TCP PROGRAM(Date and Time client server)

AIM

To create date and time client server using the TCP protocol

ALGORITHM

Server

Declare the necessary arrays and variables.
Set server port address using socket().
Get the current message.
Connect to the client.
Stop the process.

Client

Set the client machine address.
Connect to the server.
Read from the server the current message.

Close the connection.

PROGRAM

DateClient:

import java.net.*;

import java.io.*;

public class DateClient

{

public static void main (String args[])

?????????? {

???????????????????????????? Socket soc;

DataInputStream dis;

???????????????????????????? String sdate ;

PrintStreamps;

try

??{

InetAddressia=InetAddress.getLocalHost();

soc=new Socket(ia,8020);

dis=new DataInputStream(soc.getInputStream());

sdate=dis.readLine();

System.out.println("THE date in the serveris:"+sdate);

ps=new PrintStream(soc.getOutputStream());

ps.println(ia);

?????????? ????????????????????????????????}

catch(IOException e)

?????????????????????????????????????????????? {

System.out.println("THE EXCEPTION is :"+e);

?? }

?????????????????????? }

}

DateServer:

import java.net.*;

import java.io.*;

importjava.util.*;

public class DateServer

{

public static void main(String args[])

?????????? {

ServerSocketss;

Socket s;

PrintStreamps;

DataInputStream dis;

String inet;

try

?????????????????????????? {

ss=new ServerSocket(8020);

while(true)

?????????????????????????????????? {

??s=ss.accept();

ps=new PrintStream(s.getOutputStream());

???????? Date d=new Date();

ps.println(d);

dis=new DataInputStream(s.getInputStream());

inet=dis.readLine();

System.out.println("THE CLIENT SYSTEM ADDRESSIS :"+inet);

ps.close();

?????????????????????????????????? }

?? }

catch(IOException e)

???????????????????????????????????????? {

System.out.println("The exception is :"+e);

??}

?????????????? }??????????????

}

OUTPUT:

DateClient:

C:\Program Files\Java\jdk1.6.0\bin>javac dateclient.java

C:\Program Files\Java\jdk1.6.0\bin>java dateclient

THE date in the server is:Sat Jul 19 13:01:16 GMT+05:30 2008

C:\Program Files\Java\jdk1.6.0\bin>

DateServer:

C:\Program Files\Java\jdk1.6.0\bin>javac dateserver.java

C:\Program Files\Java\jdk1.6.0\bin>java dateserver

THE CLIENT SYSTEM ADDRESS IS :com17/192.168.21.17

RESULT: Thus the output has been executed and verified successfully for date and time client server
