how to iterate backwards java code example

Example 1: java iterator backwards

ArrayList<...> a = new ArrayList<...>();

// Add elements to list.

// Generate an iterator. Start just after the last element.
ListIterator li = a.listIterator(a.size());

// Iterate in reverse.
while(li.hasPrevious()) {
  System.out.println(li.previous());
}

Example 2: java reverse loop

for (int i = aList.size() - 1; i >= 0; i--) {
        String s = aList.get(i);
    }
