RMI (Remote Method Invocation)-----Write an RMI Program to Fibonacci series summation.

Aim: - Write an RMI Program to Fibonacci series summation.

Tools: - NetBeans IDE, jdk

Program:-

 

Interface:-

 

import java.rmi.Remote;

public interface demointfs extends Remote {           

    public int[] prntmsg(int x) throws Exception;

}

 

Server:-

 

import java.rmi.registry.LocateRegistry;

import java.rmi.server.UnicastRemoteObject;

import java.io.*;

import java.sql.*;

import java.net.*;

import java.io.DataOutputStream;

import java.io.PrintStream;

 

public class demoserver implements demointfs{   

    private String message;

    String s;

    public int[] prntmsg(int x) throws Exception{

            int a=0,b=1,res=0,i=0,j=2;

            int ary[]=new int[x];   

            ary[i]=a;

            i++;

            ary[i]=b;

            i++;     

while(j<x){

                        res=a+b;

                        a=b;

                        b=res;

                        ary[i]=res;

                        i++;

                        j++;                             

            }

            return ary;       

    }

    public static void main(String[] args) throws Exception {

        demoserver h=new demoserver();

        demointfs stub=(demointfs)UnicastRemoteObject.exportObject(h,0);

        java.rmi.registry.Registry registry= LocateRegistry.getRegistry();

        registry.rebind("hello", stub);     

        System.out.println("Server is ready");   

    }

}

 

Client:-

 

import java.rmi.NotBoundException;

import java.rmi.registry.LocateRegistry;

import java.rmi.registry.Registry;

import java.io.IOException;

import java.io.BufferedReader;

import java.io.InputStreamReader;

public class client  {

    public static void main(String args[]) throws Exception{

            int i;

             BufferedReader br=new BufferedReader(new InputStreamReader(System.in));       

            System.out.println();

            System.out.print("Enter Number  : ");    

              String str=br.readLine(); 

            int nm=Integer.parseInt(str);     

            Registry reg=LocateRegistry.getRegistry("localhost");

            System.out.println("Fibonacci Series : ");

            demointfs h=(demointfs)reg.lookup("hello");

            int a[]=h.prntmsg(nm);

            for(i=0;i<a.length;i++)

            {

                        System.out.println(a[i]);

            }

}     

}

Output:-
