实体类

public class Person {  private String firstname; private String lastname; private PhoneNumber phone; private PhoneNumber fax;  public Person(String firstname,String lastname){ this.firstname = firstname;  this.lastname = lastname;  } public String getFirstname() {return firstname;}public void setFirstname(String firstname) {this.firstname = firstname;}public String getLastname() {return lastname;}public void setLastname(String lastname) {this.lastname = lastname;}public PhoneNumber getPhone() {return phone;}public void setPhone(PhoneNumber phone) {this.phone = phone;}public PhoneNumber getFax() {return fax;}public void setFax(PhoneNumber fax) {this.fax = fax;} }public class PhoneNumber {private int code;private String number;public PhoneNumber(int code,String number){this.code = code;this.number = number;}public int getCode() {return code;}public void setCode(int code) {this.code = code;}public String getNumber() {return number;}public void setNumber(String number) {this.number = number;}}
