How to create these two methods

public void set(int index, String value) { // Code to set an element of your string list at specified index // to the provided value. You cannot set an item beyond that last // item in the list. Set will only work on elements greater than // or equal to zero and less than size. Do not add elements to the // list with set. Display an error if an index is out of bounds. } public void remove(int index) { // Code to remove the element at the specified index. All elements // after the index are shifted down to fill the hole. You cannot // remove an item beyond the last item in the list. Remove will only // work on elements greater than or equal to zero and less than size. // Display an error if an index is out of bounds. }
