Question

编辑 - 我发现如果我使用“CircusSong”wav文件进行按钮点击，它就会开始播放。因此，我尝试访问的其他文件必须不兼容。如何确定哪种格式的.wav文件可以使用？

注意：我尝试过的每个音频文件都在我的机器上播放（Ubuntu）。他们只是没有得到IntelliJ的认可。

我有这个声音文件在程序运行时播放（直到我停止线程）。我能够成功地将它添加到我的“src”文件夹中的“Sounds”文件夹中。

注意：我刚刚学习如何使用声音文件。如果我转到IntelliJ中的文件，这就是它的样子：

嗯，我想在程序中多发一个声音，到目前为止我已经尝试了两个没有运气的声音。当我将鼠标悬停在错误上时，我会得到“预期的类或接口”：

以下是这两个文件的用途：

字段声明和声音剪辑方法：

public class SimManager implements SimulationEventListener, LineListener {
    File mainMusicThemeSong = new File("src/Sounds/CircusSong.wav");
    File selectionSound = new File("src/Sounds/SelectionSound.wav");
    public static Clip mainClip;
    public static Clip selectionClip;

public void playSelectionSound() {
        try {
            Line.Info linfo = new Line.Info(Clip.class);
            Line line = AudioSystem.getLine(linfo);
            selectionClip = (Clip) line;
            selectionClip.addLineListener(this);
            AudioInputStream audioIn = AudioSystem.getAudioInputStream(selectionSound);
            selectionClip.open(audioIn);
            selectionClip.start();
        } catch (Exception e) {
            System.out.println("ERROR WHILE PLAYING SOUND CLIP");
        }
    }
    public void playMainThemeSong() {
        try {
            Line.Info linfo = new Line.Info(Clip.class);
            Line line = AudioSystem.getLine(linfo);
            mainClip = (Clip) line;
            mainClip.addLineListener(this);
            AudioInputStream audioIn = AudioSystem.getAudioInputStream(mainMusicThemeSong);
            mainClip.open(audioIn);
            mainClip.start();
        }catch(Exception e) {
            System.out.println("ERROR PLAYING MUSIC CLIP");
        }

    }

然后，同样在该课程中，我确定播放哪种声音。单击“运行”后将播放主题。当选择所有其他按钮时，应该播放另一个声音，但我只显示“NORMAL_SETUP_EVENT”，因此没有太多不必要的代码。

public void simulationEventOccurred(SimulationEvent simulationEvent)  {

if (simulationEvent.getEventType() == SimulationEvent.NORMAL_SETUP_EVENT) {
    playSelectionSound(); // <-- THIS DOESN"T WORK
    colonySim.initializeAntColony(); // INITIALIZE NORMALLY
    antSimGUI.setTime(time);
}
if (simulationEvent.getEventType() == SimulationEvent.RUN_EVENT) {

    isMoving = false;
    thisThread = new Thread() {
        public void run() {

            playMainThemeSong(); //<-- THIS WORKS
            mainClip.loop(-1); //<-- THIS LOOPS UNTIL THREAD STOPS
            newTurn(); // START INCREMENTING THROUGH TURNS
        }
    };
    thisThread.start();
}

那么，我是否只有不兼容的文件？因为我的代码没有看到任何错误，因为主题歌曲文件工作得很好。为什么我的.wav文件格式无法识别？

如何判断哪些.wav文件与Java兼容？
