i'm using this code to get the data and to put it in a List :

    Retrofit retrofit= RetrofitInstance.getRetrofitInstance();
    final Api api= retrofit.create(Api.class);
    Call<List<User>> call = api.getUser(sestoken);
    call.enqueue(new Callback<List<User>>() {
        @Override
        public void onResponse(Call<List<User>> call, Response<List<User>> response) {

            if (response.code() != 200){
                Log.e("TAG", "onResponse: something is wrong"+response.code() );



            }
            List<User> users = response.body();



            for (User user : users){

                userList.add(user);
            }

            



           

        }

        @Override
        public void onFailure(Call<List<User>> call, Throwable t) {


        }
    });

and this is the user class package model;

public class User {

private String name;
private String id;


public String getName() { return name; }

public String getId() {
    return id;
}

}

i only need to put the id and name in a hashmap i really didn't know how to do it i could only put the data in a list . appreciate the help

Assuming that user id's are unique, you can create a simple HashMap with user id as the Key and user name as the Value.

Map<Integer, String> userMap = new HashMap<>();

for (User user : users) {
    if (userMap.get(user.getId()) == null)
        userMap.put(user.getId(), user.getName());
}

System.out.println("userMap : " + userMap);
