反转 ArrayList 最简单的方法是什么？

反转这个ArrayList的最简单方法是什么？

ArrayList<Integer> aList = new ArrayList<>();

//Add elements to ArrayList object
aList.add("1");
aList.add("2");
aList.add("3");
aList.add("4");
aList.add("5");

while (aList.listIterator().hasPrevious())
  Log.d("reverse", "" + aList.listIterator().previous());

Collections.reverse(aList);

例子 （参考 http://www.java2s.com/Code/Java/Collections-Data-Structure/ReverseorderofallelementsofJavaArrayList.htm):

ArrayList aList = new ArrayList();
//Add elements to ArrayList object
aList.add("1");
aList.add("2");
aList.add("3");
aList.add("4");
aList.add("5");
Collections.reverse(aList);
System.out.println("After Reverse Order, ArrayList Contains : " + aList);
