Experiment with the cost of garbage collection in your favorite language implementation. What kind of collector does it use? Can you create artificial programs for which it performs particularly well or poorly? Learn about weak references in Java. How do they interact with garbage collection? How do they compare to weak_ptr objects in C++? Describe several scenarios in which they may be useful.
