Factorial using RMI

RMI program for find factorial of a number

RMI interface

import java.rmi.*;
public interface myInterface extends Remote
{
    double fact(int i)throws RemoteException;
}

RMI server

import java.rmi.*;
import java.rmi.server.*;
public class myServer extends UnicastRemoteObject implements myInterface
{
    public myServer()throws RemoteException
    {
        super();
    }

    public double fact(int i)throws RemoteException
    {
        int f=1;
        int n=1;
        while(n<=i)
        {
            f=f*n;
            n++;
        }
        return(f);

    }
    public static void main(String args[])
    {
        try{
            myServer ms=new myServer();
            Naming.rebind("rmi://hsj./myInterface",ms);

/*  bolded area must replace with your computer name */
            System.out.print("Start...");
           
        }

        catch(Exception ex)
        {
            System.out.println(ex.getMessage());
        }
    }
}

RMI Client

import java.io.*;
import java.rmi.*;
public class myClient
{
    public static void main(String args[])throws IOException,RemoteException
    {
        int no;
           BufferedReader br=new BufferedReader(new InputStreamReader(System.in));
           System.out.print("Enter a no:");
          no=Integer.parseInt(br.readLine());
        try{

        myInterface mi=(myInterface)Naming.lookup("rmi://hsj./myInterface");
        double f=mi.fact(no);
        System.out.print("Factorial of "+no+" is:"+f );

        }
        catch(Exception ex)
        {
        }
       
    }
}
