Write a program on datagram socket for client/server to display the messages on client side, typed at the server side.

Sender

import java.util.*;

import java.net.*;

public class Sender

{

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

{

System.out.println("sender ");

DatagramSocket ds=new DatagramSocket();

Scanner s=new Scanner(System.in);

System.out.println("enter the message");

while(true)

{

String msg=s.nextLine();

InetAddress ip=InetAddress.getByName("127.0.0.1");

DatagramPacket dp=new DatagramPacket(msg.getBytes(),msg.length(),ip,3000);

ds.send(dp);

}

}

}

Receiver

import java.util.*;

import java.io.IOException;

import java.net.*;

public class Receiver

{

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

{

byte[] buf=new byte[1024];

System.out.println("receiver ");

DatagramSocket ds=new DatagramSocket(3000);

while(true)

{

DatagramPacket dp=new DatagramPacket(buf,1024);

ds.receive(dp);

String msg=new String(dp.getData(),0,dp.getLength());

System.out.println(msg);

}

}
