Java try/catch/finally best practices while acquiring/closing resources

Question

While working on a school project, I wrote the following code:

FileOutputStream fos;
ObjectOutputStream oos;
try {
    fos = new FileOutputStream(file);
             


        

Answer 1

How about this guys? No null check, no surprise. Everything is cleaned upon exit.

try {
    final FileOutputStream fos = new FileOutputStream(file);
    try {
        final ObjectOutputStream oos = new ObjectOutputStream(fos);
        try {
            oos.writeObject(shapes);
            oos.flush();
        }
        catch(IOException ioe) {
            // notify user of important exception
        }
        finally {
            oos.close();
        }
    }
    finally {
        fos.close();
    }
}
catch (FileNotFoundException ex) {
    // complain to user
}
catch (IOException ex) {
    // notify user
}
