Question

每当我尝试音频片段时，都会收到此错误：

java.net.MalformedURLException: no protocol: /Users/videogames/Documents/workspace/TryApplets/res/adv.wav---------

有什么问题？这是程序的代码。（我使用mac，如果这很重要的话）

package game;

import java.applet.*;
import java.net.*;

public class sound {

    /**
     * @param args
     */
    public static void main(String[] args) {
        try {
        URL url = new URL("/Users/videogames/Documents/workspace/TryApplets/res/adv.wav");
        AudioClip clip = Applet.newAudioClip(url);
        clip.play();
        } catch (MalformedURLException murle) {
        System.out.println(murle);
        }
    }
}

Answer 1

网址必须以http://..或file://..开头。显示的URL不是，它不是有效的URL。

Answer 2

URL类的有效协议是

 http, https, ftp, file, and jar

所以试试

URL url = new URL("file://Users/videogames/Documents/workspace/TryApplets/res/adv.wav");

如有疑问，请阅读API
