Help with JAVA Address Book Demo

[Radu]

Hello!
I'm trying to modify JAVA Address Book Demo from Using Java DB in Desktop Applications so the contacts will be saved in a text file and not using DB? I tried modifying this program but I didn't managed to save contacts in a txt file.

Why not? What did you try? Where did you get stuck?

 Thread salvareFisier=new Thread() {
        public void run(){
            for(int i=0; i<5; i%=5){
                try {
                    Thread.sleep(300000);
                } catch (InterruptedException ex) {
                    JOptionPane.showMessageDialog(null,"Salvarea automata a esuat!","Eroare",JOptionPane.ERROR_MESSAGE);
                }
                FileOutputStream fos2=null;
                try {
                    fos2 = new FileOutputStream(fisier);
                } catch (FileNotFoundException ex) {
                    JOptionPane.showMessageDialog(null,"Salvarea automata a esuat!","Eroare",JOptionPane.ERROR_MESSAGE);
                }
                ObjectOutputStream oos2=null;
                try {
                    oos2 = new ObjectOutputStream(fos2);
                    oos2.writeObject(agenda);
                    oos2.close();
                } catch (IOException ex) {
                    JOptionPane.showMessageDialog(null,"Salvarea automata a esuat!","Eroare",JOptionPane.ERROR_MESSAGE);
                }
            }
        };
    };

...okay, and what was the problem? What does that do? What would you expect it to do?

If you want help, you have to be specific. Post an SSCCE that demonstrates exactly what you're doing and the problem you're having. That doesn't mean post your whole project- boil it down to the bare minimum.

That is the thread that save the DB in the choosen file, once at every 5 minutes.


This is the what the save button action must do:

  private void jMenuItemSaveActionPerformed(java.awt.event.ActionEvent evt) {                                              
// TODO add your handling code here:
        JFileChooser fc=new JFileChooser();
        int rezultat=fc.showSaveDialog(this);
        FileOutputStream fos=null;
        if(rezultat==JFileChooser.APPROVE_OPTION){
            try {
                fos = new FileOutputStream(fc.getSelectedFile());
            } catch (FileNotFoundException ex) {
                JOptionPane.showMessageDialog(this,"Fisier invalid!","Eroare",JOptionPane.ERROR_MESSAGE);
            }
            try {
                ObjectOutputStream oos=new ObjectOutputStream(fos);
                oos.writeObject(agenda);
                oos.close();
                
            } catch (IOException ex) {
                JOptionPane.showMessageDialog(this,"Eroare de scriere!","Eroare",JOptionPane.ERROR_MESSAGE);
            }
        }
    }

I also attached the entire program.
