public class MutableInteger
extends java.lang.Number
implements CloneableSerializable, java.lang.Comparable<MutableInteger>, EuclideanRing<MutableInteger>, Vectorizable
```
A mutable object containing an integer. It is meant to be used for cases where you may want to use a java.lang.Integer but its value will be updated frequently, such as in a map or other data structure. Many of the implementations of the methods in this class are based on the behavior described in java.lang.Integer.
