MutableSet
MutableSet is a data structure in computer science that combines the features of a set and a list. It represents an unordered collection of unique elements, but unlike a set, it allows the addition, removal, and modification of elements.
A set, in the context of a MutableSet, is an unordered collection of unique elements. This means

* Duplicate elements are not allowed
* Elements are typically immutable
* The set is not indexed or ordered
MutableSets are useful when the order of elements does not matter and modifications to the collection need
Many programming languages and libraries provide implementation of MutableSets. For example, the Apache Commons Collections library
