尽管我大量借鉴了@Andrew 的代码，但我确实不得不在这里和那里进行一些调整。以下是我的解决方案的演示，除了一个示例 .wav 文件之外，它是完整的。

// needs to be able to do a wait().
ClipPlayer cp = new ClipPlayer();
// Now run the actual demo
cp.demoSam();
}
private void demoSam() {
/**
* Construct a Sam, capable of playing the "Chook.wav", a 0.1 sec sound.
* NOTE: it's very tricky debugging an incorrectly-located
* resource file, and I'm unable to give a general rule

* directory as the .class file, and there is no surrounding
* package (i.e. we're taking the default package name). If you
* are using a package, you may have to write "myPackage/Chook.wav"

sam = new Sam("Chook.wav"); // or whatever, but it has to be .wav
}
