Method

voidaddAll(Collection dest, Iterator src)
Adds all the elements from an iterator to a collection. 
while (src.hasNext())
    dest.add(src.next());
voidaddAll(Collection dest, Iterator src)
add All 
if (src != null) {
    while (src.hasNext()) {
        T value = src.next();
        dest.add(value);
CaddAll(final C collection, final Iterator iter)
adds all elements from iter to collection 
while (iter.hasNext()) {
    collection.add(iter.next());
return collection;
voidaddAll(final Collection targetCollection, final Iterator sourceIterator)
Adds all elements that a given Iterator provides to a given Collection of appropriate type 
while (sourceIterator.hasNext()) {
    targetCollection.add(sourceIterator.next());
voidaddAll(Iterator iteratorFrom, Collection collectionTo)
If the given Iterator is not null, iterate over all T elements in it and add them to the given Collection. 
if (iteratorFrom != null) {
    while (iteratorFrom.hasNext()) {
        collectionTo.add(iteratorFrom.next());
UaddAll(Iterator source, U target)

while (source.hasNext()) {
    target.add(source.next());
return target;
ListaddAll(List target, Iterator source)
add All 
if (source == null)
    return target;
for (; source.hasNext(); target.add(source.next()))
    ;
return target;
voidaddAll(Set s, Iterator i)
add All 
while (i != null && i.hasNext()) {
    s.add(i.next());
COLLaddAllFromIterator(COLL dest, Iterator source)
add All From Iterator 
while (source.hasNext()) {
    dest.add(source.next());
return dest;
LinkedListaddAllToList(Iterator i)
