Subinterfaces of Collection in java.util

Modifier and Type	Interface and Description
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

Modifier and Type	Class and Description
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	LinkedHashSet Hash table and linked list implementation of the Set interface, with predictable iteration order.
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	Vector The Vector class implements a growable array of objects.
