  • Package java.util.concurrent.atomic A small toolkit of classes that support lock-free thread-safe programming on single variables.
  • A small toolkit of classes that support lock-free thread-safe programming on single variables. In essence, the classes in this package extend the notion of volatile values, fields, and array elements to those that also provide an atomic conditional update operation of the form: boolean compareAndSet(expectedValue, updateValue);
  • Atomic classes are not general purpose replacements for java.lang.Integer and related classes. They do not define methods such as hashCode and compareTo. (Because atomic variables are expected to be mutated, they are poor choices for hash table keys.)
  • ...4 more annotations...
  • The specifications of these methods enable implementations to employ efficient machine-level atomic instructions that are available on contemporary processors.
  • java.util.concurrent.atomic Class AtomicInteger java.lang.Object java.lang.Number java.util.concurrent.atomic.AtomicInteger
  • An int value that may be updated atomically. See the java.util.concurrent.atomic package specification for description of the properties of atomic variables. An AtomicInteger 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.
  • int incrementAndGet()           Atomically increments by one the current value.
