Java网络编程中，如何将TCP客户端改写为支持长尾词查询的智能问答系统？

TCP通信是有连接状态的通信，客户端和服务端必须保持连接才能实现通信。下面是简化后的代码：

javapackage cn.mym.tcp;

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

TCP通信是有连接状态的通信，客户端和服务器必须相连才可以实现通信

package cn.mym.tcp; import java.io.DataInputStream; import java.io.DataOutputStream; import java.io.IOException; import java.io.InputStream; import java.io.OutputStream; import java.net.ServerSocket; import java.net.Socket; import java.util.Scanner; public class TCPClient { /** *

function:点对点通信客户端
