String helper method
<p>I need a little help on how i could put in a helper method. This is the helper method I wrote.</p>

<pre><code>public static String helper(String help) {
    help = help.toLowerCase();
    help = help.replaceAll("\\s+", "");
}
</code></pre>

<p>and this is how i used it in main method.</p>

<pre><code>String help = RecursivePalindrome.helper(x);
</code></pre>

<p>If I keep it like this then on the helper method they ask me for a return value but if i put the <code>return help;</code> then the method doesn't execute correctly. If I change the helper method to void then i cant put String help on my main method. </p>

<p>This is what happens when i run the program:</p>

<pre><code>Enter a word to test whether it is a palindrome or not(press quit to end.): RaceCar
'RaceCar' is not a palindrome.
</code></pre>

<p>See i put the helperclass to ignore the upper cases but it wont. RaceCar would be a palindrome but the uppercase makes the program say its not.</p>
