voidaddAll(Collection collection, Iterable iterable)
add All 
addAll(collection, iterable.iterator());
voidaddAll(Collection collection, Iterator iterator)
Adds all elements in the iteration to the given collection. 
while (iterator.hasNext()) {
    collection.add(iterator.next());
voidaddAll(Collection pCollection, Iterator pIterator)
Adds all elements of the iterator to the collection. 
while (pIterator.hasNext()) {
    pCollection.add(pIterator.next());
voidaddAll(Collection integerCollection, int[] intArray)
Adds an array of integer values to a collection of Integer 
for (int iValue : intArray) {
    integerCollection.add(iValue);
voidaddAll(Collection c, T[] a)
INTERNAL: Adds all elements in the array to the collection. 
for (int i = 0; i < a.length; i++) {
    c.add(a[i]);
voidaddAll(Collection col, T[] arr)
add All 
if (isEmpty(arr)) {

voidaddAll(Collection coll, T... elems)

for (T elem : elems)
    coll.add(elem);
CaddAll(Collection coll1, Collection coll2)

if (coll1 == null)
    return (C) coll2;
if (coll2 == null)
    return (C) coll1;
Collection<T> cSmaller, cBigger;
if (coll1.size() < coll2.size()) {
    cSmaller = coll1;
    cBigger = coll2;
...
booleanaddAll(Collection collection, Collection toAdd)
add All 
int size = toAdd.size();
boolean result = false;
if (size > 0) {
    if (size < 10)
        for (T element : toAdd)
            result |= collection.add(element);
    else
        result = collection.addAll(toAdd);
...
