This class holds an array of int values. It provides threadsafe access to the array elements, treating each as if it was a volatile field, and defines atomic operations on them. The methods of this class are like those of AtomicInteger, except that each has an additional parameter that specifies the array index. Create an AtomicIntegerArray by specifying the desired array length or an actual int[ ] from which initial values can be copied.
