如何实现多个接口Implementing Multiple Interface

4.实现多个接口Implementing Multiple Interface 

接口的优势：马克-to-win：类可以实现多个接口。与之相反，类只能继承一个超类（抽象类或其他类）。 A class can implement multiple interface, but a class can have only one superclass. this is also the difference between abstract class and interface.

例1.4：---

interface HandPhone {

    void talk();

}

interface Computer {

    void surfWeb();

}

class SmartPhoneMark_to_win implements HandPhone, Computer {

    public void surfWeb() {

        System.out.println("只要有wifi， 我就能上网");

    }

    public void talk() {

        System.out.println("马克-to-win： 和传统电话一样， 我能通话");

    }

}

public class Test {

    public static void main(String args[]) {

        SmartPhoneMark_to_win sp = new SmartPhoneMark_to_win();

        sp.surfWeb();

        sp.talk();

    }

}
