JAVA socket TCP 编程

Question

import java.io.IOException;
import java.io.InputStream;
import java.io.OutputStream;
import java.io.PrintWriter;
import java.net.ServerSocket;
import java.net.Socket;

public class ServerTest {

private ServerSocket ss;

private Socket socket;

PrintWriter out;

private int i = 0;

public ServerTest() {

    try {
        ss = new ServerSocket(7838);

        while (true) {

            System.out.println(0);

            socket = ss.accept();

            ss.setSoTimeout(50000);
            byte[] b = new byte[1024];
            b[0] = (byte) 0x55;
            b[1] = (byte) 0xAA;
            b[2] = (byte) 0x01;
            b[3] = (byte) 0x00;
            b[4] = (byte) 0x00;
            b[5] = (byte) 0x00;
            b[6] = (byte) 0x00;
            b[7] = (byte) 0x00;
            b[8] = (byte) 0x00;
            b[9] = (byte) 0x00;
            b[10] = (byte) 0x00;
            b[11] = (byte) 0x00;
            b[12] = (byte) 0x00;
            b[13] = (byte) 0x00;
            b[14] = (byte) 0x00;
            b[15] = (byte) 0x00;
            b[16] = (byte) 0x00;

            InputStream socketReader = socket.getInputStream();

            OutputStream socketWriter = socket.getOutputStream();

            socketWriter.write(b);
            System.out.println("OK");
            socketWriter.flush();

            i = i + 1;
            out.flush();

        }

    } catch (IOException e) {
        e.printStackTrace();
    }

}

public static void main(String[] args) {

    new ServerTest();

}

}

这是服务器端代码 客户端是个终端机,终端机要给用服务器端发十六进制的包,然后返回十六进制的包
用TCP协议，JAVA socket编写，请教如何实现啊，或者给一些帮助提示
谢谢你们了

朋友，这里有些socket方面的例子，

<>的代码，不错
