hi Wendy,
see the my code of converting mp3 convertor
import javazoom.jl.decoder.Bitstream;
import javazoom.jl.decoder.JavaLayerException;
import javazoom.jl.player.advanced.AdvancedPlayer;
import javazoom.jl.player.advanced.PlaybackEvent;
import javazoom.jl.player.advanced.PlaybackListener;

import javax.sound.sampled.*;

public class MP3Converter {

public static void main(String[] args) {
    convertMP3ToWAV("input.mp3", "output.wav");
}

public static void convertMP3ToWAV(String mp3FilePath, String wavFilePath) {
    try {
        AudioInputStream mp3Stream = getMP3Stream(mp3FilePath);
        AudioFormat mp3Format = mp3Stream.getFormat();

        AudioFormat pcmFormat = new AudioFormat(
                AudioFormat.Encoding.PCM_SIGNED,
                mp3Format.getSampleRate(),
                16,
                mp3Format.getChannels(),
                mp3Format.getChannels() * 2,
                mp3Format.getSampleRate(),
                false
        );

        AudioInputStream pcmStream = AudioSystem.getAudioInputStream(pcmFormat, mp3Stream);
        AudioSystem.write(pcmStream, AudioFileFormat.Type.WAVE, new java.io.File(wavFilePath));

        mp3Stream.close();
        pcmStream.close();
    } catch (Exception e) {
        e.printStackTrace();
    }
}

private static AudioInputStream getMP3Stream(String mp3FilePath) throws JavaLayerException {
    FileInputStream fileInputStream = null;
    try {
        fileInputStream = new FileInputStream(mp3FilePath);
        Bitstream bitstream = new Bitstream(fileInputStream);
        int channels = bitstream.readFrame().readStereo() ? 2 : 1;
        fileInputStream.close(); // Close and reopen to reset file pointer

        fileInputStream = new FileInputStream(mp3FilePath);
        return new AudioInputStream(new BufferedInputStream(fileInputStream),
                new AudioFormat(AudioFormat.Encoding.PCM_SIGNED,
                        AudioSystem.NOT_SPECIFIED,
                        16,
                        channels,
                        channels * 2,
                        AudioSystem.NOT_SPECIFIED,
                        false),
                AudioSystem.NOT_SPECIFIED);
    } catch (Exception e) {
        throw new JavaLayerException("Error creating MP3 AudioInputStream", e);
    }
}
