How to get Last latest value from recyclerview : I am making Garage Application just like Calculator..Taking 2 values from Edittext and print in third Edittext.and then it will store all values in recyclerview.**Now issue is I am trying to get the latest Total Gross value ie last row Total Value** I had done all possibly Solution still I am not getting.

Here is my code in Custom Adapter:
  
    @Override
    public void onBindViewHolder(MyViewHolder holder, int position) {
        Employee employee = bank_details.get(position);


        holder.total.setText(employee.getTotal());
        holder.accept.setText(employee.getAcceptmoney());
        holder.given.setText(employee.getGivemoney());
        holder.note.setText(employee.getNote());
        holder.date.setText(employee.getTime());

        int selectedItem = 0;
        if(selectedItem == position)
            holder.itemView.setSelected(true);


    }

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

    public void setSelectedItem(int last_pos) {
    }


    public class MyViewHolder extends RecyclerView.ViewHolder {
        CardView cv;
        TextView total;
        TextView accept;
        TextView given;
        TextView note;
        TextView date;

        Button edit;
        Button delete;

        public MyViewHolder(View itemView) {
            super(itemView);
            cv= (CardView) itemView.findViewById(R.id.cv);
            total = (TextView) itemView.findViewById(R.id.grossIncome);
            accept = (TextView) itemView.findViewById(R.id.acceptmoney);
            given = (TextView) itemView.findViewById(R.id.givenmoney);
            note = (TextView) itemView.findViewById(R.id.note);
            date= (TextView) itemView.findViewById(R.id.date);


        }
    }
    public Employee getItem(int position) {
        return bank_details.get(position);
    }

Here is the code of recyclerview:

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_recyclerview);

        final RecyclerView rv = (RecyclerView) findViewById(R.id.rv);
        rv.setHasFixedSize(true);

        final ArrayList<Employee> arr = InitializeData();

        final LinearLayoutManager llm = new LinearLayoutManager(this);
        rv.setLayoutManager(llm);
        rv.setHasFixedSize(true);

        cu = new CustomAdapter(arr);
        rv.setAdapter(cu);

        int last_pos = cu.getItemCount() - 1;
        cu.notifyDataSetChanged();
        cu.setSelectedItem(last_pos);
        rv.scrollToPosition(last_pos);
    }

    public ArrayList<Employee> InitializeData() {
        ArrayList<Employee> arr_emp = new ArrayList<>();
        ArrayList<Employee> arr_emp_2 = new ArrayList<>();



        DAL dal = new DAL(this);
        dal.OpenDB();
        arr_emp = dal.AllSelectQryForTabEmpData();
        dal.CloseDB();
        return arr_emp;



    }
    public void setSelectedItem(int position)
    {
        selectedItem = position;
    }

Problem is I want total value and that total value can be used as giving and receiving value ie-**Total+receving Money**,**Total-giving Money**
