Base class is java's AbstractList. We cant modify that

String previousValue = String.valueOf(_utf8List.get(index));
_utf8List.set(index, element);
return previousValue;
}

@Override
public void add(int index, String element) {
_utf8List.add(index, new Utf8(element));
}

public void add(int index, Utf8 element) {
_utf8List.add(index, element);
}

No. Base class only has methods for String in this case.. (Since we are extending AbstractList).
