Java Utililty Methods List Reverse

List addReverse(List list, List append)
Adds the contents of one list to the other in reverse order.

for (ListIterator i = append.listIterator(append.size()); i.hasPrevious();)
 list.add(i.previous());
return list;

int compareVersions(List list1, List list2)
INTERNAL: Compares two lists of Integers -1, 0, 1 means the first list is less than, equal, greater than the second list.

int n = Math.max(list1.size(), list2.size());
int res = 0;
for (int i = 0; i < n; i++) {
 int l1 = 0;
 if (i < list1.size()) {
 l1 = list1.get(i);
 int l2 = 0;
...

int compareVersions(List version1, List version2)
compare Versions

for (Iterator<Integer> it1 = version1.iterator(), it2 = version2.iterator();;) {
 if (!it1.hasNext()) {
 return it2.hasNext() ? -1 : 0;
 if (!it2.hasNext()) {
 return it1.hasNext() ? 1 : 0;
 Integer num1 = it1.next();
...

int compareVersions(String version1, String version2)
Compares two versions strings (ex.

return compareVersions(version1, version2, 3);

List createReversedList(List inputList)
create Reversed List

List<T> result = new ArrayList<T>(inputList); 
Collections.reverse(result);
return result;

E firstElementOf(List list, int reverseIndexPosition)
Returns the first element of a given List

return list != null && !list.isEmpty() ? list.get(0) : null;

String formatToIp(final List shortList, final boolean reverseOrder)
Formats a List with short values into it's IP-Address representation.

if (shortList == null) {
 return null;
if (reverseOrder) {
 Collections.reverse(shortList);
return shortList.toString().replaceAll(",[ ]*", ".").replaceAll("[\\[\\]]", "");

Iterable getReversedListIterable(final List inList)
get Reversed List Iterable

return new Iterable<T>() {
 @Override
 public Iterator<T> iterator() {
 return getReversedListIterator(inList);
};

Iterable iterateReverse(final List elements)
iterate Reverse

return new Iterable<T>() {
 @Override
 public Iterator<T> iterator() {
 return new Iterator<T>() {
 ListIterator<T> it = elements.listIterator(elements.size());
 @Override
 public boolean hasNext() {
 return it.hasPrevious();
...

String listToArrowSep(List strings, String highlightFirst, String highlightSecond, boolean reversed)
list To Arrow Sep

if (strings.isEmpty())
 return "&6None";
StringBuilder sb = new StringBuilder();
for (String s : strings) {
 if (s.equalsIgnoreCase(highlightFirst)) {
 sb.append("&b").append(s).append("&4").append(reversed ? " <--- " : " ---> ");
 } else if (s.equalsIgnoreCase(highlightSecond)) {
 sb.append("&b").append(s).append("&7").append(reversed ? " <--- " : " ---> ");
