### 1. INTRODUCTION

The Collections package contains a set of Java classes that extend or augment the Java Collections Framework. This includes new interfaces and new implementations together with supporting utility classes.

### 5. ACTION ITEMS

Want to help? Here's some "to do" items the team has identified.

Action Item | Volunteer
--- | ---
Additional Contributions. Other collection or collection-related classes or decorators. |
MultiMap ideas. Updates to MultiMap, maybe based on this library. |
Additional Documentation. Create simple User's Guide, examples, or other documentation for this package. |
Serializable Collections. All of the concrete Collection and Map implementations should be properly Serializable across all versions of the JDK. Also, decorators should be Serializable if the underlying instance is. |
Fail-Fast Iterators. All concrete Collection and Map implementations that can have fail-fast iterators should have them. Some classes, like StaticBucketMap, cannot possibly have fail-fast iterators, but otherwise everything else should. |
LoopingListIterator. A ListIterator similar to LoopingIterator
Additional Unit Tests. Create generic unit tests for SortedSet and Buffer. |
