        private Node<T> next;

        public Node(T data) {
            this.data = data;
        }
    }

    public void push(T item) {
        Node<T> newNode = new Node<>(item);
        newNode.next = top;
        top = newNode;
        size++;
    }

    public T pop() {
        if (isEmpty()) {
            throw new EmptyStackException();
        }
        T data = top.data;
        top = top.next;
        size--;
        return data;
    }

    public T peek() {
        if (isEmpty()) {
            throw new EmptyStackException();
        }
        return top.data;
    }

    public boolean isEmpty() {
        return top == null;
    }

    public int size() {
        return size;
    }

    public static void main(String[] args) {
        Stack<Integer> stack = new Stack<>();
        stack.push(1);
        stack.push(2);
        stack.push(3);

        System.out.println("Size of the stack: " + stack.size());

        System.out.println("Top element of the stack: " + stack.peek());

        System.out.println("Popping elements from the stack:");
        while (!stack.isEmpty()) {
            System.out.println(stack.pop());
