public static final class Atomic.Integer
extends java.lang.Number
int
record that may be updated atomically. An
Atomic@Integer
is used in applications such as atomically
incremented counters, and cannot be used as a replacement for an
Integer
. However, this class does extend
Number
to allow uniform access by tools and utilities that
deal with numerically-based classes.Modifier and Type | Field and Description |
