Socket Programming using TCP/IP------------ Write an application to send “hello” message from server to client using TCP/TP.

Aim: - Write an application to send “hello” message from server to client using TCP/IP.

Tools: - NetBeans IDE, jdk

Program:-

 

Server.java

package srvr;

import java.io.*;

import java.net.ServerSocket;

import java.net.Socket;

import java.net.UnknownHostException;

public class Srvr {

    public static void main(String[] args) throws Exception {

        ServerSocket sc=new ServerSocket(777);

        Socket s=sc.accept();

        System.out.println("Server is Ready...");

        BufferedReader br=new BufferedReader(new InputStreamReader(s.getInputStream()));

        String str;

        System.out.print("String  From Client : ");

        while((str=br.readLine())!=null)

        {

            System.out.print(str);

        }

        System.out.println();

        s.close();

        br.close();       

    }

}

Client.java

package srvr;

import java.io.BufferedReader;

import java.io.InputStreamReader;

import java.io.PrintStream;

import java.net.ServerSocket;

import java.net.Socket;

public class clnt {

    public static void main(String[] args) throws Exception {       

        Socket s=new Socket("localhost", 777);

        System.out.print("Enter String : ");

        BufferedReader br=new BufferedReader(new InputStreamReader(System.in) );

        String str=br.readLine();

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

        ps.println(str);

        System.out.println("String Sended To Server...");      

        ps.close();

        s.close();       

    }    

Output:-
