Uses of Collection in java.util

Subinterfaces of Collection in java.util

interface	List List is a collection which maintains an ordering for its elements.
interface	Set Set is a collection which does not allow duplicate elements.

Classes in java.util that implement Collection

class	AbstractCollection This class provides a skeletal implementation of the Collection interface, to minimize the effort required to implement this interface.
class	AbstractList This class provides a skeletal implementation of the List interface to minimize the effort required to implement this interface backed by a "random access" data store (such as an array).
class	AbstractSet This class provides a skeletal implementation of the Set interface to minimize the effort required to implement this interface.
class	ArrayList Resizable-array implementation of the List interface.
class	HashSet This class implements the Set interface, backed by a hash table (actually a HashMap instance).
class	Stack The Stack class represents a last-in-first-out (LIFO) stack of objects.
class	Vector The Vector class implements a growable array of objects.

Methods in java.util that return Collection

Collection	HashMap.values() Returns a collection view of the values contained in this map.
Collection	AbstractMap.values() Returns a collection view of the values contained in this map.
Collection	Hashtable.values() Returns a Collection view of the values contained in this Hashtable.
Collection	Map.values() Returns all of the current Map values in a Collection.

Methods in java.util with parameters of type Collection

boolean	ArrayList.addAll(Collection c) Appends all of the elements in the specified Collection to the end of this list, in the order that they are returned by the specified Collection's Iterator.
boolean	ArrayList.addAll(int index, Collection c) Inserts all of the elements in the specified Collection into this list, starting at the specified position.
boolean	AbstractSet.removeAll(Collection c) Removes from this set all of its elements that are contained in the specified collection (optional operation).
boolean	Set.addAll(Collection collection) Adds the objects in the specified Collection which do not exist in this Set.
