making a calculator app and want to update history in second fragment but not able to do

Question

I'm beginner in Android development & I am making a calculator app and want to update history in second fragment but not able to find a perfect solution for updating ListView in second fragment. I tried many solutions but none of them worked properly. I'm using ViewPager to swipe between calculator and history fragments. I tired bundle class but if I use bundle in OnCreat method of first Fragment(CalculatorFragment) with ViewPager it shows me blank screen after starting an App & if I use Bundle class in Equal Button it crashes app. here I am passing id of viewPager as Container of fragments.

what I want to achive. I want to update history in second fragment(HistoryFragment) when ever "=" button is clicked.

here's a sample code of what I have done in my code so far.

MainActivity.java

package com.example.calculatorslide;

import androidx.annotation.RequiresApi;
import androidx.appcompat.app.ActionBar;
import androidx.appcompat.app.AppCompatActivity;
import androidx.viewpager.widget.ViewPager;

import android.annotation.SuppressLint;
import android.os.Build;
import android.os.Bundle;


public class MainActivity extends AppCompatActivity {
    ViewPager viewPager;
    pageAdapter pageAdapter;

    @RequiresApi(api = Build.VERSION_CODES.M)
    @SuppressLint({"SetTextI18n", "UseCompatLoadingForDrawables"})
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        viewPager = findViewById(R.id.viewPager);
        //Get rid of ActionBar
        ActionBar actionBar = getSupportActionBar();
        assert actionBar != null;
        actionBar.hide();
        pageAdapter = new pageAdapter(getSupportFragmentManager(), 2);
        viewPager.setAdapter(pageAdapter);
        getSupportFragmentManager().beginTransaction().add(R.id.ViewPager, 
        new Calculatorfragment()).commit;
    }
}

Example of what I am doing in when Equal button is clicked in CalculatorFragment

public void Equals() {
        String calc = etCalc.getText().toString();
        if (calc.split("\\+").length == 2) {
            String[] calculation = calc.split("\\+");
            String Ans = String.valueOf(Double.parseDouble(calculation[0]) + Double.parseDouble(calculation[1]));
            etCalc.setText(Ans);
            tvCalc.setText(calc);
            HistoryFragment fragment = new HistoryFragment();
            Bundle bundle = new Bundle();
            bundle.putString("key", calc+"="+Ans);
            fragment.setArguments(bundle);
            getFragmentManager().beginTransaction().replace(R.id.ViewPager, fragment).commit;
        }
}

HistoryFragment.java

package com.example.calculatorslide;

import android.os.Bundle;

import androidx.fragment.app.Fragment;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.ListView;
import java.util.ArrayList;


public class HistoryFragment extends Fragment {
    ListView history;
    ArrayList<HistoryList> historyLists;
    String History="";
    View rootView;

    public View onCreat(Bundle savedInstanceState){
       Bundle bumdle = getArguments();
       if (bundle  != null)
       String value = bundle.getString("key");
    }
    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
                             Bundle savedInstanceState) {
        final ArrayList<HistoryList> historyLists = new ArrayList<>();

        if(History.split("=").length==2){
            historyLists.add(new HistoryList(History.split("=")[0],History.split("=")[1]));
        }
        
            historyLists.add(new HistoryList("Example", "Example"));
            historyLists.add(new HistoryList("23+5", "28"));
            HistoryAdapter adapter = new HistoryAdapter(getActivity(), historyLists);
            rootView = inflater.inflate(R.layout.fragment_history, container, false);
            ListView listView = rootView.findViewById(R.id.history);
            listView.setAdapter(adapter);
            return rootView;
    }
}

here in historyLists taking two parameters for calculation and answer to display in ListView.
