尝试音频剪辑

Question

每当我尝试音频剪辑时，我都会收到这样的错误：

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

有什么问题吗？这是该程序的代码。(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

URL必须以类似http://..或file://..之类的内容开头。显示的URL不是，它不是有效的URL。

Answer 2

URL类的有效协议为

 http, https, ftp, file, and jar

所以试一试

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