Overview
The AtomicInteger class represents an integer value that can be updated atomically, i.e. the read-modify-write operation can be executed atomically upon an instance of AtomicInteger. The class extends Number.
AtomicInteger makes for great counters as it uses the compare-and-swap (CAS) instruction under the hood which doesn’t penalize threads competing for access to the same data with suspension as locks do In general, suspension and ...
