import java.io.IOException;
import java.io.PrintStream;
import java.net.Socket;

public class Client
{
public static void main(String a[]) throws IOException
{
Socket s = new Socket("LocalHost",8000);

while(true)
{
String str=in.readLine ();
System.out.println("msg received:"+str);
if(str.equals("end"))
{

break;
}

String str1=inn.readLine ();
dos.println(str1);
if(str1.equals("end"))
{
s.close();
break;
}
}
}
}
