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 PhoneNumber implements Serializable

  public PhoneNumber(String areacode, String number)
  {
    this.areacode = areacode;
    this.number = number;
  }


  // Read a phone number from the keyboard
  public static PhoneNumber readNumber()

    FormattedInput in = new FormattedInput();

    // Read in the area code
    System.out.println("\nEnter the area code:");
    String area = Integer.toString(in.intRead());

    // Read in the number
    System.out.println("Enter the local code:");
    String number = Integer.toString(in.intRead());

    System.out.println("Enter the number:");
    number += " " + Integer.toString(in.intRead());

    return new PhoneNumber(area,number);
  }

  public String toString()
  { return areacode + ' ' + number; }

  private String areacode;
  private String number;
}
