这篇文章给大家介绍Java中怎么利用双链表互相交换任意两个节点，内容非常详细，感兴趣的小伙伴们可以参考借鉴，希望对大家能有所帮助。
概述：
双向链表也叫双链表，是链表的一种，它的每个数据结点中都有两个指针，分别指向直接后继和直接前驱。所以，从双向链表中的任意一个结点开始，都可以很方便地访问它的前驱结点和后继结点。一般我们都构造双向循环链表。
思路：
确定两个节点的先后顺序
2、next、prev互相交换顺序以及将换向前方的节点与之前的节点对接。（1.prev.next = 2）
3、判断是否相邻
实现代码：
链表类：
public class SLink { public SNode head; public SLink() { this.head = new SNode(); } public boolean interChangeById(int id1,int id2) { SNode s = head; SNode node1 = null,node2 = null; int node1Count,node2Count; node1Count = node2Count = 0; if(id1 == id2) { return true; } while (s.next != null) { s = s.next; node1Count ++ ; if(s.student.stuId == id1) { node1 = s; break; } } s = head; while (s.next != null) { s = s.next; node2Count ++ ; if(s.student.stuId == id2) { node2 = s; break; } } if(node1 != null && node2 != null) { SNode temp = new SNode(); if(node1Count > node2Count) { temp.next = node1.next; temp.prev = node1.prev; node1.next = node2.next; node1.prev = node2.prev; node2.prev.next = node1; if(node1.next.equals(node1)) { node1.next = node2; node2.next = temp.next; node2.prev = node1; }else { node2.next = temp.next; node2.prev = temp.prev; temp.prev.next = node2; } }else { temp.next = node2.next; temp.prev = node2.prev; node2.next = node1.next; node2.prev = node1.prev; node1.prev.next = node2; if(node2.next.equals(node2)) { node2.next = node1; node1.next = temp.next; node1.prev = node2; }else { node1.next = temp.next; node1.prev = temp.prev; temp.prev.next = node1; } } return true; } return false; } public void displayStudent() { SNode s = head; while (s.next != null) { s = s.next; System.out.println(s.student); } }}节点类：
public class SNode { public Student student; public SNode next; public SNode prev; public SNode(Student student, SNode prev,SNode next) { this.student = student; this.next = next; this.prev = prev; } public SNode() { this.student = null; this.next = null; this.prev = null; }}Student类：
public class Student { public int stuId; public String name; public int age; public String className; public Student(int stuId, String name, int age, String className) { this.stuId = stuId; this.name = name; this.age = age; this.className = className; } public int getStuId() { return stuId; } public void setStuId(int stuId) { this.stuId = stuId; } public String getName() { return name; } public void setName(String name) { this.name = name; } public int getAge() { return age; } public void setAge(int age) { this.age = age; } public String getClassName() { return className; } public void setClassName(String className) { this.className = className; } @Override public String toString() { return "Student{" + "stuId=" + stuId + ", name='" + name + '\'' + ", age=" + age + ", className='" + className + '\'' + '}'; }}关于Java中怎么利用双链表互相交换任意两个节点就分享到这里了，希望以上内容可以对大家有一定的帮助，可以学到更多知识。如果觉得文章不错，可以把它分享出去让更多的人看到。
