Method

void	addAll(Collection collection, Iterator iterator) Adds all elements in the iteration to the given collection.
void	addAll(Collection collection, Enumeration enumeration) Adds all elements in the enumeration to the given collection.
void	addAll(Collection collection, T... elements) Adds all elements in the array to the given collection.
Collection	collect(Collection inputCollection, Transformer transformer) Returns a new Collection consisting of the elements of inputCollection transformed by the given transformer.
Collection	collect(Iterator inputIterator, Transformer transformer) Transforms all elements from the inputIterator with the given transformer and adds them to the outputCollection.
boolean	containsAny(final Collection coll1, final Collection coll2) Returns `true` iff at least one element is in both collections15.
boolean	exists(Iterable iterable, Predicate predicate) Answers true if a predicate is true for at least one element of a iterable.
void	filter(Iterable iterable, Predicate predicate) Filter the iterable by applying a Predicate to each element.
E	find(Iterable iterable, Predicate predicate) Finds the first element in the given iterable which matches the given predicate.
void	forAllDo(Iterable iterable, Closure closure) Executes the given closure on each element in the iterable.
Object	get(Object object, int index) Returns the `index`-th value in `object`, throwing `IndexOutOfBoundsException` if there is no such element or `IllegalArgumentException` if `object` is not an instance of one of the supported types.
Collection	intersection(final Collection a, final Collection b) Returns a Collection containing the intersection of the given Collection s.
boolean	isEqualCollection(final Collection a, final Collection b) Returns `true` iff the given Collection s contain exactly the same elements with exactly the same cardinalities.
boolean	isSubCollection(final Iterable a, final Iterable b) Returns `true` iff a is a sub-collection of b, that is, iff the cardinality of e in a is less than or equal to the cardinality of e in b, for each element e in a.
Collection	select(Collection inputCollection, Predicate predicate) Selects all elements from input collection which match the given predicate into an output collection.
Collection	subtract(final Collection a, final Iterable b) Returns a new Collection containing `a - b`.
void	transform(Collection collection, Transformer transformer) Transform the collection by applying a Transformer to each element.
Collection	union(final Collection a, final Collection b) Returns a Collection containing the union of the given Collection s.
Collection	unmodifiableCollection(Collection collection) Returns an unmodifiable collection backed by the given collection.
