Google Collections LIbrary 1.0 final

Finally, the final version of the Google Collections Library has been released. This is a collection library that essentially complements the standard collections.
What is in Google Collections?

• Additional collection types Multimap, Multiset, BiMap
• There are also immutable types of collections that are convenient in multi-threaded programs.
• Utility Classes for Lists, Sets and Maps
• And much more…

I advise you to use this library in order not to create your bikes.
