How to put a ignoreCase
<p>I want to put a ignore Upper/Lower case, punctuation, and spaces. Here is the code I want to invoke it into:</p>

<pre><code>public static boolean isPal(String s)
{
    if(s.length() == 0 || s.length() == 1)
        return true;
    if(s.charAt(0) == s.charAt(s.length()-1))
        return isPal(s.substring(1, s.length()-1));
    return false;
} 
</code></pre>
