| AtomicBoolean.java | Class |  A boolean value that may be updated atomically. | 
| AtomicInteger.java | Class |  An int value that may be updated atomically. | 
| AtomicIntegerArray.java | Class |  An int array in which elements may be updated atomically. | 
| AtomicIntegerFieldUpdater.java | Class |  A reflection-based utility that enables atomic updates to
 designated volatile int fields of designated classes.
 This class is designed for use in atomic data structures in which
 several fields of the same node are independently subject to atomic
 updates.
   Note that the guarantees of the compareAndSet method
 in this class are weaker than in other atomic classes.  | 
| AtomicLong.java | Class |  A long value that may be updated atomically. | 
| AtomicLongArray.java | Class |  A long array in which elements may be updated atomically. | 
| AtomicLongFieldUpdater.java | Class |  A reflection-based utility that enables atomic updates to
 designated volatile long fields of designated classes.
 This class is designed for use in atomic data structures in which
 several fields of the same node are independently subject to atomic
 updates.

| AtomicMarkableReference.java | Class |  An AtomicMarkableReference maintains an object reference
 along with a mark bit, that can be updated atomically.
  
   Implementation note.  | 
| AtomicReference.java | Class |  An object reference that may be updated atomically. | 
| AtomicReferenceArray.java | Class |  An array of object references in which elements may be updated
 atomically. | 
| AtomicReferenceFieldUpdater.java | Class |  A reflection-based utility that enables atomic updates to
 designated volatile reference fields of designated
 classes. | 
| AtomicStampedReference.java | Class |  An AtomicStampedReference maintains an object reference
 along with an integer "stamp", that can be updated atomically. |
