这是我今晚要用 Java 做的作业。我的问题是如何实现各种类别:家庭、办公室、ecc...哪个是实现这些类别的最佳解决方案？也许是一个枚举？

这是我的实现:

import java.util.*;

public class Persona {

private String Name;
private String surname;
private String title;
private String mail_addr;
private String company
private String position;
private Phone homePhone;
private Phone officePhone;
private Phone mobilePhone;
private Collection<Phone> otherphonesList

public Persona(String n,String s,String t,String m,String c,String p,Phone hp,Phone of,Phone mp,Collection<Phone> otherphones)
{
    name=n;
    surname=s;
    title=t;
    mail_addr=m;
    company=c;
    position=p;
    homePhone=hp;
    officePhone=of;
    mobilePhone=mp;
    otherphonesList=new ArrayList<Phone>(otherphones);
}

public String getName()
{
    return name;
}

public String getSurname()
{
    return surname;
}

public String getTitle()
{
    return title;
}

public String getMail()
{
    return mail_addr;
}

public String getCompany()
{
    return company;
}

public String getPosition()
{
    return position;
}
}


public class Phone {

private String  phone;
private String description;

public Phone(String phone,String description)
{
    this.phone=phone;
    this.description=description;
}

public String getPhone()
{
    return phone;
}

public String getDescription()
{
    return description;
}


}

Answer 1

您可以编写一个包含您需要的字段的 PhoneBook 类:

public class PhoneBook {
    private Phone homePhone;
    private Phone officePhone;
    private Phone mobilePhone;
    private List<Phone> otherPhones;
    ..getters/setters..
}

public class Phone {
    private String phone;
    private String description;
    ..getters/setters..
}
