    Question problem in retrieving data via RMS

    hi friends...
    I have Written some codes for adding and retrieving data from RMS:
    public void commandAction(Command command, Displayable displayable) {
            if(command==exit)
            {
                destroyApp(true);
                notifyDestroyed();
            }
            else if(command==start)
            {
                try
                {
                    recordstore=RecordStore.openRecordStore("My RecordStore",true);
                }
                catch(Exception error)
                {
                    alert=new Alert("Error Creating",error.toString(),null,AlertType.WARNING);
                    alert.setTimeout(Alert.FOREVER);
                    display.setCurrent(alert);
                }
                try
                {
                    String outPutData[]={"Mary","Bob","Adam"};
                    for(int x=0;x<3;x++)
                    {
                    byte[] byteOutPutData=outPutData[x].getBytes();
                    recordstore.addRecord(byteOutPutData,0,byteOutPutData.length);
                    }
                }
     
                catch(Exception error)
                {
                        alert=new Alert("Error Waiting",error.toString(),null,AlertType.WARNING);
                        alert.setTimeout(Alert.FOREVER);
                        display.setCurrent(alert);
                }
                try 
                {
                    byte[] byteInputData=new byte[1];
                    int length=0;
                    for(int x=1;x<=recordstore.getNumRecords();x++)
                    {
                        if(recordstore.getRecordSize(x)>byteInputData.length)
                        {
                            byteInputData=new byte[recordstore.getRecordSize(x)];
                        }
                        length=recordstore.getRecord(1,byteInputData,0);
                    }
                    alert = new Alert("Reading", new String(byteInputData, 0,length), null, AlertType.WARNING);
                    alert.setTimeout(Alert.FOREVER);
                    display.setCurrent(alert);
     
     
                }
                catch (Exception error)
                {
                   alert = new Alert("Error Reading", error.toString(),null, AlertType.WARNING);
                   alert.setTimeout(Alert.FOREVER);
                   display.setCurrent(alert); 
                }
                try
                {
                    recordstore.closeRecordStore();
                }
                catch (Exception error) 
                {
                    alert = new Alert("Error Closing", error.toString(),null, AlertType.WARNING);
                    alert.setTimeout(Alert.FOREVER);
                    display.setCurrent(alert);
                }
                if (RecordStore.listRecordStores() != null)
                {
                    try
                    {
                        recordstore.deleteRecordStore("MY RecordStore");
                    }
                    catch (Exception error)
                    {
                        alert = new Alert("Error Removing", error.toString(),null, AlertType.WARNING);
                        alert.setTimeout(Alert.FOREVER);
                        display.setCurrent(alert);
                    }
                }
            }
