Append object existing file

I would like to append Serializable objects in a existing file, but apparently it deletes the previous stored objects.

For the parameter File F, I send new File(file's path). Maybe my mistake is from there ?

Thank you for helping.

public static void wrinting(File[] tab, File f) throws Exception{

    ArrayList<ImageClass> obj = imagesArray(tab); 
    ObjectOutputStream oos;
    try {
        oos = new ObjectOutputStream(new BufferedOutputStream(new FileOutputStream(f)));    
        for (ImageClass i : obj) {
           oos.writeObject(i);
        }
        oos.close();    
    } catch (IOException e) {
        e.printStackTrace();
    }

}

Open the FileOutputStream like this instead:

new FileOutputStream(f, true)
