Socket Programming With JAVA

SocketClient.java work as Client

	import java.net.*;
	import java.io.*;
	import java.util.*;
	public class SocketClient
	{
	public static void main(String args[]) throws IOException
	{
	Socket s1 = new Socket("localhost",4444);
	while(true)
	{
	OutputStream s1out = s1.getOutputStream();
	DataOutputStream dos = new DataOutputStream (s1out);
	System.out.print("Enter String Which You Want To Send:- ");
	Scanner s=new Scanner(System.in);
	String str=s.next();
	dos.writeUTF(str);
	InputStream s1In = s1.getInputStream();
	DataInputStream dis = new DataInputStream(s1In);
	String st = new String (dis.readUTF());
	System.out.println(st);
	dis.close();
	s1In.close();
	s1.close();
	}//end while
	}
	}

SocketServer.java work as Server

	import java.net.*;
	import java.io.*;
	public class SocketServer
	{
	public static void main(String args[]) throws IOException
	{
	ServerSocket s = new ServerSocket(4444);
	try
	{
	while(true)
	{
	Socket s1=s.accept();
	InputStream s1In = s1.getInputStream();
	DataInputStream dis = new DataInputStream(s1In);
	String st = new String (dis.readUTF());
	System.out.println(st);
	OutputStream s1out = s1.getOutputStream();
	DataOutputStream dos = new DataOutputStream (s1out);
	System.out.print("Enter String Which You Want To Send:- ");
	Scanner s=new Scanner(System.in);
	String str=s.next();
	dos.writeUTF(s);
	dos.close();
	s1out.close();
	s1.close();
	}
	}
	catch(Exception e)
	{
	System.out.println(e);
	}
