java编程实现单链表的建立

package dataProcess;


import java.util.Scanner;


public class listNode {


/**
* @param args
*/
int data;
listNode next;
public listNode(int datas){
data=datas;
}
public listNode(){}
public listNode creat(){
listNode head=new listNode();
listNode p,s;
p=head;
int x;
boolean cycle=true;
Scanner scan=new Scanner(System.in);
while(cycle){
x=scan.nextInt();
if(x!=0){
s=new listNode(x);
p.next=s;
p=s;
}else cycle=false;
}
head=head.next;
p.next=null;
return head;
}
public void show(listNode head){
listNode p;
p=head;
if(head!=null){
while(p!=null){
System.out.println(p.data);
p=p.next;
}
}
}
public int size(listNode head){
int num=0;
listNode p;
p=head;
while(p!=null){
p=p.next;
num++;
}
return num;
}
public static void main(String[] args) {
// TODO Auto-generated method stub
listNode list=new listNode();
System.out.println("输入链表，0为终止符号");
listNode datalist=list.creat();
System.out.println("打印链表");
list.show(datalist);
System.out.println("链表大小");
System.out.println(list.size(datalist));
}
