Is it possible to set the default value of an integer sharedpreference as an empty field?

Question

I'm using SharedPreferences to save multiple values from multiple Activities and Fragments and reuse them in various others. This works fine so far. I mostly save Integers. Is it possible to set the default value of such a SharedPreference to be empty, so when the value is shown in a TextView, the TextView will be empty? I want this for user convenience, so the user doesn't have to delete the default value in the field, if he wants to change it.

Here is an example of what I mean:

SharedPreferences sharedPref = getSharedPreferences("Datenspeicher", Context.MODE_PRIVATE);

        int Stk_jahr = sharedPref.getInt("sp_stueckzahl", 0);
    
        Stueckzahl.setText(String.valueOf(Stk_jahr));
    

In this example, if no value is saved in sp_stueckzahl, die TextView Stueckzahl will show a 0. I would prefer it to be empty.

Thank you
