JDK (Java Development Kit) Tutorials

∟HashSet, Vector, HashMap and Collection Classes

∟Collection Implementations in JDK 1.4.1

This section describes implementation classes of collections with various data structures in JDK 1.4.1: TreeSet, HashSet, LinkedHashSet, ArrayList, LinkedList, Vector, Stack, TreeMap, HashMap, IdentityHashMap, WeakHashMap, Hashtable.

JDK (J2SDK) 1.4.1_02 provides the following implementation classes of collections with various data structures:

       Array       Linked List   Binary Tree   Hash Table

Set                              TreeSet       HashSet
Set                                            LinkedHashSet

List   ArrayList   LinkedList
List   Vector 
List   Stack

Map                              TreeMap       HashMap
Map                                            IdentityHashMap
Map                                            WeakHashMap
Map                                            Hashtable
