Hey, @pale jacinth!

I have a problem. In one class I serialize my List of Objects to file. Every object in list have own number like: 1,2,3 etc.

   public static void save() throws FileNotFoundException {
    FileOutputStream fos = new FileOutputStream("src\\tc.ser");
    try {
        ObjectOutputStream oos = new ObjectOutputStream(fos);
        oos.writeObject(players);
        oos.close();
        fos.close();
    }
    catch (FileNotFoundException e) {
        throw new IllegalArgumentException("File not found");
    } catch (IOException e) {
        throw new IllegalArgumentException("Error initializing");
    }
In different class i deserialize file and want to add new Object.

 FileInputStream fi = new FileInputStream("src\\tc.ser");
    try {
        ObjectInputStream oi = new LookAheadObjectInputStream(fi);
        players= (List<Players>) oi.readObject();
        oi.close();
        fi.close();
    } catch (IOException | ClassNotFoundException e) {
        throw new RuntimeException(e);
    }
I have a problem after print list:

Player 1
Player 2
Player 3
When I add new Player i have:

Player 1
Player 2
Player 3
Player 1
Player 2
Why? How to do this to have a access to old class and add new Player 4 etc?

Dude we can't read minds. What is "after print list"?

#

What is "when I add new Players"?

You're touching semi-advanced subjects here, you shouldn't need to be told the obvious about describing your situation

What you just said. How is it done, what is the code and all. Or did you think that code was irrelevant when programming?
