Question

A palindrome is a word or a phrase that is the same when read both forward and backward. Examples are: "bob," "sees," or "never odd or even" (ignoring spaces). Write a program whose input is a word or phrase, and that outputs whether the input is a palindrome. Ex: If the input is: bob the output is: bob is a palindrome The code needs to be in Java.

Answer 1

Java code

import java.util.*;  
public class Palindrome
{       public static void main(String[] args)
    {     String input, reverse_input = "";  
              Scanner in = new Scanner(System.in);   
              System.out.print("Enter a word/phrase : ");  
              input = in.nextLine();   
              int length = input.length();   
              for (int l=length-1;l>=0;l--)  
                  reverse_input = reverse_input + input.charAt(l);  
              if (input.equals(reverse_input))  
                 System.out.println("Entered word/phrase ("+input+") is a palindrome");  
              else  
                 System.out.println("Entered word/phrase ("+input+") is not a palindrome");       
        }
}

Output :

Enter a word/phrase : neveroddoreven
Entered word/phrase (neveroddoreven) is a palindrome
