Program for Client - Server Communication to Display date using Java

     This is a program for displaying the date from server to client. Client is requesting the server to retrieve the current date.

Client:

import java.io.*;

import java.net.*;

import java.util.*;

class Client

{

            public static void main(String args[])

            {

            try

            {

                        Socket clsct=new Socket("127.0.0.1",139);

                        DataInputStream din=new DataInputStream(clsct.getInputStream());

                        DataOutputStream dout=new DataOutputStream(clsct.getOutputStream());

                        String str=din.readLine();

                        dout.writeBytes(str+'\n');

                        System.out.println(str);                      

                        clsct.close();

            }

            catch (Exception e)

            {

            System.out.println(e);

            }

            }

}

Server:

import java.io.*;

import java.net.*;

import java.util.*;

class Server

{

            public static void main(String args[])

            {

            try

            {

                        ServerSocket obj=new ServerSocket(139);

                       

                        while(true)

                        {

                                    Socket obj1=obj.accept();

                                   

                                    DataOutputStream dout=new DataOutputStream(obj1.getOutputStream());

                                    Date d=new Date();

                                    String S=d.toString();

                                    dout.writeBytes(S+'\n');

                       

                                    obj.close();

                        }

            }

            catch(Exception e)

            {

                        System.out.println(e);

            }

            }

}
