How do you validate an Australian Business Number (ABN) format in Java?
<p>I need to validate an Australian Business Number format before submitting it for verification to the server. There seems to be solutions for <a href="http://www.clearwater.com.au/code" rel="nofollow">web/js</a> but none written in Java. Note that I do not need to validate the existence of the ABN, just the format.</p>
