bookentry.java

Java Classic Examples是我买的两本书：《JAVA经典实例》和《java入门经典源代码》里边附送光盘里带的源码

import java.io.*;

class BookEntry implements Serializable
{
  public BookEntry(Person person, PhoneNumber number)
  {
    this.person = person;
    this.number = number;
  }

  public Person getPerson()
  { return person; }

  public PhoneNumber getNumber()
  { return number; }

  public String toString()
  {
    return person.toString() +'\n' + number.toString();
  }

  // Read an entry from the keyboard
  public static BookEntry readEntry()
  {
    return new BookEntry(Person.readPerson(), PhoneNumber.readNumber());
  }

  private Person person;
  private PhoneNumber number;
}
