链表基本结构是节点,节点一般包含数据和指向节点的指针;节点只有指向下一个节点指针的叫单链表(Singly Linked List),有指向上一个节点的指针的叫双链表(Doubly Linked List)。 链表的一些关键特点: 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(
SinglyLinkedList类使用带头节点的方式实现,即head节点,该节点不存储数据,只是标记单链表的开始。 public class SinglyLinkedListDemo { public static void main(String[] args) { Node node1 = new Node(1, "张三"); Node node2 = new Node(3, "李四"); Node node3 = new Node(7, "王五"); Node no...
