No.
The method add has the signature
public void add(int index, E element)
where index is the index where the element will be inserted and element is the element to insert.
This method throws the exception IndexOutOfBoundsException if the index is outside the range (index < 0 || index > size()) .
In your case, 4 > 0 , resulting in an exception.
