        System.out.println("Digite o nome do filme para busca: ");
        var busca = leitura.nextLine();

        String chave = "COLOQUE AQUI A SUA CHAVE DO OMDb";  // Substitua pela sua chave
        String endereco = "https://www.omdbapi.com/?t=" + busca.replace(" ", "+") + "&apikey=" + chave;

        HttpClient client = HttpClient.newHttpClient();

        System.out.println(response.body());
    }
