How to Browse a List With Map and Array List Within the Same List (JAVA)Springboot

Question

I need to go through this List (List) however I cannot, I need to pass the value "options",take the value "option_Id", and go through the option_value and bring the option_value_id and Name

in short, it is a list, with a Map, inside the Map has an Arraylist with another Arraylist and I need to reach the last layer to take this data and store in a MAP

I managed to solve, it was something absurd so somples, follows below the answer in Print

Below the Code of the Complacent Method

 public List<Map> ListarOptions() {
    Map configAlternativa = spiritShopRepository.getConfig(1);
    String url = url_base + "/options";
    Map header = new HashMap();
    header.put("key", util.toStr(configAlternativa.get("SECRET_KEY")));
    List listOptions = restUtil.get(url, header);//passar o Headers


    List lista = new ArrayList();
    lista.add(listOptions.get(0));
    Map option = (Map) lista.get(0);

    List<Map> mapOptions = (List<Map>) option.get("options");

    List<Map> cores = new ArrayList<>();
    List<Map> tamanhos = new ArrayList<>();
    for (Map map : mapOptions) {
        String nome = (String) map.get("name");
        if (nome.equals("Cor") ||
                nome.equals("COR") ||
                nome.equals("cor") ||
                nome.equals("Cores") ||
                nome.equals("CORES") ||
                nome.equals("cores")) {
            cores = (List<Map>) map.get("options_value");
        }
        if (nome.equals("Tamanho") ||
                nome.equals("TAMANHO") ||
                nome.equals("tamanho") ||
                nome.equals("Numeração") ||
                nome.equals("NUMERAÇÃO") ||
                nome.equals("numeração") ||
                nome.equals("Numeracao") ||
                nome.equals("numeracao") ||
                nome.equals("Grade") ||
                nome.equals("GRADE") ||
                nome.equals("grade") ||
                nome.equals("Grades") ||
                nome.equals("GRADES") ||
                nome.equals("grades")) {
            tamanhos = (List<Map>) map.get("options_value");
        }
        System.out.println(nome);
        System.out.println(cores);
        System.out.println(tamanhos);
    }


    System.out.println(lista);


    return listOptions;


}
