java container (jdk1.5)

java容器(since jdk1.5版)   Version 0.2b, 2006/10/26
==================

各容器介面摘要(功能定義):
  Collection 收藏:    放個別物件,  可重複放,無位置概念,無排序
  Queue 佇列:         放個別物件,  可重複放,頭位置概念,部份排序
  List 清單:          放個別物件,  可重複放,任意位置  ,無排序
  Set 集合:           放個別物件,不可重複放,無位置概念,無排序
  SortedSet 有序集合: 放個別物件,不可重複放,有頭尾概念,有排序
  Map 映射:           放成對物件,不可重複放,無位置概念,無排序
  SortedMap 有序映射: 放成對物件,不可重複放,有頭尾概念,有排序

各容器類別摘要(實作各介面的實體類別):
  Collection:   Vector,Stack,ArrayList,ArrayBlockingQueue,
  LinkedList,PriorityQueue,HashSet,TreeSet
  Queue: ArrayBlockingQueue,LinkedList,PriorityQueue
  List:  Vector,Stack,ArrayList,LinkedList
  Set:  HashSet,TreeSet
  SortedSet: TreeSet
  Map:  HashMap,TreeMap,HashTable,Properties
  SortedMap: TreeMap
  --
  Vector 向量,Stack 堆疊,ArrayList 陣列清單,LinkedList 鏈結清單,
  ArrayBlockingQueue 陣列等候佇列,PriorityQueue 順位佇列,
  HashSet 雜湊集合,TreeSet 樹狀集合,
  HashMap 雜湊映射,TreeMap 樹狀映射,
  HashTable 雜湊表,Properties 屬性表

容器演算法:
  Collections.binarySearch/min/max/indexOfSublist/lastIndexOfSublist,
 fill/copy/swap/shuffle/sort/reverse/rotate,
 list/nCopies/enumeration/reverseOrder,
 singleton/singletonList/singletonMap,
 synchronizedCollection/synchronizedSet/synchronizedList,
 synchronizedMap/synchronizedSortedSet/synchronizedSortedMap,
 unmodifiableCollection/unmodifiableSet/unmodifiableList,
 unmodifiableMap/unmodifiableSortedSet/unmodifiableSortedMap,

  Arrays.asList/binarySearch/equals/fill/sort,

容器一般性功能須求:
 新增容器,刪除容器,查詢容器元素個數,列舉容器元素,
 新增元素,刪除元素,修改元素,查詢元素,擷取元素
