Create a distributed application using RMI where the client will handshake with the server by invoking the remote method public void sayHello() where client and server are on different hosts in the same network - ( Remote Invocation Method)

Program:-

RMI_Client.java

import java.rmi.*;
import java.net.MalformedURLException;
import java.nio.charset.MalformedInputException;

public class _1_rmi_client {
publicstaticvoid main(String[] args)throws NotBoundException,MalformedURLException,RemoteException{
      _1_rmi_interface obj = (_1_rmi_interface) Naming.lookup("rmi://localhost:4444/sayHello");
            obj.sayHello();
        }
}

RMI_Server.java:-

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

public class _1_rmi_server {
    public static void main(String[] args) throws RemoteException{
        Registry registry = LocateRegistry.createRegistry(4444);
        registry.rebind("sayHello", new _1_rmi_servant());
        
    }
}

RMI_Interface.java:-

import java.rmi.*;

public interface _1_rmi_interface extends Remote{
    public void sayHello() throws RemoteException;
}

RMI_Servant.java:-

import java.rmi.*;
import java.rmi.server.UnicastRemoteObject;

public class _1_rmi_servant extends UnicastRemoteObject implements _1_rmi_interface {
    public _1_rmi_servant() throws RemoteException{
        super();
    }

    public void sayHello() throws RemoteException{
    System.out.println("Hello Server again ");
    }
}

Output:-
