Palindrome Program - ICSE 2007 Computer Science

Write a program using a method palin(), to check whether a string is a palindrome or not. A palindrome is a string that reads the same from left to right and vice-versa.
Example: MADAM, ARORA, ABBA

Java 

import java.io.*;
class Palindrome{
    public static void main(String args[])throws IOException{
        BufferedReader br = new BufferedReader(new InputStreamReader(System.in));
        System.out.print("String: ");
        String s = br.readLine();
        if(palin(s))
            System.out.println(s + " is palindrome.");
        else
            System.out.println(s + " is NOT palindrome.");
    }
    public static boolean palin(String w){
        String rev = "";
        for(int i = w.length() - 1; i >= 0; i--)
            rev += w.charAt(i);
        return w.equalsIgnoreCase(rev);
    }
}

Output

 
 OUTPUT : 
String: MADAM
MADAM is palindrome.
