REMOTE METHOD INVOCATION - PALINDROME

AIM:
    To write a Java program for the implementation of  Remote Method Invocation for palindrome.

ALGORITHM:

SERVER SIDE:
Step 1: Start
Step 2: Define the class rmiserver
Step 3: Create the object twox in try
Step 4: Register the object twox
Step 5: Display the exception in catch
Step 6: Stop

CLIENT SIDE:
Step 1: Start
Step 2: Define the class rmiclient
Step 3: Initialize the string s1 in try
Step 4: Create and Initialize the object onex
Step 5: Assign the value to m by calling the method palin
Step 6: Check whether the string is palindrome or not
Step 7: Display whether the string is palindrome or not
Step 8: Display the exception in catch
Step 9: Stop

SOURCE CODE: 

one.java
import java.rmi.*;
interface one extends Remote
{

    public int palin(String a) throws RemoteException;
}

two.java
import java.rmi.*;
import java.lang.*;
import java.rmi.server.*;
public class two extends UnicastRemoteObject implements one
{
    public two() throws RemoteException { }
    public int palin(String a) throws RemoteException
    {
        System.out.println("Hello");
        StringBuffer str = new StringBuffer(a);
        String str1 = str.toString();
        System.out.println("Print : " + str1.toString());
        StringBuffer str2 = str.reverse();
        System.out.println("Print : " + str2.toString());
        int b = str1.compareTo(str2.toString());
        System.out.println("Print : " + b);
        if (b == 0)
            return 1;
        else
            return 0;
    }
}

rmiserver.java
import java.io.*;
import java.rmi.*;
import java.net.*;
public class rmiserver
{
    public static void main(String args[]) throws Exception
    {
        try
        {
            two twox = new two();
            Naming.bind("palin", twox);
            System.out.println("Object registered");
        }
        catch(Exception e)
        {
            System.out.println("Exception" + e);
        }
    }
}

rmiclient.java
import java.io.*;
import java.rmi.*;
import java.net.*;
public class rmiclient
{
    public static void main(String args[]) throws Exception
    {
        try
        {
            String s1 = "rmi://localhost/palin";
            one onex = (one)Naming.lookup(s1);
            int m = onex.palin("madam");
            System.out.println("Print : " + m);
            if (m == 1)
            {
                System.out.println("The given string is a Palindrome");
            }
            else
            {
                System.out.println("The given string is not a Palindrome");
            }
        }
        catch (Exception e)
        {
            System.out.println("Exception" + e);
        }
    }
}
         
OUTPUT:

SERVER SIDE:

CLIENT SIDE:




















RESULT:
          Thus the Java program for the implementation of Remote Method Invocation for palindrome was performed and the output was verified.
