I'm working on creating a range of numbers between 1 and 2 using the imported math.random() class. Here's how I got it working so far, however I can't see how it would work: <pre class="prettyprint"><code>int tmp = (int)(Math.random()*1)+1; </code></pre> Anyonould?e know if that actually works to get the range? if not.. then what EDIT: Looking for either the number 1 or 2.

If you want the values 1 or 2 with equal probability, then <code>int temp = (Math.random() <= 0.5) ? 1 : 2;</code> is all you need. That gives you a 1 or a 2, each with probability 1/2.
