conditional variable?
<p>I'm not really sure what this is called so it's hard to look it up and it is best if I show you what I'm trying to do.</p>

<p>I want to create a condional variable of sorts</p>

<pre><code>String fileName = (if (this.filename != null) { return this.filename; } 
                   else { return "default value"; }); 
</code></pre>

<p>This should be pretty clear on what I'm trying to do. I want to use some sort of condition to set this variable based on another variables input, in this case whether or not it equals null or not.</p>
