new DecoderInputStream(mp3Stream)), format, DecoderInputStream.getLength()) DecoderInputStream报错

info SET 密码 = '654321' WHERE 卡号 = '622588xxxxxxxxxxxx';

（2）模拟某个银行卡注销

UPDATE cardinfo SET 状态 = '注销' WHERE 卡号 = '622202xxxxxxxxxxxx';

抱歉，这是我的疏忽导致的错误。在新版本的 JLayer 库中，`DecoderInputStream` 已被弃用，应使用 `Bitstream` 类来替代。

以下是使用 `Bitstream` 类的代码示例：

（3）模拟某个银行卡挂失（提示：修改银行卡的状态信息）

UPDATE cardinfo SETimport java.io.*;
import javax.sound.sampled.*;
import javazoom.jl.decoder.*;

public class MP3toWAVConverter {
    public 状态 = '挂失' WHERE 卡号 = '622202xxxxxxxxxxxx';

（4）查询本周开户的卡号 static void convert(InputStream mp3Stream, String outputFilename) throws IOException, UnsupportedAudioFileException, Exception {
OutputStream out = new FileOutputStream信息

SELECT 卡号, 创建时间 FROM cardinfo WHERE 创建时间 BETWEEN DATE_SUB(NOW(), INTERVAL 7 DAY) AND NOW(outputFilename);
        Bitstream bitstream = new Bitstream(mp3Stream);
        Decoder decoder = new Decoder();
        AudioFormat format = new();

（5）查询本月交易金额最高的卡号

SELECT c.卡号, SUM(t. AudioFormat(44100, 16, 2, true, false);
        javax.sound.sampled.AudioInputStream ais = new javax.sound.sample交易金额) AS '交易总金额' FROM transinfo t
JOIN cardinfo c ON t.卡片ID = c.d.AudioInputStream(new BufferedInputStream(new ByteArrayInputStream(new byte[0])) , format, AudioSystem.NOT_SPECIFIED);
        SampleBuffer sampleBuffer;
        while (true) {
            Header header = bitstream.readFrame();
            if (header == null) {
                break;
            }
            sampleBuffer = (SampleBuffer) decoder.decodeFrame(header, bitstream);
            ais = new javax.sound.sampled.AudioInputStream(new ByteArrayInputStream卡片ID
WHERE t.交易时间 BETWEEN DATE_FORMAT(NOW(), '%Y-%m-01') AND NOW()
GROUP BY c(sampleBuffer.getBuffer()), format, sampleBuffer.getBufferLength());
            AudioSystem.write(ais, AudioFileFormat.Type.WAVE, out);
.卡号
ORDER BY SUM(t.交易金额) DESC
LIMIT 1;

（6）查询挂失帐号的客户信息

SELECT u.用户名, u.手机号, u.邮箱 FROM userinfo u
JOIN cardinfo c ON u.用户ID = c.用户ID
WHERE c.状态 = '挂失';
