声音在Java中不起作用

Question

I've been researching sound files in Java for the past couple of days and I thought I finally could try and get some sound running.

I coded a small segment but unfortunately, there is no sound be played after running it.
Is there a bug somewhere that I'm not seeing or does this code not work. Thanks.

import java.applet.Applet;
import java.applet.AudioClip;
import java.net.URL;

public class driver {
    public static void main ( String [] args ) throws Exception {
        URL resourceUrl = new URL("file:;///C:/Users/Jack/Desktop/Pok/pokemon.wav");
        final AudioClip clip = Applet.newAudioClip(resourceUrl);
        clip.loop();
    }
}

Answer 1

Let's start with...

URL resourceUrl = new URL("file:;///C:/Users/Jack/Desktop/Pok/pokemon.wav");

Apart from the fact that there is a ; in the path which doesn't belong, there is a simpler way to generate a URL from a File

URL url = new File("C:/Users/Jack/Desktop/Pok/pokemon.wav").toURI().toURL();

Then move onto this...

final AudioClip clip = Applet.newAudioClip(resourceUrl);

Looking at your code, you program isn't an applet, so you really shouldn't be using Applet based methods.

For better ways, start by taking a look at Sound Tutorial

Which might look something more like...

URL url = new File("C:/Users/Jack/Desktop/Pok/pokemon.wav").toURI().toURL();
AudioInputStream ais = AudioSystem.getAudioInputStream(url));
Clip clip = AudioSystem.getClip();
clip.open(ais);
clip.start();
clip.drain(); // Stop the main thread from exiting

Answer 2

This is the correct method to Open an audio clip:

 public SoundClipTest() { try { URL url = this.getClass().getClassLoader().getResource("pokemon.wav"); AudioInputStream audioIn = AudioSystem.getAudioInputStream(url); Clip clip = AudioSystem.getClip(); clip.open(audioIn); clip.start(); } catch (UnsupportedAudioFileException e) { e.printStackTrace(); } catch (IOException e) { e.printStackTrace(); } catch (LineUnavailableException e) { e.printStackTrace(); } } 

Answer 3

Well I think there's something wrong with your url, but not sure. However you could try this to play a sound:

String mySound = "pokemon.wav";
Media media = new Media(mySound);
MediaPlayer mp = new MediaPlayer(media);
mp.play();

You should have pokemon.wav in the same folder where your java file is.
