Java 链表的定义与简单实例

package com.example.java;public class MyLink {public static void main(String [] args){ Link l=new Link();   mytype[] la;   mytype dsome=new mytype("韩敏","dsome",21);   mytype shao=new mytype("邵晓","john",45);   mytype hua=new mytype("华晓风","jam",46);   mytype duo=new mytype("余小风","duo",1000);   mytype wang=new mytype("王秋","jack",21);   mytype shi=new mytype("韩寒","bob",3000);   mytype yu=new mytype("于冬","keven",30); l.add(dsome);//测试增加节点   l.add(shao);   l.add(hua);   l.add(wang);   l.add(shi);   l.add(duo);   l.add(yu);   System.out.println("链表长度："+l.length());//链表长度   la=l.toArray();   for(int i=0;i<la.length;i++){  System.out.println(la[i].getInfo());  } System.out.println("是否包含多余:"+l.contains(duo)+"\n");   System.out.println("删除多余后\n");   l.remove(duo);   la=l.toArray();   for(int i=0;i<la.length;i++){//转化为数组之后输出    System.out.println(la[i].getInfo());   }  System.out.println("\n利用索引方法输出全部数据");   for(int i=0;i<l.length();i++){    System.out.println(l.get(i).getInfo());   }  System.out.println("是否包含多余:"+l.contains(duo)+"\n");   l.clean();   System.out.println("执行清空操作后链表长度: "+l.length()+"\t是否为空链表："+l.isEmpty()); }}
