Can someone explain to me how time (t) is understood in this java exercise?
<p>In going through the PlayThatTuneDeluxe.java program in class today, my professor didn't really explain where the "time" or "t" variable is from and how we <em>know</em> to use it.</p>

<p>The program is here: <a href="http://introcs.cs.princeton.edu/java/21function/PlayThatTuneDeluxe.java.html" rel="nofollow">Play that tune deluxe</a></p>

<p>I understand the concept of assigning a variable for time or duration and using "t" as that variable, but I don't understand where the program is getting that variable from? How do I know to add "t" and that it's used to determine time\duration?</p>

<p>Thanks.</p>
