Socket中的面向连接

服务器：

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.HashMap;
import java.util.Map;

public class Server {
 public static void main(String args[]) {
  Map userMap = new HashMap();
  userMap.put("你好", "你也好");
  userMap.put("你吃早饭了吗？", "我吃过了，你呢？");
  userMap.put("我没有吃呢", "那我请你吃吧");
  userMap.put("好啊", "你吃什么呢？");
  userMap.put("我吃鸡蛋", "就吃这么点啊");
  userMap.put("我减肥呢", "哈哈");
  boolean f = false;
     InputStream is = null; OutputStream os = null;
  try {  
   ServerSocket s = new ServerSocket(8888);
   System.out.println("服务器开始运行！！！");
   while (true) {
    Socket s1 = s.accept(); 
    is = s1.getInputStream();
    os = s1.getOutputStream();
    DataInputStream dis = new DataInputStream(is);
    DataOutputStream dos = new DataOutputStream(os);
    
    //自定义代码
    do{
     String talk = dis.readUTF();
     dos.writeUTF("机器人说：" + userMap.get(talk) );
    }while(!f);
    
    
    //****
    
    dos.close();
    s1.close();
   }
  }catch (IOException e) {
   e.printStackTrace();
