当我运行这个程序时，Client 类会提示用户输入一个命令，该命令应该转到 Server 类并打开一个文件并读取该文件的每一行并将字节长度返回给 Client 类以进行显示。

不幸的是，一旦我输入命令，就没有任何反应并且不知道为什么。

TCP客户端类

package TcpClient;

import java.io.BufferedReader;
import java.io.InputStreamReader;
import java.net.Socket;
import java.io.*;

public class TcpClient {
  public static void main(String[] args) {
    String temp;
    String displayBytes;
    try {
      //create input stream
      BufferedReader inFromUser = new BufferedReader(new InputStreamReader(System.in));
      //create client socket, connect to server
      Socket clientSocket = new Socket("localhost",5555);
      //create output stream attached to socket
      DataOutputStream outToServer =
      new DataOutputStream(clientSocket.getOutputStream());

      System.out.print("Command : ");

      //create input stream attached to socket
      BufferedReader inFromServer =
      new BufferedReader(new InputStreamReader(clientSocket.getInputStream())); …
