Javaチェーンの定義と簡単な例

Javaチェーンの定義と簡単な例
Javaは連鎖表を実現して主に引用伝達に頼って、引用は住所として理解することができて、連鎖表のは遍歴して多く再帰を使って、ここで私は1つの疑問が存在して同じ種類の異なった対象の同じ方法の中で呼び出して再帰を計算しません。
ここで私が書いたのは一方向チェーンです。

package com.example.java;

public class MyLink {

public static void main(String [] args){ 

Link l=new Link(); 
  mytype[] la; 
  mytype dsome=new mytype("  ","dsome",21); 
  mytype shao=new mytype("  ","john",45); 
  mytype hua=new mytype("   ","jam",46); 
  mytype duo=new mytype("   ","duo",1000); 
  mytype wang=new mytype("  ","jack",21); 
  mytype shi=new mytype("  ","bob",3000); 
  mytype yu=new mytype("  ","keven",30); 

l.add(dsome);//       
  l.add(shao); 
  l.add(hua); 
  l.add(wang); 
  l.add(shi); 
  l.add(duo); 
  l.add(yu); 

  System.out.println("    ："+l.length());//     
  la=l.toArray(); 
  for(int i=0;i<la.length;i++){ 
 System.out.println(la[i].getInfo()); 
 } System.out.println("      :"+l.contains(duo)+"
"); 
  System.out.println("     
"); 
  l.remove(duo); 
  la=l.toArray(); 
  for(int i=0;i<la.length;i++){//          
   System.out.println(la[i].getInfo()); 
  }  
System.out.println("

   System.out.println(l.get(i).getInfo()); 
  }  
System.out.println("      :"+l.contains(duo)+"

  l.clean(); 
  System.out.println("           : "+l.length()+"\t      ："+l.isEmpty()); 
}

テストの効果は以下の通りです。
