When using a hash-based Collection or Map such as HashSet, LinkedHashSet, HashMap, Hashtable, or WeakHashMap, make sure that the hashCode() of the key objects that you put into the collection never changes while the object is in the collection. The bulletproof way to ensure this is to...
Implement java.util.Set as desired by multiple users. I ran edge cases with nulls through a HashSet and implemented according to its true/false results. An initial review was performed here.
