The built-in collections for Java have good performance and are nice to use – especially with the new for-loop pattern. But are there alternatives? And if so, why should I use them? (Please use the comment functionality

- Commons Collections aka Jakarta Collection (Apache license)
- Google collections (Apache license)
- Concurrent Building Blocks (Apache license)
- Javolution (BSD license)
- GlazedLists collections (LGPL or MPL) from the glazedlists project
- (PriorityQueue from lucene project or also from commons collections)
- fastutil (LGPL)
There are also some older projects, which seem to be abandoned:
