Ευχάριστα νέα για όσους δεν καλύπτονται από τις data structures του πακέτου java.util και του commons-collections της Apache (το οποίο υλοποιεί επιπλέον Interfaces και κλάσεις, όπως Bidirectional Maps, Queues, Bags, κ.α.). To Google-Collections έφθασε στην v1.0, και έρχεται να προσθέσει επιπλέον εργαλεία στην εργαλειοθήκη μας. Από το site:

The library consists of:

* New Collection types: Multimap, Multiset, BiMap and others
* High-performance immutable implementations of the standard collection types, for example ImmutableSet
* MapMaker, a builder for concurrent hash maps with many advanced features
* Ordering, which can only be described as a “Comparator on steroids”
* Iterators and Iterables utility classes: element-based equality, cycle, concat, partition, filter with predicate, transform with function, and much more
* Lists, Sets and Maps utility classes: a plethora of convenient factory methods and much more
* Forwarding collections, such as ForwardingSet, allowing you to customize collection behavior without subclassing
* Implementation helpers like AbstractIterator
* and still more
