如何执行 ArrayList 实现以存储人员详细信息

Question

我需要实现一个可以保存类似人员记录的 ArrayList。到目前为止我只能这样做：

---

代码

---

import java.util.*;

class ArrayListDemo {

public static void main(String args[]) {

    ArrayList al = new ArrayList();
    System.out.println("Initial size of al: "
            + al.size());

    al.add("C");
    al.add("A");
    al.add("E");
    al.add("B");
    al.add("D");
    al.add("F");
    al.add(1, "A2");
    System.out.println("Size of al after additions: "
            + al.size());

    System.out.println("Contents of al: " + al);

    al.remove("F");
    al.remove(2);
    System.out.println("Size of al after deletions: "
            + al.size());
    System.out.println("Contents of al: " + al);
}
}

该网站的一位成员告诉我执行以下操作，我真的不知道该怎么做：

---

你会的

ArrayList<Person> myList = new ArrayList<Person>();

然后你可以重复

newPerson = new Person("Bruce", "Wayne", 1972, "Gotham City");

myList.add(newPerson);

您可以通过以下方式访问列表中的人员

int personNumber = 0;

Person retrievedPerson = myList.get(personNumber);

甚至

for (Person someone : myList) {
   System.out.println(someone);
}

任何关于利用特定stackoverflow member（即 Carl Smotricz 的回答）提到的上述要点的简单程序的帮助将不胜感激。

非常感谢
