Method

Stringjoin(Iterator iterator, String s)
join 
StringBuffer stringbuffer = new StringBuffer();
do {
    if (!iterator.hasNext())
        break;
    stringbuffer.append(iterator.next());
    if (iterator.hasNext())
        stringbuffer.append(s);
} while (true);
...
Stringjoin(Iterator iterator, String separator)

Joins the elements of the provided Iterator into a single String containing the provided elements.

if (separator == null) {
    separator = "";
StringBuffer buf = new StringBuffer(256); 
while (iterator.hasNext()) {
    buf.append(iterator.next());
    if (iterator.hasNext()) {
        buf.append(separator);
...
Stringjoin(Iterator iterator, String separator)
join 
if (iterator == null) {
    return null;
if (!iterator.hasNext()) {
    return EMPTY;
Object first = iterator.next();
if (!iterator.hasNext()) {
...
Stringjoin(Iterator objects, String separator)
join 
StringBuffer buf = new StringBuffer();
if (objects.hasNext())
    buf.append(objects.next());
while (objects.hasNext()) {
    buf.append(separator).append(objects.next());
return buf.toString();
Stringjoin(Iterator iterator, String separator)
Joins a iteratable list of objects by the given separator 
if (iterator == null)
    return "";
Object first = iterator.next();
if (!iterator.hasNext())
    return first.toString();
StringBuilder buf = new StringBuilder();
if (first != null) {
    buf.append(first);
...
Stringjoin(Iterator iterator)
join 
StringBuilder builder = new StringBuilder();
while (iterator.hasNext()) {
    builder.append(iterator.next());
    if (iterator.hasNext()) {
        builder.append(", ");
return builder.toString();
...
Stringjoin(String delimiter, Iterator iterator)
join 
if (delimiter == null) {
    delimiter = EMPTY_STRING;
if (!iterator.hasNext()) {
    return EMPTY_STRING;
Object first = iterator.next();
if (!iterator.hasNext()) {
...
Stringjoin(String seperator, Iterator objects)
join 
StringBuffer buf = new StringBuffer();
if (objects.hasNext())
    buf.append(objects.next());
while (objects.hasNext()) {
    buf.append(seperator).append(objects.next());
return buf.toString();
Stringjoin(String seperator, Iterator objects)
join 
StringBuffer sb = new StringBuffer();
if (objects.hasNext())
    sb.append(objects.next());
while (objects.hasNext()) {
    sb.append(seperator).append(objects.next());
return sb.toString();
IteratorjoinIterators(final Iterator... iterators)
join Iterators 
return new Iterator<T>() {
    private int next = 0;
    @Override
    public boolean hasNext() {
        while (next < iterators.length && !iterators[next].hasNext()) {
            next++;
        return next < iterators.length;
