Method

Stringjoin(CharSequence delimiter, Iterable tokens)
Returns a string containing the tokens joined by delimiters. 
StringBuilder sb = new StringBuilder();
Iterator<?> it = tokens.iterator();
if (it.hasNext()) {
    sb.append(it.next());
    while (it.hasNext()) {
        sb.append(delimiter);
        sb.append(it.next());
return sb.toString();
Stringjoin(CharSequence delimiter, Iterable tokens)
join 
StringBuilder sb = new StringBuilder();
boolean firstTime = true;
for (Object token : tokens) {
    if (firstTime) {
        firstTime = false;
    } else {
        sb.append(delimiter);
    sb.append(token);
return sb.toString();
Stringjoin(CharSequence delimiter, Iterable elements)
join 
if (delimiter == null) {
    delimiter = "";
StringBuilder buffer = new StringBuilder();
Iterator<? extends CharSequence> it = elements.iterator();
while (it.hasNext()) {
    buffer.append(it.next());
    if (it.hasNext()) {
...
Stringjoin(CharSequence separator, Iterable strings)
Concatenates strings, using a separator. 
Iterator<?> i = strings.iterator();
if (!i.hasNext()) {
    return "";
StringBuilder sb = new StringBuilder(i.next().toString());
while (i.hasNext()) {
    sb.append(separator);
    sb.append(i.next().toString());
...
Stringjoin(final CharSequence sep, final Iterable src)
join 
return join(sep, new StringBuffer(), src).toString();
Stringjoin(final Iterable elements, final String separator)
join 
final StringBuilder buf = new StringBuilder();
for (final CharSequence element : elements) {
    buf.append(element).append(separator);
if (buf.length() > 0) {
    buf.setLength(buf.length() - separator.length());
return new String(buf);
...
Stringjoin(final Iterable iterable, final CharSequence separator)
Joins the string representations of an Iterable collection of objects to one continues string while separating the entities with the provided separator. 
Iterator<? extends Object> oIt;
if (iterable == null || (!(oIt = iterable.iterator()).hasNext())) {
    return ""; 
final StringBuilder sb = new StringBuilder(String.valueOf(oIt.next()));
while (oIt.hasNext()) {
    sb.append(separator).append(oIt.next());
return sb.toString();
Stringjoin(final Iterable objects, final CharSequence separator)
Joins the given collection of Objects using the given separator and each Object's normal toString() method. 
StringBuilder result = new StringBuilder();
for (Iterator<? extends Object> iter = objects.iterator(); iter.hasNext();) {
    result.append(iter.next().toString());
    if (iter.hasNext()) {
        result.append(separator);
return result.toString();
...
Stringjoin(final Iterable tokens, final String delimiter)
join 
Iterator<? extends Object> oIter;
if (tokens == null || (!(oIter = tokens.iterator()).hasNext()))
    return "";
StringBuilder oBuilder = new StringBuilder(String.valueOf(oIter.next()));
while (oIter.hasNext()) {
    oBuilder.append(delimiter).append(oIter.next());
return oBuilder.toString();
...
Stringjoin(final Iterable iterable, final String separator)
join 
return join(iterable, separator, separator);
