问Java-将ConcurrentHashMap添加到JList中的正确方法？

EN

public class Person {



private String firstName;
private String lastName;



@Override
public int hashCode() {
    final int prime = 31;
    int result = 1;
    result = prime * result
            + ((firstName == null) ? 0 : firstName.hashCode());
    result = prime * result
            + ((lastName == null) ? 0 : lastName.hashCode());
    return result;
}



@Override
public boolean equals(Object obj) {
    if (this == obj)
        return true;
    if (obj == null)
        return false;
    if (getClass() != obj.getClass())
        return false;
    Person other = (Person) obj;
    if (firstName == null) {
        if (other.firstName != null)
            return false;
    } else if (!firstName.equals(other.firstName))
        return false;
    if (lastName == null) {
        if (other.lastName != null)
            return false;
    } else if (!lastName.equals(other.lastName))
        return false;
    return true;
}



public Person(String firstName,String lastName){

    this.setFirstName(firstName);
    this.setLastName(lastName);
}



public String getFirstName() {
    return firstName;
}



private void setFirstName(String firstName) {
    this.firstName = firstName;
}



public String getLastName() {
    return lastName;
}



private void setLastName(String lastName) {
    this.lastName = lastName;
}

ConcurrentHashMap<Integer,Person> storage = new ConcurrentHashMap<Integer, Person>();
    storage.put(1, new Person("Sally","Solomon"));
    storage.put(2, new Person("Harry","Solomon"));

    JFrame frame = new JFrame();
    frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
    JButton jButton1 = new JButton("Button");


    Person [] personArr= storage.values().toArray(new Person[0]);
    String [] names = new String[personArr.length];

    System.out.println(personArr.length);

    for(int i=0; i<personArr.length; i++){
        System.out.println(personArr[i].getFirstName());
        names[i] = personArr[i].getFirstName() + " " + personArr[i].getLastName();
    }



    final JList jList1 = new JList(names);
