Bag
If the object is already in the Bag.uniqueSet() then increment its
count as reported by Bag.getCount(Object). Otherwise add it to the
Bag.uniqueSet() and report its count as 1.
Since this method always increases the size of the bag,
according to the Collection.add(Object) contract, it
should always return true. Since it sometimes returns
false, this method violates the contract.

Bag
This will also remove the object from the Bag.uniqueSet().
According to the Collection.remove(Object) method,
this method should only remove the first occurrence of the
given object, not all occurrences.
remove in interface Collectionremove in interface Bagremove in class AbstractCollectionDecoratortrue if this call changed the collectionpublic boolean removeAll(Collection coll)
Bagcoll contains n copies of a given object,
the bag will have n fewer copies, assuming the bag
had at least n copies to begin with.
The Collection.removeAll(Collection) method specifies
that cardinality should not be respected; this method should
remove all occurrences of every object contained in the
given collection.
removeAll in interface CollectionremoveAll in interface BagremoveAll in class AbstractCollectionDecoratorcoll - the collection to removetrue if this call changed the collectionpublic boolean retainAll(Collection coll)
Bagcoll contains n copies of a
given object and the bag has m > n copies, then
delete m - n copies from the bag. In addition, if
e is an object in the bag but
!coll.contains(e), then remove e and any
of its copies.
The Collection.retainAll(Collection) method specifies
that cardinality should not be respected; this method should
keep all occurrences of every object contained in the
given collection.

BagnCopies copies of the specified object to the Bag.
If the object is already in the Bag.uniqueSet() then increment its
count as reported by Bag.getCount(Object). Otherwise add it to the
Bag.uniqueSet() and report its count as nCopies.

BagnCopies copies of the specified object from the Bag.
If the number of copies to remove is greater than the actual number of copies in the Bag, no error is thrown.
