Recall the IntegerList ADT whose interface is reproduced below. (Comments are included to remind you what each method does.) public interface IntegerListinterface public boolean isEmpty: 17 return true iff list has no elements public int size ) public int get (int index)7 return list element at index public void add (int index, int newItem): 17 insert newItem at index public void remove (int index); 1/ delete element at index public void removeAll 0: 1/ reset list to empty state // return number of elements in list 1. Write a static void method called swap with the following heading that interchanges the items currently in positions i and j of the list. Use only the ADT operations above to do this. static void swap (IntegerList list, int i, int j)
