UDP Protocol | Data Communication and Networking | Example


 Client

import java.util.*;

import java.io.*;

import java.net.*;

class Q2_Client{

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

        Scanner scan=new Scanner(System.in);

        DatagramSocket cSocket=new DatagramSocket();

        InetAddress iPAddress=InetAddress.getByName("localhost");

        byte[] sdata=new byte[1024];

        byte[] rdata=new byte[1024];

        System.out.println("\nEnter Number : ");

        int st=scan.nextInt();

        String s=String.valueOf(st);

        sdata=s.getBytes();

        DatagramPacket sPacket=new DatagramPacket(sdata, sdata.length, iPAddress, 0614);

        cSocket.send(sPacket);

        DatagramPacket rPacket=new DatagramPacket(rdata, rdata.length);

        cSocket.receive(rPacket);

        String mst=new String(rPacket.getData());

        System.out.println("\nCube of "+st+" is: "+mst);

        cSocket.close();

        scan.close();

    }

}

Server

import java.io.*;

import java.net.*;

class Q2_Server {

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

        DatagramSocket sSocket=new DatagramSocket(0614);

        byte[] sdata=new byte[1024];

        byte[] rdata=new byte[1024];

        while(true){

            DatagramPacket sPacket=new DatagramPacket(rdata, rdata.length);

            sSocket.receive(sPacket);

            String str=new String(sPacket.getData());            

System.out.println("\nConnection Established!!");

            //System.out.println("\nSending Data : "+cube);

            int cube=Integer.parseInt(str.trim());

            cube=cube*cube*cube;

            str=Integer.toString(cube);

            InetAddress iAddress=sPacket.getAddress();

            int port =sPacket.getPort();

System.out.println("\nSending Data : "+cube);

            sdata=str.getBytes();

            DatagramPacket sendPacket=new DatagramPacket(sdata, sdata.length, iAddress, port);

            sSocket.send(sendPacket);

        }

    }

}

Output


request a number from client-side and server will calculate the cube of the number and return it to client in response use udp protocol implementation,data communication and networking,concept of udp,concept of tcp,example of udp program
