Iterating through a LinkedHashMap in reverse order

by

The question requires a LinkedHashMap in reverse order, some answers suggesting using a TreeSet but this will reorder the map based upon the key.

This solution allows the iteration over the original LinkedHashMap not the new ArrayList as has also been proposed:

List<String> reverseOrderedKeys = new ArrayList<String>(linkedHashMap.keySet());
Collections.reverse(reverseOrderedKeys);
for (String key : reverseOrderedKeys) {
    RecordItemElement line = linkedHashMap.get(key);
}
