RMI Using java Example

 

 

 

First of All Create Interface

import java.rmi.*;

public interface interfacestudent extends Remote
{
    public double getPercent(String name)throws RemoteException;
    public double getCount(char sex)throws RemoteException;
    public double getAvg(char sex)throws RemoteException;
   
}

interface.java

Second Implement interface

import java.rmi.RemoteException;
import java.rmi.server.UnicastRemoteObject;

public class implstudent extends UnicastRemoteObject implements interfacestudent

{

    String name[]={"Sanjay","Chauhan","KK","Vivek","Vishal","Katrina","Anushka"};

    double percent[]={99.99,88.88,77.77,66.66,55.55,44.44,33.33};

    char sex[]={'m','m','m','m','m','f','f'};

    

    public implstudent() throws  RemoteException

    {

        super();

    }        

    

    public double getPercent(String nm)throws RemoteException

    {

        for(int i=0;i<name.length;i++)

        {

            if(nm.equals(name[i]))

            {    

                return  percent[i];

            }    

        }    

       return 0.0;

    }

    public double getCount(char sx) throws RemoteException

    {

        double cnt=0.0;

        for(int i=0;i<sex.length;i++)

        {

            if(sex[i]==sx)

                cnt++;

        }

        return cnt;

    }

    public double getAvg(char sx) throws RemoteException

    {

        double cnt=0;

        double sum=0;

        for(int i=0;i<sex.length;i++)

        {

            if(sex[i]==sx)

            {    

                cnt++;

                sum+=percent[i];

            }   

        }

        return sum/cnt;

        

    }

      

}

implestudent.java

Now Bind RMI with Server

import java.rmi.registry.LocateRegistry;
import java.rmi.registry.Registry;

public class Server
{
    public static  void main(String atgs[])
    {
        try
        {
            interfacestudent ifs;
            ifs=new implstudent();
            Registry r;
            r=LocateRegistry.createRegistry(6000);
            r.bind("Stud1", ifs);
            System.out.println("Server is waiting....");
        }
        catch(Exception ex)
        {
            System.out.println(ex.toString());
        }  
      
    }      
}

Server.java

Now implement Client

package internalassign;


import java.rmi.Naming;
import java.rmi.NotBoundException;
import java.rmi.RemoteException;

public class client
{
    public static void main(String[] args) throws RemoteException, NotBoundException
    {
        try
        {
            interfacestudent ifs=(interfacestudent)
            Naming.lookup("rmi://127.0.0.1:6000/Stud1");
            double per=ifs.getPercent("Vivek");
            System.out.println(per+"");
           
            double cnt=ifs.getAvg('f');
            System.out.println(cnt+"");
           
            double avg=ifs.getAvg('m');
            System.out.println(avg+"");
        }
        catch (Exception ex)
        {
           System.out.println(ex+"");
        }
       
    }       
   
}
 

client.java 

first of all run server.java

second run client.java
