Problem in Serializing Object[]??

Question

Hi,
I have a JTable and I am tring to write the TableHeader and TableData which are in the form of Object[] and Object[][].
For writing it into file I am using Following method
public int SaveObject(File file, int[] selectedCases, MainFrame ownedFrom, int prevInd) {
  try {
   os = new FileOutputStream(file);
   s = new ObjectOutputStream(os);
   JTablePanel panel = ownedFrom.getMyTabbedPane ().getMyMainPanel(prevInd).getTopRightComponent().getResultPanel();
   JTableModelExtended model=(JTableModelExtended)(((JTableScrollPane) panel.getTablePanels().get(0)).getHeaderTable().getModel());
         System.out.println ("Writing to File");
   s.writeObject("Writing Object To File");
   s.writeObject((Object[])model.getColumnNames());
   s.writeObject((Object[][])model.getData());
//   s.writeObject (ownedFrom.getMyTabbedPane().getMyMainPanel(prevInd).getHostSplitPane());
//   s.writeObject(ownedFrom.getMyTabbedPane().getMyMainPanel(prevInd).getRightSplitPane());
//   s.writeObject(ownedFrom.getMyTabbedPane().getMyMainPanel(prevInd).getLeftSplitPane());
  } catch (FileNotFoundException e) {
   // TODO Auto-generated catch block
   e.printStackTrace();
   return 0;
  }catch (Exception e) {
   // TODO Auto-generated catch block
   e.printStackTrace ();
   return 0;
  }finally{
   try {
    //s.flush();
    //s.close();
    os.close();
   } catch (Exception e) {
    return 0;
  return 1;
}Now for retriving I am using the following snippnet of code
String str = null;
   Object[] col = null;
   Object[][] data = null;
  int ret_obj= save.SaveObject(fileObj,selectedCase,ownedFrom,prevInd);
  System.out.println("Writing to file"+ret_obj);
  File fileObj2 = new File(fileName+".Obj");
  FileInputStream f = null;
  ObjectInput s = null;
  try {
   f = new FileInputStream(fileObj2);
   s = new ObjectInputStream(f);
  } catch ( Exception e ) {
   System.out.println("Unable to open stream as an object stream");
  try {
   str=(String)s.readObject();// This is coming perfectly
   col = (Object[])s.readObject();// This is coming as null
   data = (Object[][])s.readObject();// This is coming as null
  } catch (ClassNotFoundException e) {
   // TODO Auto-generated catch block
   e.printStackTrace();
  } catch (IOException e) {
   // TODO Auto-generated catch block
   e.printStackTrace();
  try {
   f.close();
  } catch (Exception e) {
   // TODO: handle exception
  }I am new to seralizing technique.Please help me .Are I doing anything wrong
Thnx

Answer 1

Where is your read object method ??He's calling it. Look more closely.
If you're saying he needs to implement it, then you're wrong.
Why did you handle the exception which makes your
code messy ? Throw it away.Bad idea. It should be either handled or thrown, and it should also be logged.
Do this something like that;No, don't.
