电话本java程序代码,java打电话代码

Java编程

/*1、类与对象的基础题：

专注于为中小企业提供网站设计制作、做网站服务,电脑端+手机端+微信端的三站合一,更高效的管理,为中小企业泾县免费做网站提供优质的服务。我们立足成都，凝聚了一批互联网行业人才，有力地推动了成百上千家企业的稳健成长，帮助中小企业通过网站建设实现规模扩充和转变。

1）编程实现：以电话Phone为父类（例：电话有本机号码、打电话、接电话等属性和功能，

当然还有一些其它的特性）， 移动电话Mobilephone和固定电话Fixedphone为两个子类，

并使移动电话实现接口：可移动Moveable。固定电话又有子类：无绳电话Cordlessphone。

设计并定义这四个类（Phone、Mobilephone、Fixedphone、Cordlessphone）和一个接口（Moveable），

明确它们的继承关系，定义子类时给出子类有别于父类的新特性。

*/

class Phone {//定义一个Phone类，其属性为电话号码，方法有打电话和接电话

private String phonenum;

public void callPhone() {}

//无参的构造方法

Phone() {}

//有参的构造方法 以后相似

Phone(String s) {

System.out.println("phonenum = " + s);

}

public void acceptPhone() {

System.out.println("父类方法");

}

}

//定义Mobilephone类，从Phone类继承，实现了Moveable接口

//实现接口要重写其中的全部方法，因为没有给出Moveable接口中的方法，所以就没写,即编译也不会成功，若想看到结果把下面的implements Moveable 注释掉

class MobilePhone extends Phone implements Moveable {

private String cellnum;

public void callPhone() {}//重写父类方法

public void setRing() {} //设置铃声

public void playGame() {} //玩游戏

MobilePhone(String s,String s1) {

super(s);

System.out.println("cellphone = " + s1);

}

}

//定义Fixedphone类，从Phone类继承

class FixedPhone extends Phone {

private String fixednum;

private String s;

FixedPhone() {}

FixedPhone(String s,String s2) {

super(s);

System.out.println("fixednum = " + s2);

}

public void acceptPhone() {

System.out.println("实现了多态性");

}//重写父类方法

public void selectNum() {

}

}

//定义Fixedphone子类

class CordlessPhone extends FixedPhone {

private char num;

public void setPassword() {} //设置密码

CordlessPhone() {

super();

}

CordlessPhone(String s2,String s3,char s4) {

super(s2,s3);

System.out.println("num = " + s4);

}

}

/*2）声明测试类：声明Phone类的数组（含5个元素），

生成五个对象存入数组：其中二个Phone类的对象、一个Mobilephone类的对象、一个Fixedphone类的对象和一个Cordlessphone类的对象，

打印输出每个对象的某个成员变量。将一个父类的引用指向一个子类对象，用这个塑型后的对象来调用某个方法实现多态性。 */

public class Test {

public static void main(String[] args) {

Phone[] p = new Phone[5];

p[0] = new Phone("123");

p[1] = new Phone("456");

p[2] = new MobilePhone("123456","138xxxxxxxxx");

p[3] = new FixedPhone("5861","5861xx");

p[4] = new CordlessPhone("5861xxx","12333",'5');

Phone p1 = new FixedPhone();//将一个父类引用指向子类对象

p1.acceptPhone();//调用方法 实现多态性

求问用java写一个简单的电话簿代码。我是小白，求具体流程。做实验课呢

1 设计功能 如 增加联系人，删除练习人，修改联系人

2 设计界面 用swing画个简单界面。

3 编写功能代码，实现功能。

4 做数据持久化，看是把信息存在数据库，还是存在文件里。
