Could Somebody Please Explain....

Question

Could somebody please explain what this section of code is doing with the StopTime? There is plenty more code where that came from, but as I can see it, it is being put into a vector in another section of code as endTime, the vector pdmlist, which I think is where or hows its stored in the vector is being set to null? Then pdmlist is using EndTime value? The StopTime is then being set to a string.
StopTime is then set to blank, then the DateDataFormat is being used. The pdmlist comes back into play, then the df (date format) comes back and it gets converted to uppercase and finally outputted using the outStream.write method to the log file that is created (earlier).
So my quest, as per the other mail, why wont the DB query and order by, order it for the output to the log file. What is the vector doing to it to unsort it? How can I order it?
Vector pdmList = null;
this.setCursor( Cursor.WAIT );
if ( radioAllTime.getChecked() )
pdmList = pdmHelper.buildPDMList( ctx, null, null );
else
pdmList = pdmHelper.buildPDMList( ctx, dateBeginTime.getValue(), dateEndTime.getValue() );
          this.setCursor( Cursor.DEFAULT );
//If nothing was found, then display a message,
          //and return.
          if ( pdmList == null )
               MessageBox.show( "No parametric data found. Log file not generated." , this.getText() );
               return;
if ( pdmList.size() == 0 )
               MessageBox.show( "No parametric data found. Log file not generated." , this.getText() );
               return;
          String Temp;
String Board; // Prodid
String StartTime;
String StopTime;
String Part;
String BoardStatus;
String Actual;
String LoLim;
String HiLim;
String MeasStatus;
String PartType;
String PartNumber;
boolean BoardStatusContext = false;
boolean OneMeasureFailed = false;
java.util.Hashtable htFiles = new Hashtable(10,10);
FileWriter outStream = null;
try
for ( int idx = 0; idx < pdmList.size(); idx++ )
                    //Reset the flags
                    BoardStatusContext = false;
                    OneMeasureFailed = false;
Board = ""; StartTime = ""; StopTime = ""; Part = ""; BoardStatus = ""; Actual = "";
LoLim = ""; HiLim = ""; MeasStatus = ""; PartType = ""; PartNumber = "";
com.ms.wfc.data.DateDataFormat df = new com.ms.wfc.data.DateDataFormat( com.ms.wfc.data.DateFormat.CUSTOM,
"dd-MMM-yy hh:mm:ss" );
// get root context
PDMContext context = ((PDM)pdmList.elementAt(idx)).getContext();
//Make the filename
String fileName = context.getProductName();
if ( fileName == null || fileName.length() == 0 )
fileName = "UNKNOWN";
// Eliminate not allowed characters from the file name
fileName = fileName.replace('\\','_');
fileName = fileName.replace('/','_');
fileName = fileName.replace(':','_');
fileName = fileName.replace('*','_');
fileName = fileName.replace('?','_');
fileName = fileName.replace('\"','_');
fileName = fileName.replace('<','_');
fileName = fileName.replace('>','_');
fileName = fileName.replace('|','_');
fileName += ".log";
if ( htFiles.containsKey( fileName ) )
outStream = (FileWriter)htFiles.get( fileName );
else
File theFile = new File( fileName );
statusBar.getPanels()[0].setText( "File: " + theFile.getAbsolutePath() );
/* if ( ! theFile.canWrite() )
statusBar.getPanels()[0].setText( "Failed: " + theFile.getAbsolutePath() );
MessageBox.show( theFile.getAbsolutePath() + " can not be writen!",
this.getText() );
outStream = new FileWriter( theFile.getAbsolutePath(), false );
htFiles.put( fileName, outStream );
// start writing the log file...
outStream.write( "./" );
StartTime = ((String)df.format( null, context.getStartTime() )).toUpperCase();
StopTime = ((String)df.format( null, context.getStopTime() )).toUpperCase();
Board = context.getProductName();
if ( Board.length() == 0 )
Board = "UNKNOWN";
outStream.write( Board + ".obc[" + StartTime + "\r\n\r\n" );
Sorry the mail is so long. I tried books, but vectors were hard to come by? I've searched through the database on this site too, there are plenty of stuff about sorting and vectors but its hard to use somebody elsed situation for my own circumstances as a guide.
Hope somebody could just shed a bit of light.
Thanks in advance.

PS. I will give duke points (when I work out how to add them, but I only have 5....sorry)
