        }

        model.removeAllElements();

    }

    public static void main(String[] args) {

        gui.setVisible(true);
    }
}

class Contact {
    private String name;
    private String phone;
    private String email;

    public Contact(String name, String phone, String email) {
        this.name = name;
        this.phone = phone;
        this.email = email;
    }

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public String getPhone() {
        return phone;
    }

    public void setPhone(String phone) {
        this.phone = phone;
    }

    public String getEmail() {
        return email;
    }

    public void setEmail(String email) {
        this.email = email;
    }

    @Override
    public String toString() {
        return name + " (" + phone + ", " + email + ")";
    }
}

这个程序使用了Swing GUI库来创建界面和组件。它使用了一个JList来显示通讯录联系人列表，并提供了添加、删除、编辑和搜索联系人的功能。通讯录联系人数据存储在一个ArrayList中，并使用一个自定义的Contact类来表示联系人。
