1 A phantom reference is used to determine when an object is just about to be reclaimed
2 A program that displays a class synopsis for the named class
3 A soft reference holds onto its referent until memory becomes low
4 A tree structure that maps inheritance hierarchies of classes
5 A weak reference is used to determine when an object is no longer being referenced
