MutableCollectionIt is imperative that the user manually synchronize on the returned collection when iterating over it using the standard JDK iterator or JDK 5 for loop.
MutableCollection collection = myCollection.asSynchronized();
...
synchronized(collection)
{
Iterator i = c.iterator(); // Must be in the synchronized block
while (i.hasNext())
foo(i.next());
}
Failure to follow this advice may result in non-deterministic behavior.
The preferred way of iterating over a synchronized collection is to use the collection.forEach() method which is properly synchronized internally.
MutableCollection collection = myCollection.asSynchronized();
...
collection.forEach(new Procedure()
{
public void value(Object each)
{
...
}
});
The returned collection does not pass the hashCode and equals operations through to the backing collection, but relies on Object's equals and hashCode methods. This is necessary to preserve the contracts of these operations in the case that the backing collection is a set or a list.
The returned collection will be serializable if this collection is serializable.

[1, 2, 3] and [2, 3, 4] is [1].difference in interface MutableSet<T>difference in interface SetIterable<T>difference in interface UnsortedSetIterable<T>public <R extends Set<T>> R differenceInto(SetIterable<? extends T> subtrahendSet, R targetSet)

SetIterablethis and setB (elements which
are in one of the sets, but not in both). For instance, for the sets [1, 2, 3] and [2, 3, 4], the symmetric
difference set is [1, 4] . It is the set difference of the union and the intersection.symmetricDifference in interface MutableSet<T>symmetricDifference in interface SetIterable<T>symmetricDifference in interface UnsortedSetIterable<T>public <R extends Set<T>> R symmetricDifferenceInto(SetIterable<? extends T> set, R targetSet)

SetIterablethis are also members of candidateSuperset.
For example, [1, 2] is a subset of [1, 2, 3], but [1, 4] is not.isSubsetOf in interface SetIterable<T>public boolean isProperSubsetOf(SetIterable<? extends T> candidateSuperset)
SetIterablethis are also members of candidateSuperset and the
two sets are not equal. For example, [1, 2] is a proper subset of [1, 2, 3], but [1, 2, 3] is not.isProperSubsetOf in interface SetIterable<T>public MutableSet<UnsortedSetIterable<T>> powerSet()
