辦事端server端： 

package com.yuan.socket;

import java.io.*;
import java.net.ServerSocket;
import java.net.Socket;

/**

public class TalkServer4Byte {
  
  private ServerSocket server;
  private int port = 5020;

  public TalkServer4Byte() {
    try {
      server = new ServerSocket(port);
    } catch (IOException e) {
    }
  }

  public void talk() {
    System.out.println("監控端口：" + port);
    Socket socket = null;
    while (true) {
      try {
        // 壅塞期待，每吸收到一個要求就創立一個新的銜接實例
        socket = server.accept();
        System.out.println("銜接客戶端地址：" + socket.getRemoteSocketAddress());

        // 裝潢流BufferedReader封裝輸出流（吸收客戶真個流）
        BufferedInputStream bis = new BufferedInputStream(
            socket.getInputStream());

        DataInputStream dis = new DataInputStream(bis);
        byte[] bytes = new byte[1]; // 一次讀取一個byte
        String ret = "";
        while (dis.read(bytes) != -1) {
          ret += bytesToHexString(bytes) + " ";
          if (dis.available() == 0) { //一個要求
            doSomething(ret);
          }
        }

        }
      }
    }

  }

    }
    return stringBuilder.toString();
  }

  public static String BytesHexString(byte[] b) {
    String ret = "";
    for (int i = 0; i < b.length; i++) {
      String hex = Integer.toHexString(b[i] & 0xFF);
      if (hex.length() == 1) {
        hex = '0' + hex;
      }
      ret += hex.toUpperCase();
    }

  }

  public static void main(String[] args) {
    TalkServer4Byte server = new TalkServer4Byte();
    server.talk();
  }
}

客戶端client代碼：

package com.yuan.socket;

import java.io.DataInputStream;
import java.io.DataOutputStream;
import java.io.IOException;
import java.io.InputStream;
import java.net.InetSocketAddress;
import java.net.Socket;
import java.net.SocketAddress;

/**

public class TalkClient4Byte {
  
  private Socket socket;
  private SocketAddress address;

  public TalkClient4Byte() {
    try {
      socket = new Socket();
      address = new InetSocketAddress("127.0.0.1", 5020);
      socket.connect(address, 1000);
    } catch (IOException e) {
      e.printStackTrace();
    }

  }

  public void talk() {

    try {

      //應用DataInputStream封裝輸出流
      InputStream os = new DataInputStream(System.in);
      
      byte [] b = new byte[1];
      DataOutputStream dos = new DataOutputStream(socket.getOutputStream());
      while (-1 != os.read(b)) {
        dos.write(b); // 發送給客戶端
      }
      
      dos.flush();
      dos.close();
    } catch (IOException e) {
      e.printStackTrace();
    } finally {
      try {
        socket.close();
      } catch (IOException e) {

      }
    }
  }

  public static void main(String[] args) {
    TalkClient4Byte client = new TalkClient4Byte();
    client.talk();
  }

}
