This is a simplest chat program .


package Chat;

import java.net.*;
import java.io.*;
import java.util.*;
class ChatServer
{
    public static void main(String[] args) throws Exception
    {
        ServerSocket ss=new ServerSocket(9093);
        Socket s=ss.accept();
        System.out.println(s);
        BufferedReader bf=new BufferedReader(new InputStreamReader(s.getInputStream()));
        BufferedReader br=new BufferedReader(new InputStreamReader(System.in));
        PrintWriter pw=new PrintWriter(s.getOutputStream(),true);
        try{
                   
            while(true)
            {
                String name=bf.readLine();
                System.out.println("Client :" +name);
                String x=br.readLine();
                pw.println("Server : " + x);
       
            }
        }
        catch(SocketException se)
        {
            System.out.println("Client has been closed its connection");
        }
       
       
    }
}

class ChatClient
{
    public static void main(String[] args) throws Exception
    {
        BufferedReader br=new BufferedReader(new InputStreamReader(System.in));
        System.out.println("Enter ip of server");
        String ip=br.readLine();
        Socket ss=new Socket(ip,9093);
        System.out.println(ss);
        PrintWriter pw=new PrintWriter(ss.getOutputStream(),true);
        BufferedReader bf=new BufferedReader(new InputStreamReader(ss.getInputStream()));
        while(true)
        {
            String st=br.readLine();
            System.out.println("Client : " + st);
            pw.println(st);
            System.out.println(bf.readLine());
        }
    }
}
