# Java: Exercise - Palindrome

## Problem

Write a method which returns true if the string parameter is a palindrome. A palindrome is any "word" which is the same forward and backward, eg, radar, noon, 20011002... The method should return false if the argument is not a palindrome.

## Signature

        public static boolean isPalindrome(String s)

Note: This is declared `static` because it is doesn't depend on instance variables from the class it would be defined in. It only depends on its parameters. It's declared `public` only because it might be generally useful.

## Extensions

You can make clever English palindromes more easily be ignoring spaces, nonalphabetics, and case (eg, "Drab as a fool, aloof as a bard.").

## Example

Call | Returns | Comments
--- | --- | ---
`isPalindrome("Hello")` | false | Not a palindrome.
`isPalindrome("radar")` | true | Is a palindrome.
`isPalindrome("Able was I ere I saw elba.")` | true | Is a palindrome.
`isPalindrome("A man, a plan, a canal -- Panama!")` | false | Not a palindrome by our definition. See extensions.

## Hints

Index simultaneously from both ends, comparing characters.

## Info on palindromes

Check out www.palindromes.org if you want to know more about them. This site has lots of amusing examples, eg, "Doc, note I dissent: a fast never prevents a fatness. I diet on cod." or "Drat Saddam, a mad dastard!"

## Assumptions

Write only the method. You can easily change the Example - Generic Calc program to use this method.
