Recyclerview Adapt

public class CarAdapter extends RecyclerView.Adapter<CarAdapter.ViewHolder> {

    List<Model>models;
    Context context;

    public CarAdapter(List<Model> models, Context context) {
        this.models = models;
        this.context = context;
    }

    @NonNull    @Override    public ViewHolder onCreateViewHolder(@NonNull ViewGroup parent, int viewType) {

        LayoutInflater layoutInflater = LayoutInflater.from(parent.getContext());
        View view = layoutInflater.inflate(R.layout.design,parent,false);
        return new ViewHolder(view);
    }

    @Override    public void onBindViewHolder(@NonNull ViewHolder holder, int position) {

        holder.name.setText(models.get(position).name);
      

    }

    @Override    public int getItemCount() {
        return models.size();
    }

    public class ViewHolder extends RecyclerView.ViewHolder {

        TextView name;
        

        public ViewHolder(View itemView) {
            super(itemView);

            name = itemView.findViewById(R.id.name);
          

        }
    }

                        models.add(model);

                    }

                    carAdapter = new CarAdapter(models,getApplicationContext());
                    recyclerView.setAdapter(carAdapter);


                } catch (JSONException e) {

        RequestQueue requestQueue= Volley.newRequestQueue(this);
        requestQueue.add(stringRequest);
