日期和时间服务器 [英] Date and time server

问题描述

Dateclient.java:

  import  java.net。*; 
  import  java.io. *; 
  import  java.util。*; 
 
  public   class  dateclient 
 {
  public   static   void  main（字符串 ARGS []）
 
 {<跨度类= 代码关键字>尝试 {
插座S =新的Socket（InetAddress的.getLocalHost（）， 1000 ）; 
 BufferedReader br = new BufferedReader（ new  InputStreamReader（s.getInputStream（）））; 
 字符串输入; 
 PrintWriter out = new PrintWriter（s.getOutputStream（），true）; 
 
  while （（input = br.readLine（））！= null）
 {
 System.out。的println（输入）; 
 out.println（  Date& Time received ....）; 
 
} 
} 
  catch （例外e）{
 System.out.println（ 已重置与服务器的连接）;} 
} 
} 

Dateserver.java

  import  java.net。*; 
  import  java.io. *; 
  import  java.util。*; 
 
  public   class  dateserver  extends 主题
 {
  public   static  空隙主（<跨度类= 代码sdkkeyword >字符串 ARGS []）<跨度类= 代码关键字>引发异常
 {
 
 ServerSocket ss = new ServerSocket（ 1000 ）; 
 Socket s = ss.accept（）; 
 BufferedReader br = new BufferedReader（ new  InputStreamReader（s.getInputStream（）））; 
 PrintWriter out = new PrintWriter（s.getOutputStream（），true）; 
日期d =新日期（）; 
 尝试 
 {
  while （true）
 {
 out.println（ 服务器上的时间： + d.toString（）） ; 
 System.out.println（br.readLine（））; 
 sleep（ 1000 ）; 
} 
} 
 
 <跨度类= 代码关键字>捕获（IOException的发送）{的System.out.println（<跨度类=代码-string>  ---重置与客户端的连接---）; 
} 
} 
} 

他是javaEE的初学者。我遇到问题一旦服务器获得客户端的地址，从服务器到客户端的输入。

我没有收到客户端的收到日期和时间..输出。



PS：我的输出，只是它不打印线alone.Am试图太好了：d

解决方案

好吧，我复制你的代码并运行按原样。



首先启动服务器然后启动客户端，工作正常。我会在服务器中输入一个输出来指示它正在等待连接：

 System.out.println（  等待连接）; 
 Socket s = ss.accept（）; 
 System.out.println（ 收到连接）; 

此外，日期对象将保留在您只实例化一次的同时。更好的方法是在while循环中移动该行

Dateclient.java:

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

public class dateclient
{
public static void main(String args[])

{try{
	Socket s=new Socket(InetAddress.getLocalHost(),1000);
BufferedReader br=new BufferedReader(new InputStreamReader(s.getInputStream()));
String input;
PrintWriter out=new PrintWriter(s.getOutputStream(),true);

while((input=br.readLine())!=null)
{
	System.out.println(input);
	out.println("Date & Time received....");
	
}
}
catch(Exception e){
System.out.println("The connection to the server has been reset");}
}
}

Dateserver.java

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

public class dateserver extends Thread
{
public static void main(String args[]) throws Exception
{

ServerSocket ss=new ServerSocket(1000);
Socket s=ss.accept();
BufferedReader br=new BufferedReader(new InputStreamReader(s.getInputStream()));
PrintWriter out=new PrintWriter(s.getOutputStream(),true);
Date d=new Date();
try
{
while(true)
{
out.println("Time at server: "+d.toString());
System.out.println(br.readLine());
sleep(1000);
}
}

catch(IOException e){System.out.println("---Connection to client is reset---");
}
}
}

Hey am a begineer to javaEE.I have a problem receiving an input from server to client once the server gets the client's address.
Am not getting the "Date and time received.." output at the client.

PS:My output is good except that it doesnt print that line alone.Am trying too :D

解决方案

Okay, I copied your code and ran "as is".

Start the server first and then the client, works fine. I would put into the server an output to indicate that it's waiting for the connection:

System.out.println("Waiting for connection");
Socket s=ss.accept();
System.out.println("Connection received");

Also the date object will remain at the same time as you only instantiate it once. Better would be to move that line inside the while loop
