我是一名学习 Java 的学生,正在为我的简历做一个独立的项目。我决定做一个 Java 计算器,因为我知道构成它的大部分组件。我不知道该怎么做的一件事是在按钮按下时添加声音。我对 Audiostream 输入的东西有一个模糊的想法。但是我的计算器上的每个按钮都需要独特的声音。现在我的计算器还没有完全完成(听众还没有工作。)我只是想知道将我的 .wav 文件合并到按钮按下的最佳方法是什么。提前致谢。

String soundName = "yourSound.wav";    
AudioInputStream audioInputStream = AudioSystem.getAudioInputStream(new File(soundName).getAbsoluteFile());
Clip clip = AudioSystem.getClip();
clip.open(audioInputStream);
clip.start();

这应该可以帮助您实现您想要的。

是的,您将需要这些进口:-

import java.io.File;
import javax.sound.sampled.AudioInputStream;
import javax.sound.sampled.AudioSystem;
import javax.sound.sampled.Clip;

 public static synchronized void playSound(final String url) {
    new Thread(new Runnable() { // the wrapper thread is unnecessary, unless it blocks on the Clip finishing, see comments
      public void run() {
        try {
          Clip clip = AudioSystem.getClip();
          AudioInputStream inputStream = AudioSystem.getAudioInputStream(Main.class.getResourceAsStream("/path/to/sounds/" + url));
          clip.open(inputStream);
          clip.start(); 
        } catch (Exception e) {
          System.err.println(e.getMessage());
        }
      }
    }).start();
  }

我也是一个学习的学生,刚刚找到了这个解决方案!它对我有用,而且非常简单!

URL soundbyte = new File("yourpath/sound.wav").toURI().toURL();
java.applet.AudioClip clip = java.applet.Applet.newAudioClip(soundbyte);
clip.play();

它知道它适用于 .wav 文件,也可能适用于 .au 文件……似乎不适用于 mp3。
