Write the code in Java Language. please refer the below image for reference.

Design and implement a simple chat system with

One server (multi-threaded) – multi clients

A client join or leave, notify all connected clients

A client send a message, broadcast the message to all clients

Client-side requirements (basic)

Ask the username of the user at the begin and notify the username to the server

Maintain a menu selection for the user:

Exit the system (leave the chat)

Get the list of users

User can type a chat message to send at any time

When data comes, display the data accordingly

Server-side requirements (basic)

Maintain the list of connected clients together with its username

Broadcast data to on connected clients, when

A new client joins (with the username)

A client sends chat message

A client exits the system (by the user)

A client loses its connection to the server

// CHAT CLIENT

import java.net.*;

import java.io.*;

public class chatclient

{

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

{

try

{

DatagramSocket s=new DatagramSocket();

InetAddress add= InetAddress.getLocalHost();

byte outbuffer[]=new byte[1024];

byte inbuffer[]=new byte[1024];

String data,x,str;

DataInputStream in =new DataInputStream(System.in);

System.out.println("Client window");

do

{

   DatagramPacket indata=new DatagramPacket(inbuffer,inbuffer.length);

   System.out.println("to server");

   str=in.readLine();

   outbuffer=str.getBytes();

   DatagramPacket outdata=new DatagramPacket(outbuffer,outbuffer.length,add,2000);

   s.send(outdata);

   s.receive(indata);

   data=new String(indata.getData()).trim();

   System.out.println("From Server:"+data);

}

while(!((data.equals("stop")||str.equals("stop"))));

}

catch(IOException e)

{

System.out.println(e);

}

}

}

//CHAT SERVER

import java.net.*;

import java.io.*;

public class chatserver

{

public static void main(String as[])throws IOException

{

try

{

DatagramSocket s=new DatagramSocket(2000);

byte outbuffer[]=new byte[1024];

byte inbuffer[]=new byte[1024];

String data,x,str;

DataInputStream in =new DataInputStream(System.in);

System.out.println("Server window");

do

{

   x=" ";

   DatagramPacket indata=new DatagramPacket(inbuffer,inbuffer.length);

   s.receive(indata);

   InetAddress add=indata.getAddress();

   int port=indata.getPort();

   data=new String(indata.getData()).trim();

   System.out.println("From Client:"+data);

   System.out.println("To client ");

   str=in.readLine();

   outbuffer=str.getBytes();

   DatagramPacket outdata=new DatagramPacket(outbuffer,outbuffer.length,add,port);

s.send(outdata);

   }

while(!((data.equals("stop")||(str.equals("stop")))));

}

catch(IOException e)

{

System.out.println(e);

}

}
