Java中List(ArrayList、LinkedList(可以实现堆栈、队列、链表相关操作)、Vector)和Set(HashSet、LinkedHashSet、TreeSet)的区别 Collection |--List:元素是有序(这里指的有序是,元素存取对应的位置不变,如某元素插入是在下标3的位置,则在不变动的情况下,该元素一直在该位置)的,元素可以重复。因为该集合体系有索引。
}publicbooleancontains(String name){//判断元素是否存在returnthis.root.search(name) ;//调用Node类中的查找方法}publicvoiddeleteNode(String data){//删除节点if(this.contains(data)){//判断节点是否存在//一定要判断此元素现在是不是根元素相等的if(this.root.data.equals(data)){//内容是根节点this.root...
* |---Vector:作为List接口的古老实现类;线程安全的,效率低;底层使用Object[] elementData存储 * * * 2. ArrayList的源码分析: * 2.1 jdk 7情况下 * ArrayList list = new ArrayList();//底层创建了长度是10的Object[]数组elementData * list.add(123);//elementData[0] = new Integer(123); * ... ...
数据结构与算法--链表(Linked list) “数据结构与算法”不管是在Java还是在任何语言中都是核心基础知识,就像是盖楼的地基一样,它被广泛的应用于架构的最底层,对于这部分知识的掌握程度能够决定读者以后的高度。 出于这个初衷开更本系列文章,希望能对读者有所帮助。 读者的收获 1、了解链表的底层结构 2、常用的链表...
java LinkedHashMap顺序转list java linkedhashmap遍历 在Java软件开发工作中,最常用到的两个集合就是List和Map了,虽然在面试的时候你经常问道ArrayList和LinkedList的区别,HashMap和Hashtable的区别,如果想面试成功你也必须说出来一两点,但是我还真没有用过LinkedList和Hashtable(可能真的是我工作任务的限制吧)。但是...
从subList()中修改ArrayList不会抛出UnsupportedOperationException--以下操作很好:
(add,containsandremove), assuming the hash function disperses elements properly among the buckets. Performance is likely to be just slightly below that ofHashMap, due to the added expense of maintaining the linked list, with one exception: Iteration over the collection-views of aLinkedHashMap...
