java实现单链表之逆序

下面一段代码准确的介绍了java实现单链表逆序，具体内容就不做详解了，有需要的朋友可以直接拷贝了

package com.ckw.mianshi;

public class SinglelinkedReverse {
 
 class Node{
 int data;
 Node next;
 
 public Node(int data){
 this.data = data;
 } 
 }
 public static void main(String[] args) {
 SinglelinkedReverse slr = new SinglelinkedReverse();
 Node head, tail;
 head = tail = slr.new Node(0);
 for(int i=1; i<10; i++){
 Node p = slr.new Node(i);
 tail.next = p;
 tail = p;
 }
 tail = head;
 while(tail != null){
 System.out.print(tail.data+ );
 tail = tail.next;
 }
 
 head = reverse(head);
 
 System.out.println( );
 while(head != null){
 System.out.print(head.data+ );
 head = head.next;
 }
 }
 private static Node reverse(Node head) {
 Node p1,p2 = null;
 p1 = head;
 
 while(head.next != null){
 p2 = head.next;
 head.next = p2.next;
 p2.next = p1;
 p1 = p2;
 }
 return p2;
 }
}
测试结果：
0 1 2 3 4 5 6 7 8 9
9 8 7 6 5 4 3 2 1 0
