## Class MutableShort

- java.lang.Object
- - java.lang.Number
  - - org.apache.commons.lang3.mutable.MutableShort

- All Implemented Interfaces:
    Serializable, Comparable<MutableShort>, Mutable<Number>

      public class MutableShort
      extends Number
      implements Comparable<MutableShort>, Mutable<Number>

  A mutable `short` wrapper.

  Note that as MutableShort does not extend Short, it is not treated by String.format as a Short parameter.
