Passing Data between fragments in Android using Interface

public class FragmentA extends Fragment 
{
    DataPassListener mCallback;
    
    public interface DataPassListener{
        public void passData(String data);
    }

    @Override
    public void onAttach(Context context) 
    {
        super.onAttach(context);
        // This makes sure that the host activity has implemented the callback interface
        // If not, it throws an exception
        try 
        {
            mCallback = (OnImageClickListener) context;
        }
        catch (ClassCastException e) 
        {
            throw new ClassCastException(context.toString()+ " must implement OnImageClickListener");
        }
    }
    
    public View onCreateView(LayoutInflater inflater, ViewGroup container,Bundle savedInstanceState) 
    {
        // Suppose that when a button clicked second FragmentB will be inflated
        // some data on FragmentA will pass FragmentB
        // Button passDataButton = (Button).........
        
        passDataButton.setOnClickListener(new OnClickListener() {
            @Override
            public void onClick(View v) {
                if (view.getId() == R.id.passDataButton) {
                    mCallback.passData("Text to pass FragmentB");
                }
            }
        });
