JPrimitiveCollections

Primitive data collections (char, int, float, long, double), including:

• array lists - primitive list API mirroring java.util.List
• bags (unordered lists) - a list of primitives which does not define a result order when an item is removed
• sorted lists - a sorted list of primitives, with no way to set or insert a value at a specific index to ensure the list remains sorted
• sorted maps - associate a primitive key with a generic value
• array views - wrap a primitive array, offset, and size in a list like API
• iterators - with primitive and boxed wrapper versions
• read only interfaces - e.g. IntListReadOnly with average(), get(int), toArray(), and toList(). Or IntSearchablewithcontains(int), indexOf(int), lastIndexOf(int), and size()`.

The primary purpose of these collections are to provide performance improvements over equivalent Java collections such as HashMap and ArrayList.

Take a look at the 'test' package for some examples of how the API works.
