Java chat application using TCP protocol for Client and Server

-

Simple Java chat application using TCP protocol with coeds for Client and Server to send Messages in string format

Code:


Server Code:

package clientserver;

import java.io.*;

import java.net.*;

class server

{

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

{

ServerSocket sersock = new ServerSocket(3000);

Socket sock = sersock.accept( );

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

OutputStream ostream = sock.getOutputStream();

PrintWriter pwrite = new PrintWriter(ostream, true);

InputStream istream = sock.getInputStream();

BufferedReader receiveRead = new BufferedReader(new InputStreamReader(istream));

String receiveMessage, sendMessage;

while(true)

{

if((receiveMessage = receiveRead.readLine()) != null)

{

System.out.println("Client:"+receiveMessage);

}

sendMessage = keyRead.readLine();

pwrite.println(sendMessage);

pwrite.flush();

}

}

}

Client Code:

package clientserver;

import java.io.*;

import java.net.*;

public class client

{

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

{

Socket sock = new Socket("localhost", 3000);

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

OutputStream ostream = sock.getOutputStream();

PrintWriter pwrite = new PrintWriter(ostream, true);

InputStream istream = sock.getInputStream();

BufferedReader receiveRead = new BufferedReader(new InputStreamReader(istream));

String receiveMessage, sendMessage;

while(true)

{

sendMessage = keyRead.readLine();

pwrite.println(sendMessage);

pwrite.flush();

if((receiveMessage = receiveRead.readLine()) != null)

{

System.out.println("Server:"+receiveMessage);

}

}

}

}

Simple Java program to Implement sorting algorithm using TCP on Server application Input: Give input on client side and client should receive sorted output from server and display sorted list on input(client) side. Note: You can implement any sorting algorithm by changing the sorting algorithm code on server side Code: Server: package aj.pkg7; import java.io.*; import java.net.*; import java.util.*; class Server { public static void main(String args[]) throws Exception { ServerSocket ss=new ServerSocket(1111); Socket s=ss.accept(); DataInputStream din=new DataInputStream(s.getInputStream()); DataOutputStream dout=new DataOutputStream(s.getOutputStream()); int r,i=0; int n=din.readInt(); int a[]=new int[n]; System.out.println("data:"); int count=0; for(i=0;i<n;i++) { a[i]=din.readInt(); } int number = a.length; for (int i1 = 0; i1 < number-1; i1++) for (int j1 = 0; j1 < number-i1-1; j1++) if (a[j1] > a[j1+1]) { int temp = a[j1]; a[j1] = a[j1+1]; a[j1+1] = temp; } ...
