将连续字节[]数据发送到java中的DatagramSocket、DatagramPack中

我正在制作一个java桌面应用程序，在这里我从麦克风录制语音，并在局域网中实时发送这些语音数据到另一个计算机系统，反之亦然

我能够通过麦克风录制声音，并将其输出到系统中的扬声器。现在使用UDP数据报套接字也要这样做，但UDPServer不接收数据流（字节[]）

代码如下：VUClient.java

import javax.swing.*;
import java.awt.*;
import java.awt.event.*;
import java.io.*;
import java.net.*;
import javax.sound.sampled.*;

public class VUClient extends JFrame {

    boolean stopaudioCapture = false;
    ByteArrayOutputStream byteOutputStream;
    AudioFormat adFormat;

    AudioInputStream InputStream;
    SourceDataLine sourceLine;
    Graphics g;

    public static void main(String args[]) {
        new VUClient();
    }

    public VUClient() {
        final JButton capture =
                new JButton("Capture");
        final JButton stop =
                new JButton("Stop");
        final JButton play =
                new JButton("Playback");

        capture.setEnabled(true);
        stop.setEnabled(false);
        play.setEnabled(false);

        capture.addActionListener(
                new ActionListener() {
                    public void actionPerformed(
                            ActionEvent e) {

                    }
                });
        getContentPane().add(capture);

        stop.addActionListener(

                    }
                });
        getContentPane().add(stop);

你在这方面有问题（

字节[]接收数据=新字节[10000]

)

使尺寸比这个大。。。 我成功了

字节[]接收数据=新字节[90000]

它工作得很好……

我运行了代码。。。它很好用。。。有什么问题吗？？虽然我更改了端口号R u单击播放按钮？？当我通过麦克风讲话时，应接收语音包。这样行吗？
