MutableShort

public class org.apache.commons.lang3.mutable.MutableShort extends Number implements Comparable<MutableShort>, Mutable<Number>

A mutable short wrapper.

This class was created before the introduction of the java.util.concurrent.atomic package and the AtomicInteger class.

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

• Short

• AtomicInteger
