Write a program to store a bunch of triangles and squares in an arraylist, use object serialization to write the arraylist to a file

And the code below has some errors; need help with it.

public static void main(String[] args) throws IOException, ClassNotFoundException { ArrayList list = new ArrayList<>(); list.add(new Rectangle(2, 3)); list.add(new Square(5)); list.add(new Rectangle(1, 4)); list.add(new Square(1)); list.add(new Rectangle(7, 1)); list.add(new Rectangle(5, 6)); list.add(new Square(9)); ObjectOutputStream oos = new ObjectOutputStream(new FileOutputStream("rectangleandsquares.txt")); oos.writeObject(list);

ObjectInputStream ois = new ObjectInputStream(new FileInputStream("rectangleandsquares.txt")); System.out.println(ois.readObject());

ois.close(); oos.close(); }

}

errors:
