'Can we create an anonymous inner class from a concrete class?

There is something surprising in the following code. The ListCell class is not abstract, but we were able to create an anonymous class from it and override its method! How is this possible?

ListCell<TodoItem> listCell = new ListCell<>() {
    @Override
    public void updateIndex(int i) {
        super.updateIndex(i);
    }
};
