标题: 通信的问题
这是我写的网络的代码。我不明白为什么彼此写的内容不能在对边显示
import java.io.*;
import java.net.*;
public class TCPServer1 {
public static void main(String args[]) throws Exception {
  ServerSocket server = new ServerSocket(8888);
  Socket socket = null;
  while (true) {
   socket = server.accept();
   InputStream is = socket.getInputStream();
   OutputStream os = socket.getOutputStream();
   // BufferedReader br = new BufferedReader(new
   // InputStreamReader(is));
   DataInputStream dis = new DataInputStream(is);
   BufferedReader sin = new BufferedReader(new InputStreamReader(
     System.in));//从键盘上输入数据
   DataOutputStream dos = new DataOutputStream(os);
   String line = "hello world";
   String readLine = "sorry Client";
   System.out.println("Server:" + dis.readUTF());
   readLine = sin.readLine();
   while (!readLine.equals("bye")) {
   
    dos.writeUTF(readLine);
    dos.flush();
    System.out.println("Server" + readLine);
    System.out.println("Client" + dis.readUTF());
    readLine = sin.readLine();
   }
  }
}
}
import java.io.*;
import java.net.*;
public class TCPClient1 {
public static void main(String args[]) throws Exception {
  Socket socket = new Socket("127.0.0.1", 8888);
  InputStream is = socket.getInputStream();
  OutputStream os = socket.getOutputStream();
  BufferedReader sin = new BufferedReader(
    new InputStreamReader(System.in));// 从键盘上输入数据
  PrintWriter pw = new PrintWriter(os);
  BufferedReader br = new BufferedReader(new InputStreamReader(is));
  String readLine = sin.readLine();
  while (!readLine.equals("bye")) {
   pw.println(readLine);
   pw.flush();
   System.out.println("Server:" + br.readLine());
   readLine = sin.readLine();
  }
  pw.close();
  br.close();
  socket.close();
}
}还请各位大神帮忙啊

   BufferedReader br = new BufferedReader(new InputStreamReader(is));
   String readLine = sin.readLine();
   while (!readLine.equals("bye")) {
    pw.println(readLine);
    pw.flush();

   pw.close();
   br.close();

你先打开TCPServer1 在打开TCPClient1

public class TCPServer1 {

这是一个循环等待的代码。放在while后面没意义啊
