Java链表的链表

Question

我目前正在构建一个程序，它需要我使用链表的链表，我已经创建了我自己的链表，但我不知道如何用链表替换我的对象。我现在的代码是:

import java.io.Serializable;
class ListNode implements Serializable {
private static final long serialVersionUID = 8937086815484947032L;
private Client payload;
private ListNode next;
protected ListNode(Client payload) {
    this.payload = payload;
    this.next = null;
}
protected void setNext(ListNode next) {
    this.next = next;
}
protected ListNode getNext() {
    return next;
}
public String toString() {
    return payload.getClient();
}
}
public class OrderedLinkedList implements Serializable {
private static final long serialVersionUID = 7651599382448755370L;
private ListNode head;
public void add(String givenName, String surname) {
    ListNode newNode = new ListNode(new Client(givenName, surname));
    if (head != null)
        newNode.setNext(head);
    head = newNode;
}
public String toString() {
    ListNode iter = head;
    String collector = "";
    while (iter != null) {
        collector = collector + iter.toString();
        iter = iter.getNext();
    }
    return collector;
}
}

我如何使这个链表，显示另一个链表，然后显示对象客户端。这是对象客户机

的代码

import java.io.Serializable;
public class Client implements Serializable {
private static final long serialVersionUID = 6472982140162477886L;
String givenName;
String surname;
public Client(String givenName, String surname) {
    this.givenName = givenName;
    this.surname = surname;
}
public String getClient() {
    StringBuilder sd = new StringBuilder();
    sd.append("First Name: ").append(givenName).append("tSurname: ").append(surname).append("n");
    return sd.toString();
}
}

我没有使用过泛型，因为我以前从未使用过它们，也不知道如何使用

我只是展开这里的注释:

这就是如何创建一个LinkedLists的LinkedList:

 List<List<Client>> listOfLists= new LinkedList<List<Client>>();

添加新列表:

  listOfLists.add(new LinkedList<Client>());

添加元素:

listOfLists.get(0).add(new Client());

不要忘记导入:

import java.util.List;
import java.util.LinkedList;
