基于套接字Socket通信的编程

编写一个时间服务器/客户程序，当服务器收到客户端请求后，将当前的系统时间以一定的格式发送给客户端，客户端解析这个格式，并以可读的格式在标准输出设备上打印接收到的时间。


谁会呀？我是初学者，大侠帮帮忙！

import java.io.*;
import java.net.*;

public class Client {
    public static void main(String[]args){
        String s=null;
        Socket socket;
        DataInputStream in=null;
        DataOutputStream out=null;
        try{
            socket=new Socket("localhost",4331);

            while(true){
                s=in.readUTF();
                out.writeUTF(":"+Math.random());
                System.out.println("client get****:"+s);
                Thread.sleep(2000);
            }
        }catch(IOException e){
            System.out.println("can't connect");
            
        }catch(InterruptedException e){}
    }

}



package awt;

import java.io.*;
import java.net.*;

public class Serever {
    public static void main(String [] args){
        ServerSocket server=null;
        Socket socket=null;
        String s=null;
        DataOutputStream out=null;
        DataInputStream in=null;
        try{
            server=new ServerSocket(4331);
        }catch(IOException e1){
            System.out.println("ERROR:"+e1);
        }try{
            socket=server.accept();
            in=new DataInputStream(socket.getInputStream());
            out=new DataOutputStream(socket.getOutputStream());
            while(true){
                s=in.readUTF();
                out.writeUTF("It's Server:");
                out.writeUTF("client sends:"+s);
                Thread.sleep(2000);
            }
        }catch(IOException e){
            System.out.println(""+e);
        }catch(InterruptedException e){}
    }

}

自己改一下
