java - 音频问题

Question

每次我尝试有人提出的让按下按钮时声音栩栩如生的建议时，它都不起作用。即使我输入了确切的代码，他们也会告诉我。这种情况不仅发生在这个项目上，也发生在其他几个项目上。有人可以告诉我如何(以实际有效的方式)在按下按钮时发出(即)蜂鸣声。如果您想要特定按钮，请尝试使用“清除”按钮。感谢您提供的任何帮助!

编辑代码以在没有 javafx 的情况下工作

clear.addMouseListener(new MouseAdapter() {
            @Override
            public void mousePressed(MouseEvent arg0) {

                 // open the sound file as a Java input stream
                 String fileLocation = "";
                 InputStream in = new FileInputStream(gongFile);

                 // create an audiostream from the inputstream
                 AudioStream audioStream = new AudioStream(in);

                 // play the audio clip with the audioplayer class
                 AudioPlayer.player.start(audioStream);
            }
        });

请注意，如果您想像这样使用它，请将音频文件放在项目的根目录中，并为 String bip 指定文件名。
