Java does not use pointer, per se. Objects can have one or more references,
i.e,
Pizza pepperoni = new Pizza("Pepperoni");
pepperoni2 = pepperoni; // both pepperoni and pepperoni2 "point" to the same
object.
In Java, one must be mindful of the number of active objects on the heap; too
many, and you can receive an "OutofMemoryException". The number of objects
should be controlled by either nullifying the object when object is no longer
in use, or, if the object is no longer in use (no longer referenced), the
object will become eligible for garbage collection. The garbagecollection
mechanism in Java is not guaranteed to run at any specific time; however, you
can force the running of the garbage collector.
