Uses of Collection in java.util

Subinterfaces of Collection in java.util

interface	List An ordered collection (also known as a sequence).
interface	Set A collection that contains no duplicate elements.
interface	SortedSet A set that further guarantees that its iterator will traverse the set in ascending element order, sorted according to the natural ordering of its elements (see Comparable), or by a Comparator provided at sorted set creation time.

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	AbstractSequentialList This class provides a skeletal implementation of the List interface to minimize the effort required to implement this interface backed by a "sequential access" data store (such as a linked list).
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	LinkedList Linked list implementation of the List interface.
class	Stack The Stack class represents a last-in-first-out (LIFO) stack of objects.
class	TreeSet This class implements the Set interface, backed by a TreeMap instance.
class	Vector The Vector class implements a growable array of objects.
