010-05-15)->9036
9036
02:30:36 hh:mm:ss

i need to add all the values

17030+545+13452+11572+10556+9036=>62191(output)

how to change the given code to get the above output

[JosAH]

Skimming through your code I think you want to add all the values of the variable 'result'. Initialize another variable, say, 'grandTotal' to 0 before those loops start and after you have printed out 'result', add it to 'grandTotal'. When those loops have finished that variable contains the sum of it all.

kind regards,

Jos
