public class LinkedList extends AbstractSequentialList implements List, Deque, Cloneable, java.io.Serializable { private transient Entry header = new Entry(null, null, null); ............. 这个是底层源码

你先建立一个属性int sum=0;直接在node构造器sum+=1;

java 泛型不支持int 必须进行包装转成Integer //你们老师那个能运行?public class LinkedPriorityList { Node head; Node last; public void addNode(E date) { if(head==null){ head=new Node(date); last=head; }else { last.next=new Node(d...

//单链表类 package dataStructure.linearList; import dataStructure.linearList.Node; //导入单链表结点类 import java.util.Iterator; //导入迭代器接口 public class SinglyLinkedList extends AbstractList implements LList //单链表类,...

应该见过链条吧,一环扣一环, 但是总的有头有尾, 定义的head就是头 head = new node(null); 这里的意思就是head没有父节点了, 今后如果要判断一个节点是不是头节点,就判断他的父节点是不是为空, 为空就是父节点, 如果有父节点就证明他处于中间位...

与实现ArrayList的名字一样,为SimpleLinkedList。源码地址,欢迎star,fork 构建一个双向链表 构建的代码如下: ? 1 2 3 4 5 6 7 8 9 10 private static class Node{ E item; Node next; Node prev; public Node(E item, Node next, Node prev) ...

package testTime; import java.util.LinkedList; public class BinaryTree { //根节点 private Node root; //二叉树中节点数量 private int size; //无参构造器 public BinaryTree() { root = new Node(); } //数组构造器 public BinaryTree(in...

public class ZLinkedList {private int size;private Node head;public ZLinkedList(){size = 0;}public void headInsert(Object obj){//if(null== obj) {// do something}Node temp = new Node(obj);if(size ==0){head = temp;}else{temp.setN...

这是LinkedList实现方式 import java.io.*; public class List { /*用变量来实现表头*/ private Node Head=null; private Node Tail=null; private Node Pointer=null; private int Length=0; public void deleteAll() /*清空整个链表*/ { Head=...

public class ZLinkedList {private int size;private Node head;public ZLinkedList(){size = 0;}public void headInsert(Object obj){//if(null== obj) {// do something}Node temp = new Node(obj);if(size ==0){head = temp;}else{temp.setN...
