节点(Node): 链表的基本构建块是节点,每个节点包含两(三)部分,即 数据element和 指向下一个节点的指针next(指向上一个节点的指针prev)。 单链表(Singly Linked List): 单链表中每个节点只有一个指针,即指向下一个节点的指针。 双链表(Doubly Linked List): 双链表中每个节点有两个指针,一个指向下一个节点,另...

List 接口在 iterator、add、remove、equals 和 hashCode 方法的协定上加了一些其他约定,超过了 Collection 接口中指定的约定。为方便起见,这里也包括了其他继承方法的声明。List 接口提供了 4 种对列表元素进行定位(索引)访问方法。列表(像 Java 数组一样)是基于 0 的。注意,这些操作可能在和某些实现(例如 ...
TheLinkedHashMapclass is very similar toHashMapin most aspects. However, the linked hash map is based on both hash table and linked list to enhance the functionality of hash map. It maintains a doubly-linked list running through all its entries in addition to an underlying array of default ...
Hash table and linked list implementation of theMapinterface, with predictable iteration order. This implementation differs fromHashMapin that it maintains a doubly-linked list running through all of its entries. This linked list defines the iteration ordering, which is normally the order in which ...
走访Linked List 时考虑进位 给出两个 非空 的链表用来表示两个非负的整数。其中,它们各自的位数是按照 逆序 的方式存储的,并且它们的每个节点只能存储 一位 数字。 如果,我们将这两个数相加起来,则会返回一个新的链表来表示它们的和。 您可以假设除了数字 0 之外,这两个数都不会以 0 开头。

This implementation differs fromHashSetin that it maintains a doubly-linked list running through all of its entries.
