Security digit java multiplication
<p>Say the user inputs an int <code>123214</code></p>

<p>I have managed to separate the digits however how can i multiply the digits by one and other. </p>

<p>E.g. I want <code>1*2*3*2*1*4</code></p>

<p>I put all the single digits into an array but I can't multiply them by one and other as I want.</p>
