A doubly linked list is a linear data structure, in which the elements are stored in the form of a node. Each node contains three sub-elements. A data part ...
首先,我们需要定义一个双向链表类,包含节点的定义和基本操作方法。 classNode{intdata;Nodeprev;Nodenext;publicNode(intdata){this.data=data;this.prev=null;this.next=null;}}classDoublyLinkedList{Nodehead;publicDoublyLinkedList(){this.head=null;}// 在链表尾部插入节点publicvoidappend(intdata){NodenewNode...
classDoublyLinkedList{Nodehead;Nodetail;publicDoublyLinkedList(){this.head=null;this.tail=null;}// 在链表末尾插入一个节点publicvoidinsert(intdata){NodenewNode=newNode(data);if(head==null){head=newNode;tail=newNode;}else{newNode.prev=tail;tail.next=newNode;tail=newNode;}}// 从链表中删除一...

All of the operations perform as could be expected for a doubly-linked list. Operations that index into the list will traverse the list from the beginning or the end, whichever is closer to the specified index. Note that this implementation is not synchronized.If multiple threads access a link...

LinkedHashMap是HashMap的直接子类,二者唯一的区别是LinkedHashMap在HashMap的基础上,采用双向链表(doubly-linked list)的形式将所有entry连接起来,这样是为保证元素的迭代顺序跟插入顺序相同。上图给出了LinkedHashMap的结构图,主体部分跟HashMap完全一样,多了header指向双向链表的头部(是一个哑元),该双向链表的迭代顺...

LinkedHashMap 是 HashMap 的直接子类,二者唯一的区别是 LinkedHashMap 在 HashMap 的基础上,采用双向链表(doubly-linked list)的形式将所有 entry 连接起来,这样是为保证元素的迭代顺序跟插入顺序相同。该双向链表的迭代顺序就是 entry 的插入顺序。 迭代LinkedHashMap 时不需要像 HashMap 那样遍历整个 table,而只...
