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();
    }
}
