java实现单链表的整表创建

package com.java.dataStruct;

public class Node<E> {

    E item;
    Node next;
    public Node(){
    }
    public Node(E element){
        this.item = element;
    }
    public Node(E element, Node next){
        this.item = element;
        this.next = next;
    }

}

        Node p;

        Node L = new Node<String>("head");//创建头节点
        L.next = null;

        // 整表创建 - 头插法
        for(int i=; i<=; i++){
            p = new Node<String>();
            p.item = "value"+i;//给节点赋值

            p.next = L.next;
            L.next = p;
        }

        while(L.next != null){
            System.out.println(L.next.item);
            L = L.next;
        }

        int size = ;
        Node p,r;

        Node L = new Node<String>("head");
        r = L;

        // 整表创建 - 尾插法
        for(int i=; i<=; i++){
            p = new Node<String>();
            p.item = "value"+i;

            r.next = p;
            r = p;

            size ++;
        }
        r.next = null;

        while(L.next != null){
            System.out.println(L.item);
            System.out.println(L.next.item);
            L = L.next;
        }
