Converting number to letter
<p>Is there a nicer way of converting a number to its alphabetic equivalent than this?</p>

<pre><code>private String getCharForNumber(int i) {
    char[] alphabet = "ABCDEFGHIJKLMNOPQRSTUVWXYZ".toCharArray();
    if (i &gt; 25) {
        return null;
    }
    return Character.toString(alphabet[i]);
}
</code></pre>

<p>Maybe something than can deal with numbers greater than 26 more elegantly too?</p>
