import java.io.BufferedWriter;
import java.io.IOException;
import java.io.InputStreamReader;
import java.io.OutputStreamWriter;
import java.io.PrintWriter;
import java.net.ServerSocket;

public class ServerCode {

	public static int portNo=15002;
	
	public static void main(String[] args) {
		
		Socket socket=null;
		ServerSocket serverSocket=null;
		try {
			serverSocket=new ServerSocket(portNo);
			socket=serverSocket.accept();
			System.out.println("Accept the Client:"+socket.toString());
			
			BufferedReader in=new BufferedReader(new InputStreamReader(socket.getInputStream()));
			PrintWriter out=new PrintWriter(new BufferedWriter(new OutputStreamWriter(socket.getOutputStream())),true);
			
			while(true){
				String str=in.readLine();
				if(str!=null){
					System.out.println("In Server reveived the info :"+str);
					out.println(str);

			}
			
		} catch (Exception e) {
		}finally{
			try {
