Any particular reason you're not using a List instead of String[]? It'll make these type of operations easier. With an ArrayList, all you need is:

list.add(3, list.remove(list.size() - 1));

Or even shorter if you used a LinkedList:

list.add(3, list.removeLast());

Here's a more complete example based on yours:

LinkedList list = new LinkedList();
list.addAll(Arrays.asList("a", "b", "c", "d", "e"));
list.add(3, list.removeLast());
System.out.println(list); // prints "[a, b, c, e, d]"
