Istream и Ostream с операторами НЕ используют друзей

Хорошо, здесь много ответов, я выложу свой код, и я просто объясню, что я сделал ... это может помочь юниорам вроде меня: D.

1- Цель:

, мы создадим список RecyclerView, который имеет CheckBox и RadioButton, что-то вроде этого:

2- Класс модели

public class ModelClass {
private String time;
private boolean checked;
private boolean free;
private boolean paid;

public TherapistScheduleModel(String time, boolean checked, boolean free, boolean paid) {
    this.time = time;
    this.checked = checked;
    this.free = free;
    this.paid = paid;
}

public boolean isFree() {
    return free;
}

public void setFree(boolean free) {
    this.free = free;
}

public boolean isPaid() {
    return paid;
}

public void setPaid(boolean paid) {
    this.paid = paid;
}

public String getTime() {
    return time;
}

public void setTime(String time) {
    this.time = time;
}

public boolean getChecked() {
    return checked;
}

public void setChecked(boolean checked) {
    this.checked= checked;
}
}

3-My Amazing Adapter

public class MyAdapter extends RecyclerView.Adapter {
private Context context;
private ListAllListeners listAllListeners;
private ArrayList mDataList;

public MyAdapter(Context context, ArrayList mDataList,
                             ListAllListeners listAllListeners) {
    this.mDataList = mDataList;
    this.listAllListeners = listAllListeners;
    this.context = context;
}

@NonNull
@Override
public MyViewHolder onCreateViewHolder(@NonNull ViewGroup parent, int viewType) {
    LayoutInflater inflater = LayoutInflater.from(parent.getContext());
    View view = inflater.inflate(R.layout.single_view, parent, false);
    return new MyViewHolder(view);
}

@Override
public int getItemCount() {
    if (mDataList != null)
        return mDataList.size();
    else
        return 0;
}

@Override
public void onBindViewHolder(@NonNull final MyViewHolder holder, final int position) {
     //important to:
    //setOnCheckedChangeListener to 'null'
    holder.checkBoxTime.setOnCheckedChangeListener(null);
    holder.freeRB.setOnCheckedChangeListener(null);
    holder.paidRB.setOnCheckedChangeListener(null);

    //Check Box
            holder.checkBoxTime.setText(mDataList.get(holder.getAdapterPosition()).getTime());
    //here we check if the item is checked or not from the model.
    if(mDataList.get(holder.getAdapterPosition()).getChecked())
        holder.checkBoxTime.setChecked(true);
    else
        holder.checkBoxTime.setChecked(false);

    holder.checkBoxTime.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {
        @Override
        public void onCheckedChanged(CompoundButton compoundButton, boolean b) {
            if (b) {
                mDataList.get(holder.getAdapterPosition()).setChecked(true);
                listAllListeners.onItemCheck(holder.checkBoxTime.getText().toString(), holder.getAdapterPosition());
            }
            else {
                mDataList.get(holder.getAdapterPosition()).setChecked(false);
                listAllListeners.onItemUncheck(holder.checkBoxTime.getText().toString(), holder.getAdapterPosition());
            }
        }
    });

    //Radio Buttons

    if(mDataList.get(holder.getAdapterPosition()).isFree())
        holder.freeRB.setChecked(true);
    else
        holder.freeRB.setChecked(false);
    holder.freeRB.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {
        @Override
        public void onCheckedChanged(CompoundButton compoundButton, boolean b) {
            if (b) {
                mDataList.get(holder.getAdapterPosition()).setFree(true);
                listAllListeners.onFreeCheck(holder.freeRB.getText().toString(), holder.getAdapterPosition());
            } else {
                mDataList.get(holder.getAdapterPosition()).setFree(false);
                listAllListeners.onFreeUncheck(holder.freeRB.getText().toString(), holder.getAdapterPosition());
            }
        }
    });

   //***and so on to paidRB***

}//end onBindViewHolder()

public interface ListAllListeners {
//here is a list of clicked listeners to use them as you want ;).
//you can get a list of checked or unChecked of all 
        void onItemCheck(String checkBoxName, int position);
        void onItemUncheck(String checkBoxName, int position);
        void onFreeCheck(String name, int pos);
        void onFreeUncheck(String name, int pos);
        void onPaidCheck(String name, int pos);
        void onPaidUncheck(String name, int pos);
    }

    class MyViewHolder extends RecyclerView.ViewHolder {

        CheckBox checkBoxTime;
        RadioButton freeRB, paidRB;

        MyViewHolder(View itemView) {
            super(itemView);
            checkBoxTime = itemView.findViewById(R.id.timeCheckBox);
            freeRB = itemView.findViewById(R.id.freeRadioBtn);
            paidRB = itemView.findViewById(R.id.paidRadioBtn);
        }
    }//end class MyViewHolder

    }//end class

3- В действии вы получите что-то вроде этого:

myAdapter= new MyAdapter(getActivity().getApplicationContext(), mDataList,
                new MyAdapter.ListAllListeners() {

                    @Override
                    public void onItemCheck(String checkBoxName, int position) {
                        Toast.makeText(getActivity(), "" + checkBoxName + "  " + position, Toast.LENGTH_SHORT).show();
                    }

                    @Override
                    public void onItemUncheck(String checkBoxName, int position) {
                        Toast.makeText(getActivity(), "" + checkBoxName + "  " + position, Toast.LENGTH_SHORT).show();
                    }

                    @Override
                    public void onFreeCheck(String name, int position) {

                        Toast.makeText(getActivity(), "" + name + "  " + position, Toast.LENGTH_SHORT).show();
                    }

                    @Override
                    public void onFreeUncheck(String name, int position) {

                        Toast.makeText(getActivity(), "" + name + "  " + position, Toast.LENGTH_SHORT).show();
                    }

                    @Override
                    public void onPaidCheck(String name, int position) {

                        Toast.makeText(getActivity(), "" + name + "  " + position, Toast.LENGTH_SHORT).show();
                    }

                    @Override
                    public void onPaidUncheck(String name, int position) {

                        Toast.makeText(getActivity(), "" + name + "  " + position, Toast.LENGTH_SHORT).show();
                    }
                });
