Saving notes

The saving note method accepts two arguments, Note and Context. When a note is not empty, it opens up the SharedPreference editor and saves the data: 

public static void saveNote(Note note, Context context) {
    if (note != null) {
        SharedPreferences sharedPreferences =   
        PreferenceManager.getDefaultSharedPreferences(context);
        SharedPreferences.Editor editor = sharedPreferences.edit();
        editor.putString(note.getId(), note.getNotes());
        editor.apply();
    }
}
