write a client/server program using sockets (UDP or TCP) that will prompt the client user a number n, the server compute the fibonacci nth term and returns back to the client.

import java.net.*;
import java.io.*;

class tcpip_server
{
public static void main(String args[]) throws IOException
{
ServerSocket n1=null;
try
{
n1=new ServerSocket(98);
}
catch(IOException e)
{
System.err.println("Port 98 could not be found");
System.exit(1);
}
Socket c=null;
try
{
c=n1.accept();
System.out.println("Connection from "+c);
}
catch(IOException e)
{
System.out.println("Accept failed");
System.exit(1);
}
PrintWriter out=new PrintWriter(c.getOutputStream(),true);
BufferedReader in=new BufferedReader(new InputStreamReader(c.getInputStream()));
String n;
BufferedReader sin=new BufferedReader(new InputStreamReader(System.in));
System.out.println("Ready to type now");
while((n=sin.readLine())!=null)
{
out.println(n);
}
out.close();
c.close();
n1.close();
}
