Palindrome or Special Word Program - ICSE 2016 Computer Science

Special words are those words which starts and ends with the same letter.
Examples:
EXISTENCE
COMIC
WINDOW

Palindrome words are those words which read the same from left to right and vice-versa.
Examples:
MALAYALAM
MADAM
LEVEL
ROTATOR
CIVIC

All palindromes are special words, but all special words are not palindromes.

Write a program to accept a word and check and print whether the word is a palindrome or only special word.

Java 

import java.util.Scanner;
class Check{
    public static void main(String[] args){
        Scanner in = new Scanner(System.in);
        System.out.print("Enter the word: ");
        String w = in.next().toUpperCase();
        String rev = "";
        for(int i = w.length() - 1; i >= 0; i--)
            rev += w.charAt(i);
        if(w.equals(rev))
            System.out.println("Palindrome");
        else{
            char first = w.charAt(0);
            char last = w.charAt(w.length() - 1);
            if(first == last)
                System.out.println("Special word");
            else
                System.out.println("Not a special word");
        }
    }
}

Output

 
 OUTPUT 1: 
Enter the word: EXISTENCE
Special word 

 OUTPUT 2: 
Enter the word: MALAYALAM
Palindrome
