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像人员记录一样的ArrayList。我只能做到这一点至今：

---

CODE

---

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); 
} 
}

本网站中的一员告诉我做到以下几点，我真的不得到如何获得关于这样做：

你做

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

，然后你可以反复

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

myList.add(newPerson); 

，你可以通过做

int personNumber = 0; 

Person retrievedPerson = myList.get(personNumber); 

甚至

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

任何帮助完成一个简单的程序利用上述点提到的特定stackoverflow member（即。卡尔Smotricz答案）将不胜感激。

非常感谢
