Java executeBatch() - Problem in INSERT (Order of records not maintained)

Question

When we make a executeBatch() . And when the use
select * from DUMMY_FILE_S order by ROWID
or
select * from DUMMY_FILE_SThe rows returned are in different order.( that is its not in the order what is inserted actually)
And this happens once in a While.
This is will happen only if we try many times also So please try with many INSERTs
Please find the Java Code and the Insert SQL.

            Connection conn = null;
            //String db_file_name_prefix = "@localhost:1531:xxxx_y14";
               try {
                   Class.forName("oracle.jdbc.OracleDriver").newInstance();
                   // DriverManager.registerDriver(new oracle.jdbc.OracleDriver());
                    catch (ClassNotFoundException e) {
                           e.printStackTrace();
                           //System.out.println("INSIDE class forname :"+ e.getStackTrace());
               }catch(Exception e){
                    e.printStackTrace();
         try{
                conn = DriverManager.getConnection("jdbc:oracle:thin:@localhost:1531:yyyy_xxxx","my_user","password");
             Statement stmt = conn.createStatement();
               BufferedReader in = new BufferedReader(new FileReader(FILENAME));
             String line = in.readLine();
             System.out.println("Line " + line);
              while(line != null) {
             System.out.println("Line 1" + line);
               stmt.addBatch(line);
             line = in.readLine();
             System.out.println("Outside While");
             in.close();
             int iarray[] = stmt.executeBatch();
             System.out.println("Count" + iarray.length);
             catch (Exception e ){
                     System.out.println("Error attempting to store results for batch " + e.getMessage());
                 } finally {
                     try {
                         conn.commit();
                         conn.close();
                     } catch (Exception se) {
                         System.out.println("Error attempting to store results for batch "+ se.getMessage());
}SQL Data sample
INSERT INTO DUMMY_FILE_S (FILE_NO,S_NO) values (44444,'123456789')
INSERT INTO DUMMY_FILE_S (FILE_NO,S_NO) values (44444,'567891234')
INSERT INTO DUMMY_FILE_S (FILE_NO,S_NO) values (44444,'333333333')
INSERT INTO DUMMY_FILE_S (FILE_NO,S_NO) values (44444,'323232323')

Thanks for your prompt reply.
If we even use ORDER BY clause, we still don't get the records in the order what we inserted.
And we see that the problem is in smt.executeBatch(); is not inserting the records the way its inserted
For Example.
if we insert
INSERT INTO MyTable (SERIAL_NUMBER, DESCRIPTION ) VALUES (1,"test1");
INSERT INTO MyTable (SERIAL_NUMBER, DESCRIPTION ) VALUES (2,"test2");
INSERT INTO MyTable (SERIAL_NUMBER, DESCRIPTION ) VALUES (3,"test3");
INSERT INTO MyTable (SERIAL_NUMBER, DESCRIPTION ) VALUES (4,"test4");Note : (Using smt.executeBatch();)
After that when we use
Select * from MyTable ORDER BY ROWIDFor some time we get the result of the query as ( In the order we Insert )
SERIAL_NUMBER, DESCRIPTION
==========================
1,test1
2,test2
3,test3
4,test4And For some time we get the result of the query as ( We don't get the records in the order we Insert )
SERIAL_NUMBER, DESCRIPTION
==========================
1,test1
3,test3
2,test2
4,test4Is there any work around for this?
Thanks in advance
