手写linkList 先写链结点Node Node包含一个数据域和一个指针域 package com.zxl.ch03; /** * 链结点，相当于车厢 */ public class Node { public long data;//数据域 public Node next;//结点域或者指针域 public Node(long value){ this.data = value; } public void display(){

手写MyStack package com.zxl.ch02; /** * 栈的底层是数组，遵循规则：后入先出 */ public class MyStack { private long[] arr; private int top; public MyStack(){ this.arr = new long[10]; this.top = -1; } public MyStack(int maxsize){

自定义数组 package com.zxl.ch00; public class MyArray { private long[] arr;//数组 private int elements;//指针 public MyArray() { this.arr = new long[50]; } public MyArray(int maxsize) { this.arr = new long[maxsize]; }
