Google Collections Library 1.0 released

On December 30th, Google released version 1.0-final of its Google Collections Library, an extension of the Java Collection Framework. Google will make no more source- or binary- incompatible changes. However, Google reserves the right to make alterations to the serialised form of the objects, so developers are warned not to serialise objects into a database and expect to deserialise them at a later date.

Kevin Bourrillion, one of the two primary creators of the Google Collections Library, refers to his co-creation as solving “the same basic problems (as) the Java Collections Framework – just taken to the next level.” Google Collections Library simplifies code, cutting down the amount of low-level code that developers need to write and test. It also introduces new collection types, Multimap, Multiset and BiMap, and lists, sets and maps utility types.
