Method

Stringjoin(List items, char separator)
Creates a backslash escaped string, joining all the items. 
StringBuilder sb = new StringBuilder(items.size() << 3);
boolean first = true;
for (Object o : items) {
    String item = o.toString();
    if (first) {
        first = false;
    } else {
        sb.append(separator);
...
Stringjoin(List items, String delimiter)
Joins a list of items into a delimiter-separated string. 
StringBuilder sb = new StringBuilder();
for (int i = 0; i < items.size(); i++) {
    sb.append(items.get(i).toString());
    if (i < items.size() - 1) {
        sb.append(delimiter);
return sb.toString();
...
Stringjoin(List list)
join 
StringBuilder sb = new StringBuilder();
if (list != null) {
    int size = list.size();
    if (size > 0) {
        sb.append(list.get(0));
    for (int i = 1; i < size; i++) {
        sb.append(COMMA).append(list.get(i));
...
Stringjoin(List list, String delim)
Creates a single string from a List of strings seperated by a delimiter. 
if (list == null || list.size() < 1)
    return null;
StringBuilder buf = new StringBuilder();
Iterator<?> i = list.iterator();
while (i.hasNext()) {
    buf.append(i.next());
    if (i.hasNext())
        buf.append(delim);
...
Stringjoin(List list, String sep)
Assemble a list of items into a single string. 
StringBuffer buf = new StringBuffer();
for (int i = 0; i < list.size(); i++) {
    if (i > 0)
        buf.append(sep);
    buf.append(list.get(i).toString());
return buf.toString();
Stringjoin(List objects, String delimiter)
join 
String result = "";
for (Object object : objects) {
    if (result.length() > 0)
        result += delimiter;
    result += object.toString();
return result;
Stringjoin(List parts)
join 
return join(parts, DEFAULT_DELIM);
Stringjoin(List resultList, String sep)
join 
if (null == resultList) {
    return "";
if (resultList.isEmpty()) {
    return "";
StringBuilder sb = new StringBuilder();
for (int i = 0; i < resultList.size(); i++) {
...
Stringjoin(List strings, String delimiter)
Join string pieces and separate with a delimiter. 
if (strings == null || delimiter == null) {
    return null;
StringBuffer str = new StringBuffer();
int most = strings.size() - 1;
if (strings.size() > 1) {
    Iterator<?> iter = strings.iterator();
    for (int i = 0; i < most; i++) {
...
Listjoin(List list1, List list2)
join 
List<E> joinedList = newList();
if (list1 != null) {
    joinedList.addAll(list1);
if (list2 != null) {
    joinedList.addAll(list2);
return joinedList;
