Invoke another class's method, passing object name as argument
<p>New to Java, trying to code a basic traffic simulation where I have an Intersection class and an SimEngine (event list) class.</p>

<p>My Intersection class has a method called Arrival() indicating that a car has arrived at the intersection.  As part of the method, I want to schedule a departure for that car at a timestamp 3 seconds later using the schedule() method in SimEngine.</p>

<p>The schedule() method takes four arguments: (What we're scheduling, the vehicle ID, the Intersection id, the timestamp).  My question is about passing the Intersection id (this simulation has multiple intersections).  If I don't know the name of the Intersection object's reference variable, how can I pass it to another function?</p>
