        list.add("Geeks");
        list.add("10");
        list.add("20");
  
        // Output the list
        System.out.println("AbstractList: " + list);
  
        // Remove the head using remove()
        list.remove(3);
  
        // Print the final list
        System.out.println("Final AbstractList: " + list);
    }
