【Java】已解决：`javax.sound.sampled.UnsupportedAudioFileException`

在Java中处理音频文件时，javax.sound.sampled.UnsupportedAudioFileException是一种常见的异常。...一、分析问题背景 javax.sound.sampled.UnsupportedAudioFileException异常通常在尝试读取或播放音频文件时出现。...Java的javax.sound.sampled包提供了用于处理音频数据的工具，但它并不支持所有的音频格式。当程序尝试处理一个不受支持的文件格式时，就会抛出此异常。...import javax.sound.sampled.*; public class AudioPlayer { public void playAudio(String filePath)...通过遵循以上建议，您可以有效避免javax.sound.sampled.UnsupportedAudioFileException，确保音频处理程序的健壮性和用户体验的流畅性。
