https://github.com/eclipse/eclipse-collections/eclipse-collections: Eclipse Collections is a collections framework for Java. It has JDK-compatible List, Set and Map implementations with a rich API and set of utility classes that work with any JDK compatible Collections, Arrays, Maps or Strings. The iteration protocol was inspired by the Smalltalk collection framework.

This package contains implementations of the MutableBag interface. 
 A MutableBag is a Collection which contains elements that are unordered and may contain duplicate entries. It adds a protocol for adding, removing, and determining the number of occurrences for an item. 

    This package contains 3 bag implementations:




    This package contains one factory implementation:
