Java编程/*1、类与对象的基础题：
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);
