String stringifyList(List items)
stringify List

StringBuffer buf = new StringBuffer();
for (String s : items) {
 buf.append(s);
 buf.append(ITEM_SEP);
return (buf.toString());

String stringList(String prefix, String suffix, String separator, Object... objects)
Constructs a list of items in a string form using a prefix and suffix to denote the start and end of the list and a separator string in between the items.

StringBuilder builder = new StringBuilder(prefix);
for (int i = 0; i < objects.length; i++) {
 builder.append(objects[i].toString());
 if (i < objects.length - 1) {
 builder.append(separator);
builder.append(suffix);
...

String stringList2String(final String suffix, final List list)
string List String

if (list == null || list.isEmpty()) {
 return null;
StringBuilder builder = new StringBuilder("");
for (int i = 0; i < list.size(); i++) {
 String value = list.get(i);
 if (value != null && !"".equals(value)) {
 if (i < (list.size() - 1)) {
...

String stringList2String(List list, String separator)
Return list of strings in a single string separated by a separator string.

String ret = "";
for (String s : list) {
 ret += s + separator;
return ret.substring(0, ret.length() - separator.length());

boolean stringListEquals(List left, List right)
Tests if two arrays of strings have the same members irrespective of order.

if (left.size() != right.size()) {
 return false;
if (left.size() == 0) {
 return true;
List<String> copyOfLeft = new ArrayList<String>(left);
List<String> copyOfRight = new ArrayList<String>(right);
