java.util.Imported @ jos.sf.net

Perhaps we need a discussion of CleanRoomIssues -- What exactly we can and can't do. (Just a thought.)

java.util is probably the easiest (large) package to do, as it has no native code and so will be easy to test even without other parts of JOS functioning.

Here is java.util; the full api can be found here. Sign up for something. Source is available from the SourceServer. (And no thanks to Sun for changing the 1.2 spec between betas 3 and 4.)

Interface Summary
Collection	The root interface in the collection hierarchy.
Comparator	A comparison function, which imposes a partial or total ordering on some collection of Objects.
Enumeration	An object that implements the Enumeration interface generates a series of elements, one at a time.
EventListener	A tagging interface that all event listener interfaces must extend
Iterator	An iterator over a Collection.
List	An ordered Collection (also known as a sequence).
ListIterator	An Iterator for Lists that allows the programmer to traverse the List in either direction and modify the list during iteration.
Map	An object that maps keys to values.
Map.Entry	A Map entry (key-value pair).
Observer	A class can implement the `Observer` interface when it wants to be informed of changes in observable objects.
Set	A Collection that contains no duplicate elements.
SortedMap	A Map that further guarantees that it will be in ascending key order, sorted according to the natural ordering of its keys (see Comparable), or by a Comparator provided at SortedMap creation time.
SortedSet	A Set that further guarantees that its iterator will traverse the Set in ascending element order, sorted according to the natural ordering of its elements (see Comparable), or by a Comparator provided at SortedSet creation time.

Class Summary
