英文:
Sound not playing in Eclipse
问题
这是类SoundTest的代码：
package code;
import java.io.File;
import javax.sound.sampled.AudioInputStream;
import javax.sound.sampled.AudioSystem;
import javax.sound.sampled.Clip;
public class SoundTest {
public static void main(String args[]) {
File sound = new File("main//Sounds//open1.wav");
playSound(sound);
}
public static void playSound(File f) {
try {
File file = f;
if (file.exists()) {
AudioInputStream audio = AudioSystem.getAudioInputStream(file);
Clip clip = AudioSystem.getClip();
clip.open(audio);
clip.start();
// clip.close();
} else {
System.out.println("无法找到文件");
}
} catch (Exception e) {
System.out.println("未成功工作！");
}
}
}
当我运行它时，没有错误或异常，它从未显示“无法找到文件”或“未成功工作！”。但是我听不到声音。我是否需要在Eclipse中更改某种设置以使声音可听，还是我做错了什么？我相当确定声音文件位于正确的位置。
英文:
Here is the code for class SoundTest:
package code;
import java.io.File;
import javax.sound.sampled.AudioInputStream;
import javax.sound.sampled.AudioSystem;
import javax.sound.sampled.Clip;
public class SoundTest {
public static void main(String args[])
{
File sound = new File("main//Sounds//open1.wav");
playSound(sound);
}
public static void playSound(File f)
{
try {
File file = f;
if(file.exists())
{
AudioInputStream audio = AudioSystem.getAudioInputStream(file);
Clip clip = AudioSystem.getClip();
clip.open(audio);
clip.start();
//clip.close();
}
else
{
System.out.println("Can't find file");
}
}
catch(Exception e)
{
System.out.println("Didn't work!");
}
}
}
When I run it, there are no errors or exceptions, and it never says "Can't find file" or "Didn't work!". But I don't hear a sound. Do I have to change some sort of setting in Eclipse to make the sound audible, or am I doing something wrong? I'm pretty sure the sound file is located in the right place.

这不是 Eclipse 的问题。文件是由 Java 打开并播放的，但甚至在音频剪辑完成播放之前，程序就被终止了 - 这意味着 Java 程序没有等待剪辑完成播放。
你的方法缺少一行代码，只需要添加这一行代码，就可以得到你想要的结果，见下文：
Thread.sleep(clip.getMicrosecondLength() / 1000);
因此，在添加了这行代码之后，你的代码应该如下所示，然后你就能听到音乐的播放：
AudioInputStream audio = AudioSystem.getAudioInputStream(file);
Clip clip = AudioSystem.getClip();
clip.open(audio);
clip.start();
Thread.sleep(clip.getMicrosecondLength() / 1000);
英文:
That is not eclipse problem. File is being opened and played by java, but even before that audio clip completes playing, the program is getting terminated - Meaning java program is not waiting for the clip to complete playing
Your method is missing one single line of code to give you what you want, see below
Thread.sleep(clip.getMicrosecondLength() / 1000);
So, after adding this line your code should look like this and you will hear your music
AudioInputStream audio = AudioSystem.getAudioInputStream(file);
Clip clip = AudioSystem.getClip();
clip.open(audio);
clip.start();
Thread.sleep(clip.getMicrosecondLength() / 1000);
